Hi everyone, I hope I posted this in the correct board. I’m Tony, I have an older HP 4700 Hd TV that has no display. When I turn it on, I do see the screen light up a bit, but once it’s on, there’s no image, I try to adjust volume, change source or even change channel and the screen remains black. This happened suddenly one night as I was watching television. There was no power surge or thunderstorms at the time either so I’m not sure what it could be.
