Try your monitor on another computer, just to make sure it's the monitor and not a video adapter problem in the computer. It may be possible to fix it if you can find a reliable computer or TV service shop nearby. However, the cost may not be worth it for a 2-year old monitor. Unfortunately, the best solution is probably to buy a new one. : (
The green power light indicates that the monitor is receiving from the
computer correctly. I suspect it is going into high voltage
shutdown. There is a safety circuit that monitors the high
voltage and shuts the monitor down if it sees anything amiss. So
the monitor comes on and then shuts off. High voltage problems
are generally not worth trying to repair. Another example of a
worthless safety feature. High voltage failures are not
dangerous, and adding the safety circuit just kills the unit when it
may have some life left or worse, sometimes it is the shutdown circuit
itself which fails!
Hope this helps.
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 most probably cause by one or more Faulty Electrolytic Capacitors, I find these are the MOST commonest form of "Fault" in these LCD's TFT's units. I ususally simply replace "On Spec" all High Value Electros, in fact ALL Electro's are suspect and often I just "Shotgun" and replace 'em all. Usually fixes all problems. Always use High Temperature Caps. Try this as it is a common problem I find a lot. Good Luck.
