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.
Compaq TFT LCD monitor.

The backlight tubes or inverter are a common failure point of any type of LCD monitor. Replacement tubes aren't very expensive, but do wire them to the inverter and test run before you take the effort to install them in the screen.
