T60/p QXGA questions

[spacejunk]

Chazz, I might have been unclear in my reply. You do not need the inverter for the reprogramming process but need a LCD cable to connect to the QXGA panel (not necessarily the one you remove from the UXGA panel of a T60P). I used a T43P UXGA cable I had laying around to solder the 4 wires for the reprogramming and didn't use the T60P LCD cable that I plan to use for the re-install.

Also if you mistakenly programmed the QXGA panel with a bad EDID you can always reprogram it again. I always do a dump of the EDID from the QXGA panel after reprogramming and verify every bit visually. Then I connect just the QXGA panel to the base and turn on to verify that it works before re-assembly.

I bought a QXGA panel and thought maybe I would get lucky as it says IDTECH/IBM on the back of the display. I installed it hoping it would work out of the box. No such luck. I ended up with a blank screen so it looks like I will need a cable and the programing circuit. Does anyone have one they would like to sell or rent? I would only need it for a couple of days at the most.

I finally got the picture and screenshots I took during flashing, and wrote some simple instructions.

Picture of the flashing interface borrowed from Troels connected to an old laptop (horrible picture quality): http://img30.imageshack.us/img30/5509/img0055fct.jpg

I don't know if this is the best way to do this, I downloaded some hexfile for an IBM-flashed panel and modified the resolution. As my panel was broken I just booted the laptop to see if it worked, and I saw the startup logo in fullscreen, and later the login screen, also in full resolution. I don't know if other resolutions work, or if there are any other problems.




Anyway, I wrote some simple instructions that should make the flashing very easy for anyone:

If you've never replaced an LCD before I recommend watching the video at http://www.lenovoservicetraining.com/io ... index.html
Just select FRU Removals/Replacements>LCD

1. Download PonyProg v2.07c and the modified hex-file (or Phoenix EDID Designer 1.3 if you want to edit something yourself).

2. Connect the interface to the panel and computer, make sure the port is activated in the BIOS etc.

3. Start PonyProg, setup and test the connection


4. Click "Read Device" to make sure you can read from the panel


5. If you want to modify something using Phoenix EDID Designer, or just want to have a backup (recommended) then save the file, edit it and then reopen it. Otherwise, just open the downloaded file.


6. Click "Write Device" to write to the panel, wait a few seconds and make sure you get a "Write successful" message.


7. Connect the panel to your laptop and reboot.

My panel had that text as well but still needed to be flashed.

As far as parts replacement you just need the QXGA panel. You can reuse the inverter card and existing LCD cable. For programming you need...

I noticed there are two versions of inverter cards available for the T60, one for XGA and another for SXGA+/UXGA. I don't know about any difference and they look identical, but as Troels had the SXGA+/UXGA inverter working with his QXGA panel I ordered one as they were cheap anyway.
