tv has sound but picture is upside down
i need help fixing my flat screen its picture is sometimes black or green or purple it even is upside down and backwards but other times it will work for an hour than go back to not working sound works great though. any suggestions??
There are a number of possibilities. The most likely is a loose connector within the television housing if it's under 3 years old. If older than that, there are a couple of connectors that are famous for aging and cracking at the solder joints. These can usually be fixed just by reheating the connection and re-flowing the solder. Both solutions require some time inside the housing.
