My Panasonic TH-P55VT30A has sound but no picture. Any suggestions on how this can be fixed?

@kerryn60 what exact model is your TV. Shine a flashlight at an angle against the screen. See if you can make out shadows etc. If so, it is your backlight that has failed. That would be a power board issue. Otherwise it could be anyone of the boards, most likely the power board or T-con board. You’ll need to remove the back of your TV and take a good look at the boards. Check for any obvious damage like domed looking or leaking capacitors etc. Post some pictures of your boards with your question. That way we can see what you see. Use this guide Adding images to an existing question for that.
