Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

SOURCE: NO PICTURE CAN HEAR SOUND BUT SCREEN BLACK

If the picture faded over time and then went out completely....you have a bad digital main board. Hope this helps.

SOURCE: horizontal half black screen, sound is still there

A plasma screen uses thousands of tiny fluorescent bulbs in different colours (red blue and green) to produce a picture. Just like standard house hold fluro lamps, these tiny bulbs use starters to turn them on and off. As there are so many bulbs in the panel and therefore starters, the panel has a number of "starter controllers". These controllers can control anywhere from a quarter up to half of the screen. If a controller dies, it takes out it's segment of the screen. Unfortunately, it sounds as if this is what has happened in the case of your LG - this is also common in NEC and Fujitsu panels. Althought these controllers can be fixed, it usually takes more time and money than it's worth- unless you have it under warranty in which case the manufacturer will just replace it. Sorry top be the bearer of bad news. hope it helps

LG Tv M227WDL HDMI black screen


If the HDMI input is failing you will need to ring Customer Support or Get a New TV because if its not outputting then The HDMI may not get Prosecced (sorry about spelling) And make sure you have checked its the Correct port and that there is no Blue-Tac or dust in the port ( that ussually solves this) If all else fails Use a Hairdyer and give it a Big clean :D

Darn, that sounds like a time machine!

Whatever it is, though, it's hardly related to the TV if it only shows during movie playback and not in live TV.
