7020...M # CM 870: Turn it on, the "Compaq logo" appears just for a
moment, then black screen. Place a light onto the front of the screen,
you can see all. Took it apart, all looked ok, soldered a few bad
connections, back together...the same. I didn't get into the
screen/lamps themselves, just the drive circuitry, & internal power
supply. Is there common backlight problems on this unit? Thanks.
