I have a sony 60 in rear proj. lcd that has no red in the picture other than faint red vertical lines all the way across about an inch apart. any ideas ?

Hello,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER

Hope this will help out.....

I have a sony grand wega and there are red lines going vertically across the entire screen.

Well if the panel is bad it would not clear up in any situation, so its not the panel. most likely the t-con board or just poor connections inside. Julio Millenium TV in Las Vegas.

You have bad capacitors and possibly a vertical IC that is going bad. And check for bad grounds in and around the IC and caps!

bad lamp

Optical block or LVDS cable You need a tech to tell you for sure, have a tech look at it

Is there a cheaper solution? $600 sounds like you just throw it away to me...

Inverter board is bad or video cable loose either behind LCD panel or near video adapter.

My guess is that you're not missing the color it just appears muted... That problem is a common one in both the 50 and 60 inch models. And if you change video mode with nothing hooked up you'll see a faint color where none should be...
That's simply dust in the optical block on one of either the red, blue or green lcd panel. Wipe it down with a non-linting cloth and a "light" amount of windex and you're back in business...
But check it out by switchin through the video modes with nothing hooked up.. The faint color you see if the lcd panel that's having the most problem and the one that's muting your green.
