I have a display problem with my 400 mhz Pismo. It works great with 10.3.9. When the unit is moved slightly or you tap on the top sides around the keybd and or palm rest, the backlight goes dim or it may go completely dark. I can still see the very faint image on the screen but with no backlight. If I tap it again it usually comes back. I've purchased a new flex video cable (the one that wraps around the hindge). I also swapped out the display, and inverter board but the problem still is present. I even went as far as to take it all apart to verify the connections to the mail logic bd. Any idea, tips or suggestions.
Thanks in advance
