Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
•Screen looks 3D
•Colors don't line up
•One or more colors can't be adjusted when using the convergence menu.
•Screen is bowed or warped.
•TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some photos of convergence problems

My Xbox 360 shows a grey screen, the sound works fine and i do have picture


Hey dude, I had this problem and found a solution on another website. Basically, I had either changed the display settings on my tv, or it had done it by itself or my new ps3 had done it or whatever, but to fix it I went into the TV menu, went to display options, on my tv it has something entitled 'Colour system' I changed that to PAL-60 and I now have colour, just to give you an idea of whether you have the same problem, try setting your x-box display to pal-50 and see if that shows colour (if it's easier to do), if it does then try then solution above! Hope it helps!

COLOUR PROBLEMS


Greetings!

This sounds like a degaussing (named after 19th century scientist Carl Friedrich Gauss) problem. This usually occurs one of several ways:

1. The TV fell down and went "boom".
2. Junior held a magnet up to the screen when you weren't looking.
3. There is a large, unshielded speaker near the set.
4. The TV was rotated in relation to the North/South magnetic poles of the Earth while it was running (yes, really).

All televisions have a degaussing coil built into them which is activated momentarily every time you turn on your TV. This typically will cure all minor anomolies over the course of a few days. However for a severe one like you have, it will probably require a trip to your friendly repair shop. I, personally, do not charge anyone to perform this service because it takes, literally, 5-10 seconds to degauss a TV. I simply ask them to remember me next time they go to buy a new TV or need service work. I can't say that your technician will do the same.

In the case of the first instance of the TV falling down and going "boom". If it fell with enough force to warp the shadow mask built into the picture tube, then all of the above information means nothing. The set will require a picture tube replacement to cure the problem.

Hope this helps,
Rob

Sony FD Trinitron Wega model KV-34BR800


Sony Wega Triniton KV-32FS100 TV

For the last week my TV has been going to a black screen for 10 seconds or so then the picture returns. It has been continual. Last night it stopped going to black screen, but now the standby light flashes 5 consecutive times and the color went haywire. A lot of red and everything that is suppose to be black is green.

I did a soft and hard reset with no success. What's wrong and is it worth fixing? Bought new in November 2002.

Big screen showing double and red ghost color


Go into your service menu and try to adjust the convergence, if it does not adjust, the IC's ( chips) are bad in that circuit. Call a local factory authorized dealer to service your tv. The cost should run around $450.00. Good luck.
