This manual may help.

The setting you need to change is on your sky box not the TV!

Most likely "AV Mode" button(has orange circle on it) on the remote has been put on wrong setting push repeatedly untill corrct setting is reached, I believe it will say "normal" or "standard" Hope this helps.

Check and replace the backlight inverter board.

Check and replace its T'Con board.

If you're trying to use it as a monitor, it looks like the HDMI port on the tele is not working. It could also be a faulty lead from your PC.

Hello,

The problem actually is from a lamp in the unit, it is getting damaged gradually that is why it is two third of the screen that has gone dark. once it gets completely damaged, the entire screen will turn dark.

Try to ***** the lamp of the television and replace it with a new one.

After doing that your television will be in good condition once again.

Take care and good luck

can get remote to controk all of my lg37lh3000 but not the volume have tried codes 2210, 1293, 1176 and a few others any ideas please, jan

Sky remote code for LG LH3000 is 0206. This works for the 37" and the 42" and probably for a plethora of other sizes.
