Question about Rosewill R900J 19" Flat Panel LCD Monitor
I have had an Acer 1913W for a few years and when I first got it, I had to send it to get the inverter fixed. It's worked fine since then.
A few days ago I cleaned the monitor through the vents with a really powerful jet of air (don't know it's the cause or a coincidence) and now if I leave the monitor off for a few hours, it won't go back on. It sort of stutters to go on and then goes black but I can still see the image with a flash light. If I turn it off and on a few times, it will eventually light up and will stay working.
Could I have knocked something loose inside with the air? Any ideas what to check inside to see if something needs to be replaced or fixed?
Could I have knocked something loose inside with the air? Quite likely

This model has 4 CCFl's and one of these bad will cause the inverter output to drop off.. (Safety feature).. easiest way to check is by process of elimination plugging a good CCFL from a laptop screen or similar inplace of the 4 to find the one dropping out. If all check good Check the Caps as these like to fail as well. Good luck!

I start my computer and turn it on, and everything looks fine for about 1/4 of a second and then it goes black while leaving the power light green. I can only see the screen again after turning it off and on, but that's only for another 1/4 second. What's up?
I got my rosewill flatscreen as a hand me down from my father. I've had it for several years now. Was working fine until a month ago. When I turn the computer on the screen goes black after 1/4 of a saecond. I have to turn it off and on anywhere from 10 to 20 times before it stays on. I have checked all plugs to the computer and outlets. I have absolutely no idea whats causing this.

This is very common problem and is heat/age related, but It can happen to monitors that are no more than a year old. It is usually bad capacitors on on power inverter board. I just fixed two monitors with this problem. This problem is common across all brands. Look for several radial capacitors in a cluster on the power inverter board. If some are bulging or have a slightly domed top, they are the ones that are bad. I usually replace all the capacitors in this small cluster because some may be marginal. This is easy to do if you have a bit of electronics skill.

well i have a dell 22'' monitor and it did exactly the same thing , turns out its a fault with the invertor drive transistors ( these power the fluro screen light ) , i'm in the uk , but i would take it straight back to walmart along with proof of purchase and tell them it dont work and ask for a repair /replacement under warranty
