I have an RCA 42" lcd full hdtv from 2010 and it turns on fine, the display works, but it does not receive signals from any input (dvd, game systems, or PC). I have tried unplugging it and replugging it and resetting it, it doesn't seem to change anything. What next?
Hello, my name isXXXXX can assist you. Seems like you have done a good job of diagnosing the Tv and with this information it means that your Tv needs a new Main Board. If you are good with hand tools and can be careful with the internal connectors then you can buy the board and install it yourself:
