Can't get sound to play on my AOC LCD from my XP computer.
I have a Compaq computer running XP. Recently I installed an Envision Series AOC 15" monitor/tv (model A15X221). Everything works fine, except there is no sound. When I plug a set of head phones into the computer I get sound, so I am thinking that I need a driver for the monitor. Any suggestions? Thanks, Dennis

Did you have an installation disk?? If so it may not have loaded in the setting to make the sound card accept the monitor..Or simpler--is the right wire plugged into your computer for the sound??

You probably have a power supply problem. The electrolytic capacitors are a high failure item in these TVs. I just replaced two capacitors in the power supplies of my two AOC TVs and got both of them working again. Repair will probably be much cheaper than replacing the TV.
There are only two things that can cause this problem -inverter and T-con. Since you have already replaced the inverter, it can be nothing other than the T-CON or LCD controller. Replacing the same should resolve the problem. On a side note the inverter/T-Con problem can be isolated easily. The purpose of the inverter is only to light up the backlight of the panel. So when it fails you will still have a faint picture that can be seen if you flash a flashlight on the screen. If you would like me to find you the replacement T-con let me know the part number and I will get you the link to the part.
This is either a problem on the Power supply board that supplies the 24volts to the Inverter board or the inverter board my have a bad capacitor or two, or a bad transformer. It's difficult to say exactly without testing it.
