Hi! Thank you for using Just Answer today! My name isXXXXX am happy to help you with this! Please bear with me and be patient as sometimes these issues take a little bit of figuring out before we know what's wrong. If you could give me some more information it will be very helpful: -Are you able to get me a picture of the problem? (if you can post a picture, please click the icon above, where you are typing, of the paper clip. This will allow you to upload a picture) - Do you have this problem while watching all different devices hooked to this television? (DVD player, cable, satellite, game counsel, etc.)
Please give me this information and I will be happy to assist you further. Thank you, Tim Nolan
There are a couple of things that could cause this, unfortunately there is no reset for this television other than unplugging it. It will have an internal failure at this point. I will try to explain the possibilities the best I can.
First, this could be the main board, this would not be good news because you could be looking at around $300 for the repair (I know this is up there in the price range and most likely getting over what the tv is worth as far as repair goes)
Also you could have a problem with the panel itself, this would mean a new set for sure because the part cost is more than a new set. The panel in your tv is about $800 just for the part.
Any of these could cause your problem, but it will require troubleshooting to determine the exact cause of your problem. If you have experience, and test equipment and would like to attempt some troubleshooting I will be happy to assist you, however if you do not have equipment or experience then you would need a repairman at this time to get an exact diagnosis. I am sorry that I don't have a quick fix or easy answer for you on this one, it is definitely an internal failure.
If you would like any additional information or have more questions please don't hesitate to ask!
