Red CRT has died, or its drive circuit failed.

That model is famous for having CRT issues. Chances are the Red CRT or one of the CRT drive board is whats causing the issue. Usually if the set shuts down shortly after turning all red then its the CRT. But if it just turns red and keeps working it could be one of the CRT boards dropping out causing the Red to become dominate.

You may have a convergence problem (I will attach some typical photos).

When it does it go into menu and call up convergence grid--if lines skewed and colors mixed it is convergence. This model I think uses two of the STK-392-560 chips and both would have to be replaced if it is your problem.

I can provide more info if you find this is what you have.

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

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. In some cases the TV will also not show any video. 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, wavy, or has a shadow or shadows
  • 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 pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Hi,
If tv picture was fine before moved then check dry/ cold solder joints/ connections on convergence output ICs and nearby circuit area.
Local tv repairman will resolder loose/ dry solder connections to solve double vision picture problem.
TV worth fixing if picture is good.
Thanks.

These sets had a problem with bad picture tubes---it has a red, a green and a blue tube.

There is a way that requires no parts and about ten minutes to try to adjust for this, let me know and I will tell you what is involved.

The most likely scenario is that the CRT socket pins on that board need soldering. The board slides off the neck of the tube after loosening the fastener. you should see the solder cracks around the Socket pins.

Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.
