Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

  • 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.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directiMy panasonic big screen screen has shadows and fuz - 2c07611.pngnvergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


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.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Sounds like you might have more than one issue. Cleaning the mirror is just a matter of removing the top half of the back panel where the mirror is mounted and cleaning it. I'm not sure that will take care if any of the issues you described though.

Sony KP65WV60 CANNOT RECONISED RED COLOR AND WRITING FUZZY


First, try cleaning all your lenses & mirrors...THEN
considering the age of this unit, the red CRT is probably worn out. Weak CRTs are probably the problem with the fuzzy picture also.
You can try to adjust your screens (the screen adjusts are available by removing the bottom front) to bring in some red, and adjust the focus on each CRT for better focus. I'm thinking with the age of this unit you may need more than just the RED CRT.
If any parts are needed, My recommendation is to replace the unit with new technology. Would be more economical in the long run.

Its a slight possibility that a 2.00 Part called a capacitor could be bad on the screen drive voltage source. But most likly it sounds like the Picture tubes are comming to the end of there life expectancy. If the crts are weak there is a crt rejuvinator that could possibly clean the grids off each color gun. But this is a crap shoot, as sometimes it destroys the tubes. These type of repairs are not for the handi-man or a consumer to do. There are no real user replaceable parts inside so unless your able to solder and know the HI Voltage saftey issues, you should call a pro to assist you in this repair. Good Luck
