Hi I have a Panasonic TX-55AX630B - and I have the same issue green light comes on but no picture sound sometimes works - any ideas ??
‘’’++Dave Crisp++’’’ you do want to check your backlight. In a darkened room turn the TV to a station that you know is on the air. Then shine a flashlight at an angle against the screen. If you can make out silhouettes etc, it is your backlight that it out. Could be a power board issue as well as a backlight array issue. If you cannot make out any silhouettes and since you are also having trouble with the sound, I would check the main board. Post some images of all of your boards etc. with your question. That way we can see what you see. Use this guide Adding images to an existing question for that
