Plasma Tv Main Board Repair Overview - Tv has audio but no video - Symptoms of a bad main board

I would like to say that if you are having a problem with your TV, be sure to check the model number first. You will see the model number and serial number over in a box like this. The model number and serial number are very important, because that is what will help you to identify what parts are needed to repair your TV. If you are having a problem with your TV, please feel free to comment in the comments section below this video or send us a message on youtube with your TV model number and the problem that you are having. This way we will be able to help you diagnose the problem and suggest a fix. So the first thing you are going to want to do is make sure that you have unplugged your TV from any power source and that you have also grounded yourself properly. Next, you will want to take out the screws in the TV that are holding the back cover on it. The main board, which is located over here, typically manages your accessory inputs and outputs and houses the TV tuner. So this controls, this is what sends the signal from your HDMI ports, your RCA connectors, your VGA input all your different inputs go through here and then are connected elsewhere on the board to get the picture on the screen. If the entire set restarts on its own without you doing anything, it could be your main board that is causing that. If you are having issues with the video on the screen, it could be a connection here or the main board that is not allowing you to have the full resolution or clear image. Again, if any of these inputs don't seem to be working with your TV it could be a bad connection here. The first thing I would recommend you do is take your source video, so lets say you have a blu-ray player connected to this HDMI port, take that blu-ray player and connect it to a different TV and make sure that the blu-ray player is working fine. If you then find out that it is working fine, and you connect it back to this TV, then you will know that the main board has a problem or this connection has a problem because the blu-ray player works fine.
