My AOC screen goes black after about a few seconds after booting.

More than likely, you have set the resolution too high for the monitors capabilities. Set the computer to a lower resolution, and try again. If using windows, try to boot in safe mode to accomplish this. Other OS's can take variables at boot also to do the same. You'll have to search for yours.

Good luck.

old monitors all made before mid year 2010
are all CCFL backlamps and most died 5 year old
10/hr. per day and EOL hits..end of life.
the problems is not the cure we well know the problem is econ101
spending $200 to fix a $20 dead (sold for parts0 monitor is bad econ.

3. goES dead
4. goed dead only hot or cold (yours fails warm)
5. goes yellow tinged for pure white.
6. IF 2 TUBE BANK OR UTUBES, 1/2 GOES DEAD.

RIP one more of millions now dead, most are, unless hanger queened (nos) or was in sleep mode most of itS life,
at 20k hours of real use they die. (MEANS GLOWING)

Is the cable working? try reducing your laptop screen resolution and connect to your monitor. Your monitor may not support full hd resolutions....

please reset your computer or update your computer bios

try looking for bloated caps, check all diodes... see if its not shorted/leaking and finally check the power regulator ic if its not shorted! note: some capacitors and diodes are very tiny, you should use a lens with good amount of light...



if it does not help..... well, what the hell? try pouring some gas, then light it up! that should solve the problem, at least it turned on right? hehehehe!

I've had a very similar issue on many Dell Monitors. Mine have been under warranty and they usually send me a new monitor, but I believe the issue lies with the power supply within the monitor.

YOU HAVE A DRY SOLDER PROBLEM, You have to open the monitor and check the solders in the PC BOARD , mainly where theres A SMALL transformer resolder it , and try again ,that should fix it . hope it helps
