@danielgaleboe you are in the wrong area. You will need to ask your own question instead of leaving it as an answer to some other question. Next, you need to be more descriptive. You will need to give the complete model number, what it does, what it does not do, what you have checked and what you have tried. That why we can all try and help you with your Plasma TV.
