Having problems with your ViewSonic VA902b 19" Monitor ?

Screen won't stay on

\015 I turn on my computer and monitor but the monitor only comes on for a second, the green on lite stays lite but nothing on the screen ? bad capacitor maybe?\015

Answers :

This is a common problem with LCD monitors after a few years of use. The capacitors in the power supply board start to fail and this prevents the monitor from starting up correctly. Sometimes you get a picture and then it goes black. On some units you can keep pressing the power button and after several power up cycles the monitor will work until you turn if off. These symptoms are all common with capacitor failure. The monitors are well out of warranty now so Viewsonic will not cover the repair cost. But the repair is very easy to do yourself. You just have to replace the 6 power filter capacitors on the power supply board. Here is a link to additional information on this repair.

I hope this helps, I have repaired over 30 of this model with the same issue.
