Thinkpads Forum

I purchased a spotless T60, with a LCD "issue" Its a X1400
Upon arrival, it powered up to a pink screen. It stayed pink, never cleared from pink.
Ordered a new screen and installed. Did not work. You could see the Thinkpad screen, but no back light.
Swapped the LCD, Swapped the inverter, Swapped the cable.
Pulled the CMOS battery, and the regular battery. Powered on several times without battery(s)

Still no back light. Im sunk correct?

Plug the original screen into the inverter and power up. If the pink CCFL still lights up, and your "new" one doesn't...you got an LCD with a bad lamp. Should be able to exchange it for another, if it's really new.

Tried that, [censored] thing wont come on at all now.

Ron

Oh! Must have blown a fuse on the system board...
You can check them with a multi-meter. Replacing one is much more of a pain, though.

Where would i start to look?

Ron

Not sure about the T60, but on the T43 I've repaired the fuse was very close to the LCD cable connector. Probably a similar arrangement on the T60. Most of the fuses will be labeled with an F# on the board.

Please tell me what indicators light green when you start your thinkpad.
I have 1 situation when i blown F8 (low voltage path to power bluetooth and invertor internals). With F8 blown only WLAN & WWAN indicators lights on.
It was on T61 mainboard - may be it helps with T60.
See pictures from my local forum http://forum.ixbt.com/topic.cgi?id=17:45740:2758#2758.

The T60 backlight-fuse sits immediately to the right of the LCD-cable connector.
Might look pale blue or green.
You need to get:
3 Amp Littelfuse 0466003.NR (used to be 434003, now obsolete)
You can get them e.g. here: http://www.newark.com/littelfuse/046600 ... st=86H2954
Solder it on top of the existing one.

I must have blown about 80 of them during my LED-mod testing period. All gone by now...

Fires up normally, every light is correct. LCD works fine, except no back light.

Since the board is a POS at this time, I see a single strand of wire and a little magic in its future!

Ron

You need to pull up the black plastic film, to get at that fuse.
On my test-machine I had removed that fuse and instead soldered 2 wires with a small crocodile clamp each.
Between them they held the fuse, which itself was 'stuck' in a small hole in a piece of plastic, to prevent the crocodiles from "meeting".
That way it took only a few seconds (and curses) to pop out the blown fuse and stick in a new fuse every time I had to replace one.

I did the same. This was T61 mother board (and it works fine right now;) and i was afraid that using hot gun or soldering iron can blow fuse when i try to reassemble it. I dont know what temperature i must use to solder it safely...

I took 2 single strands of wire, twisted them together using the S.W.A.G. method and installed the patch. Replaced the black plastic tape, and it fires up just fine!

Paid $29.00 for a 2007-???. Got it spotless and complete less the HDD. Included the HDD tray and spacers, 2 gigs ram and all kidding aside, its 9 plus in the looks department. Did i mention the Boes Hydris screen?

I Thunk I did OTAY!

Never ends, now I have broken the donor.

Geez
