No picture on mu LG television.


Try the old flashlight test, turn off the lights in the room. Turn on the set and flash a bright flashlight on the screen. Do you see the image or is the screen totally black?? If you see the image, then most likely you have a backlight problem. Verify that you have 24V on the power supply for the inverter

Axion handheld tv. No picture at all.


I have on and if the batteries start getting weak the screen display brightness is the first to stop working. Double check that, if you are on AC power try sliding the brightness control from dim to bright a few times and see if the rheostat has corroded. Those are a few of the quick checks you can try, let me know. Jay
