Question about Sony KP-53S75 53" Rear Projection Television

1 Answer

Strips of color coming up from bottom of tv

When you are standing close to the tv you can see what looks like a red & green rainbow of faint color over the picture going up the center about 9 inches high. when you set back and watch the tv from a normal distance the picture is clear and the color is good and you do not notice these lines. tv seems to play good other than that. i have tried the flash focus for convergence and the crosshairs go back to form the white cross but if you check the next time the set is turned on you will have to flash focus again. the colors ar out of wack again. thank you

Youll need to replace the stk ics inside the tv. they are easilly found by looking for two larg heat sinks. im pretty sure sony runs stk392-510. you will have to look at the ics to verify.

My plasma tv just started having water colors flashing on top and bottom?

what do you mean water colours? do you mean like a faint rainbow type of thing, if so that means a magnet is or has been too close to the screen, and as far as I am aware magnet damage can not be repaired

Sony 60" HDTV Plasma WEGA....Picture Problem

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.

Faint lines show up when i get dark screens in movies

First check what color of faint lines comes then reduce Screen Volts in TV of that CRT (tube)
Take off lower front cover, speaker grille of TV, there you will see focus control block that has 6 control knobs, upper 3 knobs are focus adjustment of red-green-blue CRTs and lower 3 knobs are screen volt controls for red-green-blue CRTs. Turn screen volt control knob CCW to reduce screen volts of desired CRT.
Put TV on any free AV input so screen will be dark enough to adjust screen volts.

Sometimes I get a rainbow on the bottom of the screen.

Your TV most likely has a convergence 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 are some photos of convergence problems.

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 directions your convergence chips are bad and should be replaced. This is a common problem.


You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.
