Re: WEGA KF50WE610 50 no red color

Hello ml707,

This could be a problem with the red video driver circuitry or the signal processor. The $1000.00 price range is rather steep, I say this because you can buy one of these sets for $1400.00 used from:

It is possible (the $1000.00 repair price) depending on if the lens is at fault along with other factors, Take into mind this is an LCD projection TV and the lens in this case is to focus the picture from the LCD screen onto the projection screen

I hope this helps,

Thats caused by a bad optical block. The cost of that repair will almost always be greater than replacing the TV.Thats a very common issue with alot of Sony DLP models which suffered that optical block issue with the blobs of color usually blue or green

There are some adjustments that can be made to align the picture. This might correct your problem. They should only be made by trained serv tech. If that won't fix it then replace the light engine. There are 2 different ones for this model. They are serial number sensitive.

Color problem with Sony Grand WEGA 42WE655


Well, there probably isn't any relation between the two problems occuring exept for the timing. Magnetism won't affect a rear projection LCD.

I would say that your description is a bit odd, though. Usually on this model, there is a blue blob that shows up, eventually turning into a blue haze, and a star pattern of stuck pixels. It almost sounds like you have a bad set of component cables. On the SXRD's, they usually turn green.

Does it do it on all inputs (including the channels)? If it does, then it is the optical block. If it does not, then I would suspect that it is cable-related. If it is the optical block, then there is no way that any input can be different from the others (except for digital/analog differences, but those are usually obvious with patterns vertically on the screen).

If it does not look the same on all inputs or channels, change out whatever cables you are using. A loss of the red or blue cable in a component can give the symptoms you describe.

I hope this helps you...

Colour splashes on screen.

the lcd panels in the optics block are going bad, getting dirty etc., the block needs replacing and will cost upwards of $750.00 total.
google sony optics for your model for warranty extension possibilities.

Red color is missing - everything is green

You will need the optical block replaced. Approximately $1000 or so plus around $400 labor and taxes. Visit Sony's website to see if they are still honoring the extended warranty for the optical block issue. They know it as a green tint complaint. The menus will also be affected if you have the problem.

If the issue is no longer covered, try negotiating a shared cost repair.
