My Sanyo DP50747 plasma tv won't turn on. I tried plugging it up to another outlet, but still no power.

This unit needs to be tested in a service center because it has problems with the operation of the video card. This could be caused by a loss of voltage supplying the video card from the power supply card. Or a failure on the video card itself. You can purchase parts for unit from Best Buy Parts at !-888-237-8289 and get customer service at 1-877-467-8289. You should get an estimate from the service center, That should tell you which parts are bad and then you can proceed from there. If the prices seem too high for parts and labor from the service center, try buying the parts yourself and have them install them for you. You should try to check the prices on the parts , just to make sure you are getting a fair deal.You can do this by getting the part numbers, you should ask the service center to provide the part numbers needed if they need to replace the power supply board or video board and with your model number of television check out the prices and availability at the Best Buy Parts website.Of course if the television is still under warranty send it in for warranty service. Hope this helps you with your problem.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

Please post back what you find. It sounds like at least you do have the 5V standby power supply working but the main supply is not getting the 'ON' command from the main board, or the power supply is gettin ght e 'ON' signal but failed to turn on.
