15" T42/T43 (or T60) SXGA LCD upgrade for a cracked G40 XGA?

#1 Post by laboye » Mon Aug 10, 2009 4:20 pm

Hi everyone. I have here a ThinkPad G40 with a cracked 15" XGA LCD that I won on eBay. I'd like to know if I could safely order a T42/T43 15" SXGA LCD for use in this G40. Looking at the stock options, an SXGA LCD was offered for it. Would I need a new LCD cable or inverter?

Also, would a T60 15" SXGA LCD do the trick?

I haven't found the actual model numbers for the LCDs (IBM part numbers, aside), so I'm pretty curious as to the cross-compatibility of LCDs between different ThinkPads. Any help would be greatly appreciated!

Regards,

-Eddie

Wait till you get your G40, then post the manufacturer's part-number and the IBM P/N or FRU
And D/L the G40 Hardware Maintenance Manual for cable and inverter P/N or FRUs

You may have an issue there since G4x units were pretty much a world of their own...another unappreciated, unloved, outsourced-to-ACER child...IBM had quite a few of those, and not all of them were bad machines in real life...

Take a look here...

http://www-307.ibm.com/pc/support/site. ... 61.html#15

From what I'm gathering, you'll need the cable and inverter to match the SXGA+ LCD. Will a screen from a T4x or T6x work remains to be seen.

Good luck.

If I can make the time, I will dismantle the G40 and a 15" T42 with an XGA screen and compare the info I gather. I'll get back to you guys when I can. Thanks.

R30/31/32/40/40e...but not any of the R5x and later units.

Z series was also outsourced to a third party, but can't recall exactly who it was at the moment...

As it turns out, this machine had an SXGA+ LCD to begin with. It's IBM P/N 92P6668 and FRU# 92P6667, the same listed for this machine in the HMM. It is a Samsung LTN150P4-L01. The LCD cable is a 30 contact connector 1.25" in length (on the most narrow part of it). I took the 15" UXGA IPS display from my T42p and tried it in the G40 after seeing they used the same connector. It worked okay, aside from having a wrapped vertical image due to the resolution difference. The connectors were also in the same location. With these things in mind, I'm going to give it a go.

I would, however, like a broad take on the cross compatibility of ThinkPad LCDs. Would a T6x 14" work in a T42? Vice versa? An R52 LCD to a T40? I'm thinking of a nice, massive matrix but I don't have the data to fill it. Can anyone shed some light on this?

I think the Z series was the first 100% designed by Lenovo. I'm not sure about who constructed them, but Lenovo takes credit for the 'Z's.

Good to know. You will be building a G4x FrankenPad with an IPS LCD, right? :)

An LCD from a T4x will NOT work in a T6x, but the swap will work the other way around, because of BIOS/EDID issues on T60/p.

T4x and R5x are compatible. More on the LCD stuff here, mostly good info:

http://www.thinkwiki.org/wiki/TFT_display

I know that Lenovo takes credit for designing the Z series. However, I also know that there was a subcontracting issue with those putting numerous owners with machines still under warranty, in an extremely tough spot...

I see. I've also got some interesting news for you. I bought a 14" XGA LCD off of eBay for an unbeatable $32 and decided to give it a try in a T60 project I had going. It worked! Speaking of work... gotta go!

(...a few hours later)
The T60 I speak of took the 14" XGA LCD like a champ. I'll have to start grabbing LCD part numbers and swapping them out to check. If more LCDs are compatible with a larger variety of ThinkPads than once thought, it may mean cheaper screens for everyone (not being bound by IBM FRUs, etc.) This first struck me when I saw threads of people adding these crazy 15" QXGA LCDs to their T43ps, etc. :) We shall see.

Regards,

-Eddie

When next you have some time, please publish the LCD make, model # and where it originally came from (like a Dell D600 or whatever), that you put in your T60.

The G40 15" screen you have, is the same as used in the R40.

I might just do that, actually. My plan was just to replace the SXGA+ LCD it had, but I tested it with the UXGA IPS display in my problematic T42p (needs a reballing =( ). An IPS LCD would be awesome for a desktop replacement like the G series.

According to the auction, it's an LG Philips LP141X14 LCD Panel with IBM FRU#: 92P6726. From what I gather, it was the intended replacement for a T4x, R50 & R51.

I'm getting ambitious about making that LCD matrix. :D

EDIT: I'm running across a few well priced 15" SXGA+ LCDs for A3x machines. Some of them IPS displays. Any successful A3x LCD transplants to R5x or T4x machines? I see these models on those eBay listings: Samsung LTN150PE-L01 (FRU:11P8298), "ITSX95E-B or DP/N: 9H201", IDTech IASX12S (FRU:11P8206) to name a few.

Thanks, that was indeed a standard 14" XGA from a T40.
Here are some infos to help you start your matrix:

IPS LCDs used on A3x units (both SXGA+ and UXGA) were made by DBU and are in my not-so-modest opinion the warmest ones of all the FlexViews, but they're getting old and may need CCFL replacement soon.

Non-IPS SXGA+ LCDs were made by Samsung and are OK, as good as a standard TN panel gets.

That's true--the CCFL age factor. Are they physically and electrically compatible with T4x/T6x/R51/R52 machines, though?

Any updates on this project? I am following this with much interest. I gave an SXGA G40 to my father in law and a Flexview upgrade would be great. The current panel has very poor viewing angles.

From thinkwiki information, it seems like this should work. I.e. seems like the XGA lcds are electrically compatible throughout the A3x/R5x/T4x/G4x series. Would be nice to have a confirmation though.

This weekend I tried putting an 15" XGA from an A31 into a R50E. The connectors fit just fine, however, the thinklight cable was a big short. I was able to cut and then solder on an extension. Its currently installed now and working great.

I was successful in transplanting an A31 SXGA Flexview panel into the G40.

@vanaya: Is your current project the R51E listed in your signature? I have not been able to get my R51E to recognize anything other than an XGA+ panel.

The best I've found is this rather hidden page on ThinkWiki. It isn't 100% complete, but with a bit of CTRL+F, you can find matches. If I find good candidates, I suppose I will be contributing to this list instead.

@virge, yes but I think want to do a little bit more. I would love an sxga+ on my R40 15", but wifey has an R32 14". I have read some threads on emeraldgirl08 projects and thought it would be possible. So to say the least I'm a bit confused and without a direct plan.

What do you think about this thread Swap R51e LCD w/ R40 LCD

and R52 LCD Replacement Problem (SOLVED)

Now that I looked on Ebay and threw some cheap bids on some parts machines I have just acquired an R50. So now I'm definitely off course and hijacked another's thread. I will post a topic with updates as soon as I get space and time.

I think the BIOS in the R51E limits the machine to XGA resolution. R52 machines have similar hardware, but didn't have this limitation. AS far as I know, XGA+ screens are interchangable between the R5x and R4x machines-- this is emeraldgirl08 was able to complete the swap.

On a side note... I sent you a PM regarding a 15" SXGA panel for the R40.

Hi Laboye. Hi Virge. I was successful in transplanting an R40 LGPhillips (forget model no... it's in my old posts) into my R51e. I have not personally tried the Flexview but have heard from fellow forum members that it did not work. I'm also suspecting that the BIOS limits this...as to why I do not know why. The R51e was an economy designated laptop so I'm guessing they figure why add options for higher rez?

Have fun with your endeavors Laboye :)
