LG 42LH3000 Screen Problems	Can't Post

Hi all.

I have a 42Lh3000 LG LCD TV.

The screen has a tendency to show the picture in a negative image, or occasionally with a blue or red contrast to it. Alongside this, it has loads of horizontal lines going through it.

It occasionally sorts itself out and stops.

Is this a T-con board fault or the LCD screen that has gone?

http://i60.tinypic.com/n64x2b.jpg here is a picture of the screen.

Cheers Smile

As you post no pictures ... best educated guess:

'Negative image' (Solarized) usually = AS15 IC on tcon. Can't say about red/blue.
They say Horizontal lines are NEVER caused by tcon.

Would you say that was the Tcon then?

Cheers for the help.
