My 2379-DXU had a cracked screen, which I had replaced. However, now the LED strip won't light up - disk drive light, NumLock, CapsLock, power, etc. The only LED that's lighting is the wireless icon.
These LEDs appear to be part of the inverter card, so I bought a replacement inverter card and installed it, but no joy.

I removed part 92P6761, and replaced it with part 92P6680.
Part Number: 92P6680
Description: LCD PANEL, 15" SXGA+
Part Number: 92P6761
Description: LCD PANEL, 15.0" SXGA+
The strange part is that they don't appear to be sub parts of each other, even though they're both 15" SXGA+. Both are used in this model as well (2373).
I guess I need to see if I can get another LCD shipped to me.
I ran into the same problem when I replaced the panel on my T42. It turned out to be some pins that were pushed in on the LCD connector on the motherboard. How do I know? I tried the newly repaired lid on a second T42 and all of the indicators worked without a problem. Additionally, the indicators on the lid of the second t42 did not work on the first T42. I chalked it up to rough handling when attaching the ribbon cable to the motherboard.
The fix? I used a very, very fine needle to pry the pins back out and that resolved the issue. (This took a good half hour...and several needle pricks)
