Envision Series / AOC 22 hdtv monitor

HI Fixya ,
First post ever.
I have a 22 inch monitor
AOC Envision Series L22W765, I believe its the model for Latin America.
Yes I went to the AOC pages here at fixya , but I couldn't find the envision model.

Here 's the problem.
When I turn on the monitor, it searches for a signal,the power light flashes orange , displays the computer or tv image and after 5-10 seconds it turns it self back off agian. The power light stays orange.
The problem started yesterday but after two tries it stayed on.I turned it off and in the evening it worked again. But today it just turns it self back off again.
Three days ago I Installed a soundcard , but after a few hours it was giving me feedback through the speakers which are on the floor. The mic was turned off by the way ,pc mic level and the mic itself .The monitor worked fine no distortion.Could this be the problem. How can I fix this ? I bought it 4 months ago ,it worked perfectly ,and I dont believe this models is that old. Or did some fuse get blown Im not a technician but I can ask a few people here to help me ?
Im really disaspointed right now
Thanks for your help

Probably blown capacitors, the 19" widescreen uses 6 16V 1000uF
Do you have a soldering gun? Its not that hard to fix, get the capacitors on ebay for $6-$8 with shipping.

When i turn on my monitor (Envision G22LWk) it will go blank about 1 second after I turn it on. What might be the problem?


You may have power supply/inverter board problem due to bad caps, or worst case will be bad lamp assembly, the one shown here has broken lamps, you can hear arcing sound if you listen real close.

I have an Envision LCD Monitor, model #H22W. It has a blinking green light but is not working. I have rebooted, unplugged, and plugged back in. Nothing. It won't even turn off. Help.


You need to try it with another PC first, but more likely to be bad caps in the power supply section inside the monitor.
If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.
