When it's turned on, the light on my monitor blinks but the screen doesn't display anything. Why might this be happening, and how can I fix it? Viewsonic VP230mb 1 week after warranty ended, the monitor quit. Power light comes on for about 1 sec., then goes off, no screen. Tried new cords, no luck. Hooked up another monitor and it works fine, so it is not a computer hardware problem. Got any ideas how to fix??????

SOURCE: Monitor Blinking

This is a Common problem MOST if NOT ALL, problems like this with this type of fault it is invairably a problem with the Power Supply, in the PSU Electrolytic capacitors dry out and often cause this type of exact problem... It is a relitively simple fix, by replacing the caps with new ones... Any good shop should be able to fix for a modest fee.. OR if ya know anyone handy with a soldering iron maybe they could do it for you there are generally about 4 - 6 to replace... in the PS section, just do them all to be safe

SOURCE: LCD Monitor has no video

Sounds your monitor has either blown a backlight or the inverter board is bad. Either way they can both be replaced, but tracking down the parts will be a bit difficult. But your LCD Monitor is in trouble! Sorry!

Blinking on and off is not always a capacitor issue, it is usually caused by faulty transistors at the high output transformers that light the backlights. Crappy board design ! But fixable in most cases.

I RMA'd this probablem as well. They asked the usual questions -- try it alone, check the connections, are you using VGA or DVI... blah blah. Eventually they could give me an RMA.

They have customer support via phone on Sundays in the US, which is nice. Total time from calling to RMA was about 20 minutes.
