Screen goes blank within 1 second of being turned on

Very typical of View Sonic. Sounds like a back backlight or inverter. I would go to www.viewsonic.com and open up a RMA. Most view sonic screens have a 3 year warranty. They will repair at no cost ..(if it is within that period) There is a date code on the back of the screen that will help you validate the above information.

replace the logic board, not the power supply board. you can find logic board on ebay as low as $29...

You most likely have a capacitor that has changed value. When a capacitor goes bad it will work after it heats up. Sometimes a bad cap will have a bulging top or show signs of leakage. Sometimes can only be checked with a meter.

it looks like the Inverter's gone in your screen, it works like a starter in a florescent tube, it 'kick starts' your screen to come on. Turning it on/off many times eventually 'kick starts' your screen and makes it come on eventually.

The light turning to orange means the monitor is not getting a signal from the computer. Check your monitor cable at both ends and make sure it is in very tight and secure at the computer end as well. Also check to see if the computer stays on when the light goes to orange on the monitor. The power cord for the computer might be loose.

What your both experiencing is a slow degradation of the inside light bulbs. Just like what happens to regular fluorescent bulbs, they slowly flicker out.

Best to buy a new monitor.

Take apart your old one, you'll find burnt out bullbs on the upper and lower chassis deep inside.

it sounds like a backlight problem either the bulbs or the inverter.

The same problem w/ my viewsonic E70 17" monitor.The viewmeter or viewmatch color on screen do not appear when power ON, although the green led power is ON.

But if you rest your monitor for about 10 hrs or more the viewmeter will appear when you power ON the monitor.

You can now start your CPU.

Remember : No viewmeter screen on monitor when power ON, means no supply coming out the picture tube or high voltage.

But if there is Viewmeter on screen , this normal and OK>
