Why is my refurbished Compaq WNG monitor going off?


From the description the problem is in the power supply board, there are probably one or more bad capacitors that have opened, sometimes they bulge at the top making it easier to spot. If you hire a shop to repair this they will charge, and on top of that the monitor is at least 5 years old before you got it, I would replace the monitor.

My Compaq 172 monitor won't stay on but for maybe 30 seconds then goes blank. When it does this, the on/off button is still lit up, but I have to lush it manually to get it back on for about another...


Failing Power capacitors. The capacitors hold the charge necessary to build up the voltage that lights the screen. When they leak or fail to hold the charge, the screen will cut out. It could also be a fault in the switch circuitry. Really needs looking at by a qualified technician.

Compaq 1720 monitor: the green light on the power supply went away, the voltage converter was very hot and the monitor went blank


You need to find out if the power supply is still putting out 12vdc, you may have to test it with a load (use 12v car bulb such as the brake lamp). It is getting hot can be due to bad power supply or too much load because of short circuits in the monitor. Please post back what you find about the power supply first.
