Here are the facts:
My TP T41 LCD is dark. Shine a light on it and you see dim video.
When plugged into an external monitor I have a Great picture. (Indicates a good video chip)
I took the entire panel off and put in on another T41 and it works great. (indicates a good LCD, inverter and backlight)
Re-install on original laptop and it's dark again.
When I hold my frequency meter near the inverter there are no oscillations, on the working system I measure 68.2 Mhtz.
If I manually operate the lid close button, both the LCD and external monitor go dark. I release the button and the external monitor returns to a nice bright picture. The LCD returns to the very dim picture. (indicates a good lid switch and proper sleep functions)
I'm STUMPED. Anyone have an idea?
Thanks!
