Screen won't stay on

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.

How do you fix the backlight inverter?

Hi...Guys,

Yeah...you're right! your backlight inverter are burnt out. Most likely due to over heating capacitors.
Good lucks!

I had the same problem and called Viewsonic (www.viewsonic.com). Bought mine in July '06 and to my surprise it's still under warranty. The warranty goes for 3 years so even though shipping is my cost, they'll fix or replace it with a same/similar model.

I had a chat session with Viewsonic and they agreed to fix all 4 of mine under warranty. No real hesitation on their part - maybe it's a known problem.
