Hi!
Recently the LCD of my T60 (2007-F4G, 15" SXGA+ screen from LG/Philips), developed a whole bunch (20 or so) of defektive (mostly dark, one green sub-pixel) pixels within a ~2/3" wide vertical stripe, running from the buttom to the top of the right side of the screen. On ebay I stumbled upon a 15" UXGA screen that comes from a T42p.

I tried the search function but didn't find what I'm looking for to answer my question, whether or not this screen could be used as a replacment. Or, in other words: what screen can I use at all to replace my current screen? I have no problem swaping the LCD, thanks to the nice manual from IBM/Lenovo.

More questions: would I need a new/different inverter? Would the inverter of the T42p's screen (it's the whole thing, including the lid, fully assembled) fit?

I've shot a photo that seems to show all kind of dust/smear plus something that looks like a tiny hair(!), but in fact this is the screen after I cleaned it (and of course it's not the lens of my camera).

Hopefully these are no hard questions to answer. Thanks for your insight!

regards,

Kai-Uwe

The inverter and cable on yout machine will work fine. The T42p is probably an IDTech brand. If it is it will work if you flash the eeprom with the contents from a T60 IDTech panel. If you don't flash it, it will not work and it may blow a fuse on the motherboard.

richk, thanks for the info. So I'd need the mentioned screen of the T42p to be attached to a machine it will operate at/with in order to be able to flash the EEPROM and I'd need the correct contents to be flashed into it, right? I could buy a T42p/43p for cheap. Would it work to flash the EEPROM while operating that machine or what else do I need?

I don't know how reliable the following site is, but I came across it while looking for compatible screens:

The only UXGA ID Tech panel put into the T60 is the N150U3-L01, it says. Are you saying this panel contains some type of ID Tech specific "firmware" that will work with the panel I want(ed) to buy, and is needed to be flashed into this UXGA panel of the T42p? Where can I find infos on the exact procedure? Thanks again for your efforts!

It is a lot of work if you are only dealing with a single panel. I flash them when they are not in a machine. I have a hardware interface that connects to the lcd connector and also connects to a second machine. The interface powers the chip.

N150U3-L01 panels are used in both T42p and some early T60p machines. The only dfference is the contents of the eeprom. PM me if you want to discuss more.

it shows a simpler method of flashint the edid using soley software.

I think that approach leads to a cooked T60. You would need to have the screen attached to a T42/T43 to get it to start.
