Recently, I aquired a 12" G4 Powerbook that survived being run over by a car. The only two casualties were the LCD and optical drive. So, I thought I'd just replace the LCD with a compatible screen purchased on eBay, and I'd have a great laptop for cheap.
I was wrong.
The LCD I took out was an LG/Philips SP121X04 (C2). I bought an LP121X04 (B2) off of eBay and plunked it in the laptop. The laptop didn't detect the new LCD. When I plug in an external monitor, I indeed see that Mac OS X does not see any display but the external monitor, even after clicking the "detect displays" button.
So, I did some more testing, tried plugging in the old LCD and hitting "detect displays". After the backlight lights up and a little bit of picture shows on the cracked LCD, I then pulled the 20-pin LVDS connector and plugged in the new LCD. Voila! Clear bright picture!
So, I know that the hardware is compatible, and in fact uses the same protocol over the LVDS connector as the old LCD. However, I am still unable to get Mac OS X (or Open Firmware) to recognize the new LCD.
Does anyone have any ideas about what is happening or how to fix it?
I'm running Mac OS X 10.4.5. The video card is a GeForce FX Go5200, with ROM Revision 2069.
