Blank internal screen. Is it the inverter?

Message

slaterlp · #1 Post by **slaterlp** » Sat Mar 09, 2013 1:12 pm

Hi all,

T60 1952A97 14" screen.

My internal screen went blank today. If I turn the laptop off and back on again, the screen will work for maybe a minute and then go blank again.

If I boot to bios the same thing happens, so I know it's not software.

If I connect an external screen, as I am running now to post this thread, the external screen works fine. I can also switch over to the internal screen, or both at the same time, but the internal screen will only stay on for at the most a minute before going blank again.

I can just make out the faint images of what is on the screen when it goes blank.

Is this a failed inverter?

If so, what is the correct part number?

I have removed the screen bezel, and there is a number on the inverter board FRU p/n 41W1010.

Is this the only inverter that will work on this lcd display?

If so, does anyone know how much they are in the UK, and where I can get one?

Thanks.

PS. Will FRU P/N 41W1338 work, or is this for a different size display?

Could be a bad inverter, but it's not likely. A failing inverter will often start buzzing before it dies. Most likely it's the CCFL that has gone bad. I've had a few that would act just like you describe, and it was a failing lamp every time.

FRU 41W1010 is the correct inverter for your screen. The 41W1338 is for the 15.4" widescreen models.

Hi Neil,

Thanks for that. What's the CCFL and is this something that can be changed easily? Is there a part number for it?

Here's another update.

When I use the function key with the screen selector, to get the internal screen going again along with the external screen, the inverter board starts to get really hot and I can smell it burning. Just as I start to smell it, the screen goes blank and the inverter board cools down. Meanwhile the external screen continues to stay on without a problem.

I suspect it would also get hot without the external screen too. Should it be getting hot? When it gets hot, it is hot enough to burn the tip of my finger. --- I am running it without the bezel in place so the inverter board is visible to me.

Thanks

See this for more inverters: http://forum.thinkpads.com/viewtopic.php?f=11&t=109016

But like Neil said they are not your problem.
It's your CCFL (Cold Cathode Fluorescent Light) tube that's burnt through.
It works for a few seconds, heats up and then conks out.
Cools down, work again for a few seconds, etc.
A 14.1" CCFL is a pig to replace, buy a new/used complete LCD.
Make sure you get one with an IBM P/N or FRU, and not a "100% compatible", they are NOT!
You might consider upgrading to an SXGA+ (1400x1050) screen.
Easiest would be to buy a whole lid.

Hi black stuff.

Thanks for that, I'll have a search for one.

I know you say it's not the inverter, but I've now noticed that where it gets hot is a small copper section that several components are soldered to, and the solder has come away from one or two of the legs of those components. Pity I can't post a picture to show you what I mean.

If you get a whole lid, you also get another inverter, problem(s) solved.

slaterlp · #7 Post by **slaterlp** » Sun Mar 10, 2013 5:25 am

Hi, thanks black stuff.

The trouble is, I can't find a new complete lid.

Anyway, my T60 is 4 years old, if I buy another 2nd hand display, I have no way of knowing how long it will last. So I'd much rather buy the new parts and fix my own, especially as I'm more than capable of taking this apart and putting it back together again.

Does anyone know a UK based supplier of the new parts for Lenovo T60's? There are plenty in the USA, but the shipping costs seem to be pretty high.

Where can I buy the backlight and inverter in the UK?

Thanks.

I bought the backlight for my 2007-44G T60 from the supplier that comes up first in a google search for "backlight uk". I'm not posting it publicly so it is considered advertising. I have no connection with the seller, he just happened to be in B'ham and I conveniently drove there. It cost £8.82.

Now, fitting the backlight succesfully is another story. I can't say 100% that mine works yet, because I had a short circuit (which I neglected to check, before firing up) and burned my inverter. Now I have double checked that my backlight is properly installed, but I'm still looking for an inverter to fire it up and confirm if it works or not. The only offer I got for an inverter (so far) was $15 shipped from the US. Let me know if this is a good price for you and I could PM the seller's details.

There's no problem on the forum if you mention a reliable supplier.
It saves time for the next person, who might not be able/willing to contact you for the nitty-gritty.
So go ahead, post it.

As to CCFL-replacement, check this (for 15"): http://forum.thinkpads.com/viewtopic.php?f=31&t=88991

Crappy website but I have to admit they stock quite a huge variety of CCFL's

slaterlp · #11 Post by **slaterlp** » Mon Mar 11, 2013 8:48 am

OK here's an update.

First, thanks to black stuff and ilakast for those very helpful replies.

I found inverters FRU 41W1010 for £13.60 on ebay free postage from Hong Kong. A couple of different outlets.

I found the screen, NEW Samsung LTN14XA-L01 for £59.90 on ebay Item number:310479334257f ree postage from West Drayton, United Kingdom.

And from the link ilakast posted (backlightweb.co.uk) the lamp is a 2x290mm.
with wires £12 plus vat plus £4 postage, or without wires £7 plus vat plus £4 postage.

So what do I buy?
Here's more info on my display behaviour.
I has a pink/reddish tinge. Sorry forgot to mention that earlier.
If I turn the brightness down, it will stay on indefinitely, no problem other than that it's dim too dim to use really.
If I turn the brightness up a bit say to midway, it will stay on for about 10 mins max.
If I turn it up higher, it goes out after about 1 minute max.
Each time, just before the screen goes black, the inverter gets hot, -- hot enough to smell it, but it doesn't buzz or make any noise at all.

I Spoke with the chap from backlightweb.co.uk, and he confirmed that with the pink tinge on my display, the lamp is definitely shot or very nearly. He thought that the inverter is probably ok, but the only way to really tell is to replace the lamp or the complete screen.

So my thinking is this.
The lamp is either gone or is on it's way out. Even if the cause of the blacking out is a defective inverter, I will still have to replace the complete screen or lamp eventually/soon anyway.

So on the basis that the backlight in the screen has had it, I might as well try and remove the backlight before buying a complete new screen.

Question
I have an external monitor. If I remove the screen from the laptop, can I use the laptop? Will do any damage running the laptop without the internal screen connected?

This or any screen that is described as "compatible" will NOT work with an IBM laptop. It has to be an exact IBM FRU part, for example 13N7051 for a 14.1'' Samsung, etc. So, stay away from that option.

slaterlp wrote:Question

Absolutely. No harm at all. This is how I am using my T60 on a daily basis: http://forum.thinkpads.com/viewtopic.ph ... 66#p704966

It's not an easy task to replace the CCFL but I guess you have nothing to lose.

slaterlp · #13 Post by **slaterlp** » Mon Mar 11, 2013 12:28 pm

Hi ilakast, thanks for confirming I can run without the internal display.

LCD removal
Just to confirm, can I just unplug the lcd from the ribbon lead and leave the lead lying in the cover -- as long as I insulate and make sure it doesn't short of course -- and remove the lcd completely. I assume it's ok to leave the inverter connected to its ribbon connector for the status lights?

LCD compatibility
Now I'm a bit confused.

According to http://www.thinkwiki.org/wiki/TFT_display#TFT_display

The Samsung LTN141XA-L01, 14.1, 1024x768.
FRU's ---- 13N7051,13N7052,13N7050,92P6759,42T0363
Fits ------ T40, T41, T42, R50, R50e, R51, R51e, R52, T60

My lcd is definitely a samsung LTN141XA-L01. If I get one of those, won't it be a definite fit?
Could you please explain the compatibility issue for me. I certainly don't want to buy the wrong screen that's for sure.

CCFL removal from the lcd
Took my lcd out today for an exploratory. I read your (ilakast) post about removing the ccfl and damaging it in the process of wanting to swap it to another screen. Presumably then installing one is easier than removing one?

Can you tell me where in the lcd the ccfl is located exactly? Is is at the bottom, the top, or the side. I didn't want to dig around too much, until I know for certain where it is. Do you have any pics you could send me? slpj (at) btconnect (dot)com.

Thanks in anticipation.

T60 has a whitelist of screens in BIOS. Unless you install a panel with a FRU number (which equals Lenovo-approved firmware), you'll get no image on boot, regardless whether it's "technically" the same screen..

No offense meant, but you shouldn't attempt any CCFL-related work if you have to ask the above quoted questions.

While I agree with George...there was a first time for all of us who have replaced lamps.... So, it's located along the bottom of the panel.

It's a very difficult procedure to remove the old lamp without damaging the LCD panel, and even more difficult to keep dust from getting between the layers of the panel once it's apart. Unless you are very lucking, you will likely end up destroying the first panel or two you work on. But, if you don't try, you'll never develop the skills.

Read the link RealBlackStuff posted above...it's one of the best guides you'll find for this job. You can also find some YouTube videos showing how it's done.

slaterlp · #16 Post by **slaterlp** » Mon Mar 11, 2013 1:34 pm

Thanks for the explanation about the bios list ajkula66. You also said,

As regards that, and with respect, I've never been to scotland either, but I'd have no trouble finding my way to Loch Ness with some directions. As Neil just posted, there's a first time for everything, and I've had many first times. So again with the greatest respect, I find your comment a little condescending and arrogant if I may say so -- without offense.

. Besides as I said, my lcd is kaput anyway unless I change the ccfl, so I have now't to lose do I.

Thanks for the tip on the location Neil, I'll have a go as soon as I get the time. Maybe tomorrow, now that I know I can run the laptop without it.

I'd rather be looking for Loch Ness than swapping a CCFL bulb on a Samsung panel, presuming I've never done either of these on a previous occasion...just by reading other people's experiences...but that's me.

Having done both in real life - in fairly distant past - I'd still stick to attempting to find my way to Loch Ness...

So again with the greatest respect, I find your comment a little condescending and arrogant if I may say so -- without offense. . Besides as I said, my lcd is kaput anyway unless I change the ccfl, so I have now't to lose do I.

No offense taken. I've been called a *lot* worse - my favourite episode involved being compared to Rush Limbaugh on Lenovo's forum - not kidding. Let me just point the following out to you:

a) While your LCD is as good as dead right now, the chances of you breathing new life into it without making it actually worse in other respects are slim to none. People who swap CCFLs professionally tend to stay away from Samsung (as well as Hydis) panels with a good reason.

b) All of us are entitled to define value of our own time. For me personally, a panel which can be bought for less than $30 (here in the U.S.) plus half an hour to swap it around at the most beats the value of time involved into swapping a CCFL. Now, if I were looking into a bulb swap on rare QXGA screen or had absolutely nothing better to do (the latter is impossible to imagine, but just for argument's sake) I might take a different perspective.

All of that said, it's your LCD and your time we're talking about so proceed as you deem fit by all means...my previous post was written in order to prevent aggravation on your end, not cause it.

Good luck.

ilakast · #18 Post by **ilakast** » Mon Mar 11, 2013 2:40 pm

We have exactly the same LCD

Instead of sending you an email, I will post here various relevant things, that are actually from older posts. There is a huge amount of information that unfortunately cannot be neatly organised, so if others try the same, they could be spared from searching.

Regarding the possibility of getting a new/used LCD panel, take a look here and download the link to a Samsung panel pdf. Page 13, bottom is the theoretical schematic of what your (and my) culprit is. If I read ziemeck's post correctly, there might be a possibility of actually finding a compatible LCD even if it is not an IBM part, but I'm no expert (and always prefer the diy route).

Since you've read my previous posts, I'll just add some extra info (and a link to some photo instructions, although none is from our exact panel type).
Make sure you've got a multimeter with a continuity tester and use it to test that your pink and white cables do not short circuit with the casing, before you fire it up. If you have to rip apart the white plastic caps from each end of the lamp to get access to unsolder the tips, then when you re-insulate the ends with eg. insulating tape it is very easy to overlook a short circuit, because space is tight. In fact, space is non-existent. Everything fits by the inch, there's no play at all.

Another point worth mentioning, at least from my experience, is that - as you mentioned - the inverter gets really hot (see above pdf: pink cable) thus the pink cable is most likely been weakened and might break off shorter than you need to solder back on the new CCFL. There's nothing to do to avoid that if the cable is almost falling apart, but if you keep that in mind before attempting to desolder it, then you might cause less damage to the cable.

Good luck.

I refuse to work on ANY Samsung screen under ANY circumstance.
Actually, I refuse to work on ANY size screen other than a 15", and then only on a very limited number of brands, and again with the exclusion of Samsung!
And I have probably done more CCFL-swaps than anybody else on this forum with the exception possibly of Jamiphar, who does this for a living! (I don't)
And I'd love to join George/ajkula66 on his trip to find Nessie!

Cigarguy · #20 Post by **Cigarguy** » Mon Mar 11, 2013 2:58 pm

I'm probably sadistic enough to find a broken screen to tinker with it. Worse that can happen is I'll break it even more. Some may call it a waste of time but for me, the learning experience is worth it.

"While your LCD is as good as dead right now, the chances of you breathing new life into it without making it actually worse in other respects are slim to none. "

Maybe so, but since it's as good as dead anyway, and I enjoy things like this, what do I have to lose? Nothing. What do I have to gain? At the very least, I get to see the insides of something up close and personal, that I find quite interesting.

Blackstuff, as I don't have to do this stuff for a living, I can indulge myself and have fun.

ilakast.
Thanks for that informative stuff. I'm still digesting it. I downloaded the Samsung manual for the 15", and also found the one for the LTN141XA-L01 http://www.nhl.pl/index.php?act=attach& ... st&id=6116

I'm trying to get my head around the requirement of flashing the EDID. Just to confirm I understand that. ----

Even if I get a Samsung LTN141XA-L01, unless it ALSO has the FRU number linking it to MY T60 with FRU 13N7051, then it won't have the correct edid table, and might not work properly and might damage the mother board. ---- .

Is that definitely right though? I've spoken to several people who supply these screens now, and they tell me that as long as the revision number of the screen is correct, it will work correctly. Who's right? I won't take a chance though, and am looking for a new one with a FRU number.

Also, the link you sent to the pictures on the lcdparts website, is FANTASTIC. You said that although none is from our exact panel type -- . Actually the pics I found there are based on the exact same screen -- LTN141XA-L01, and there are a load more panels there too. Just scroll down the list. Maybe they only recently added it. Anyway, they make it look pretty straight forward (no doubt it won't be). But I'll give it a go. Thanks for the heads up on the soldering and the weakened pink wire. To avoid that, I may pay the extra and get the lamp with the wires already attached. about £18 vs about £12.

Wrong EDID info (or a blank EDID found on generic panels) won't blow the board, but will produce no image on boot. A wrong pinout can - and likely will - blow the fuse on the board.

You need to save (or locate elsewhere) your current EDID and flash it into the new panel if it doesn't have the FRU number. Mind you, any other panel used in T60/R60 will work as well, it doesn't have to be the exact Samsung one that you have now.

EDID flash is normally performed within Windows.

Screen suppliers are generally clueless about specific requirements that are related to certain ThinkPads...

slaterlp · #23 Post by **slaterlp** » Tue Mar 12, 2013 8:26 am

Thanks ajkula66.
I'm not sure if I fancy trying to write to the edid, but I'll read about it and see if I can interogate my screen as you say to save the table. Something new to play with. I'll download the appt software and have a look see if I can understand what to do with it.

I've been offered a FRU 13N7055, which is it seems a BOE-Hydis screen. I've been reading that the Samsung 7051, is better than the 7055 hydis HT14X14 version. Something to do with borders and contrast. Would anyone happen to know if I'd notice any difference? Which is the better screen, Samsung or Hydis?

ajkula66 · #24 Post by **ajkula66** » Tue Mar 12, 2013 8:45 am

I'd take the Hydis panel since the Samsung one is by far the worst of them all IMO...

Well this gets murkier and murkier, re the subject of compatibility.

I've now been told by 3 separate wholesale suppliers, and 2 guys that fix laptops and lcd screen featured devices in general, that as long as I get a genuine samsung LTN141XA-L01, it will work in the T60 I have. I've been told that the FRU number 13n7051, specifically refers to the samsung LTN141XA-L01, just like the FRU number 13n7055 refers to the BOE-Hydis HT14X14 screen, but that doesn't mean I cant order one of those screens by the makers part number. In fact, I was told it is quite the reverse. As long as I know the maker and the correct part number, I can order the correct screen, if I want the exact same screen, irrespective of the FRU number.

I was told that a samsung LTN141XA-L01, is a samsung LTN141XA-L01, is a samsung LTN141XA-L01. Lenovo don't alter it when they get it from Samsung. As long as it is genuine, it will work in a T60, if that is what was in there to begin with. The Samsung part number LTN141XA-L01 tells me all I need to know, -- I'm told.

The problem seems to be when buying, when you are offered a "compatible" screen. So even if you order a samsung LTN141XA-L01, that might not be available, and thus you are sent a screen with the same resolution, size, brilliance, contrast etc, but not necessarily the same make/model as the one you specified, and hence it may or may not work correctly. This is because the ACME xyz version 3 that you've been sent as a compatible screen, might be the same size, and res, and pin out etc, but might have other subtle differences.

But, as long as you order, and actually receive, a samsung LTN141XA-L01, then it will work perfectly well, even if it doesn't have the Lenovo/IBM FRU number on it. This is because, I've been told, Samsung and the like, make screens for many different manufacturers/platforms, and the exact same screen often features in a lot of other laptops. They don't always make a screen specifically for IBM/Lenovo for example, instead the exact same screen is sold to a lot of laptop makers. If they customised each screen for each laptop maker, not only would they become more expensive to supply, but it would cause a great deal of confusion not knowing which laptop a particular screen went into, because they would all have the same part number.

Hence if I buy a samsung LTN141XA-L01 it will work, because all samsung LTN141XA-L01's are the same thing.

Apparently Dell fitments are the exception, because they do revise the firmware, but Lenovo Tpads, using the samsung LTN141XA-L01, use the screen just as it comes from Samsung, and without modification.

Would anyone who knows please explain why this is not the case, if it turns out that I've been told a whole lot of hooey..

Thanks.

Hogwash. You might get lucky, and get the screen to work, but every major laptop manufacturer has their own proprietary firmware flashed, and this has been a SOP for at least the past 6-7 years...

Apparently Dell fitments are the exception, because they do revise the firmware, but Lenovo Tpads, using the samsung LTN141XA-L01, use the screen just as it comes from Samsung, and without modification.

The screen is the same. The firmware is not. Never was. Period.

Plenty of explaining has been done in this thread, at least on my end...you'll do what you want to do, and that's it.

I do hope that you end up with a working machine. I really do. If you were any closer, I'd ship you a working replacement, with a FRU number, for free...

Good luck.

If you were any closer, I'd ship you a working replacement, with a FRU number, for free...

And if you were closer, I'd take you up on the offer of the free screen. I'd even pay the postage. Now that's a thought. If you send me a free screen, I'll pay the postage.

Well, ---- Some people may or may not believe this, but,---

Following the excellent pictures here, http://www.lcdparts.net/howto/instructi ... N141XA-L01 as posted by ilakast, I was able to remove my ccfl intact, and without breaking anything. It took me about 5 minutes max. I'm no genius, so I can only conclude that it's extremely easy, -- when you know how, guided by pictures.

I'm absolutely amazed at how thin the tube is. It looks just a like a miniture flourescent tube. And it's blackend at each end, just as someone said it would be. The chap from backlightweb I think it was.

Anyway, I'm going to order a new tube and see how I get on.

Loooking at mine, I might be tempted to buy the bare item without the wires and save a few quid. Tight wad that I am.

I'd post a picture, but I don't know how to do it. And anyway, all you'd see is the same as in the link above.

As a test, could I connect the bare lamp to the inverter, just to see it outside the LCD? Would it work, or does it have to be contained in the lcd assembley to stop it breaking or rupturing or something?
