Unit turns on and displays Screen but then shuts screen but power light stays on. This happens all the time


The 12vdc AC adapter is putting out 12vdc when attached to the monitor?
The problem is more likely to be in the backlights inverter board, please check the fuses and voltage (12vdc) feeding the this board.

Hi i have a problem about my lcd viewsonic va702, when starting my computer i can see the image for 1 sec then it turn black ...lcd light is ok and computer too already tried with other lcd all works fine...


this works for Dell monitors with a similar problem: shut down, turn off monitor and pc, turn off at wall socket, and remove power plugs from wall socket. wait about 30 seconds. plug back in, turn on, and all should be well? I have used this 3 times on a Dell PC with a Viewsonic monitor.

My monitor goes dark after 1 second and won't come back until cycled off and on again


Hello,

It is the picture picture board on your monitor that is malfunctioning, since the power led or button is on, but the display screen goes blank after a second, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity or any service center to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

About a problem in my viewsonic monitor


Hi

Actually the common problem of viewsonic LCD monitor is bad electrolytic capacitor at primary, secondary & inverter area, if your lcd using power adaptor test the voltage out, use analog or digital tester range 50v dc, if the voltage out is accurate dont be sure to your adaptor working good, open it and find bad electrolytic capacitor inside. That is common problem of viewsonic LCD monitor could cause of display flashing then back to black after few seconds. Suspect inverter area lastly mainboard.

Gud Luck!
