Question about Sony KP-53V80 53" Rear Projection Television

1 Answer

The color keeps going out

I Have a Sony KP-53V80 and I took in a month ago because the red on the tv was sticking out and there was a double picture on it. The flash focus would not clear it up. He fixed it for 300.00 and now the green on my tv is comming out with a blurry picture and double picture. I asked the repair man last time if there will be any other problems and he said that it is fixed. Please help and should I get mad or not

The repair tech used cheap parts or did not replace both convergence chips.


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 directions your convergence chips are bad and should be replaced. This is a commonthe color keeps going out - 2c07611.pngbr />

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.

Picture the color keeps going out - 578ba6c.jpgat needs the fluid changed.

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.

Model kp-53V80 has no picture and red light is blinking


the red blinking is the set trying to come on but not making it.

Let me be honest here, this set is way too old to be repairing as many major parts for it are no longer available, my advice would be to retire it and buy a new set.

No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted.

Sony big screen tv model# kp-53v80


It can be just an adjustment of your screen control. There is a "sweet spot" on the control where it allows the picture to come through. This is a common problem with sets that are getting old. If there is a problem with the high voltage from the color tubes then it will shut down the video until the problem is gone and it is safe again to show the picture. This is known as going into a shutdown procedure to protect the set. A technician will be needed to fix your problem since it will require proper troubleshooting and knowledge of high voltage system and safety procedures.

It's not a digital hi-def tv, so you either need a cable/sat box..or a converter once hi-def goes in and analog stops.

Heres how you get into the service menu. BUT be very careful write down anything that you change as this can screw your set up and if you write down everything you will be able to change it back if it affects your set. You may want to consider getting the service manual which will explain all the details on the convergence adjustments. If so let me know and I will post a link where you can get one along with free tech support to help you out with it.
Put the TV in Standby Mode.
  • Then press the following buttons on the remote:

    {DISPLAY} {5} {VOL+} {POWER}
    or
    {DISPLAY} {5} {POWER}
    or
    {DISPLAY} {5} {PICTURE} {POWER}
    or
    {DISPLAY} {5} {VOL+} {PICTURE} {POWER}

  • The TV will turn on with the Service Menu displayed.

  • Use numbers {1} and {4} to select the item to adjust.
  • Use numbers {3} and {6} to adjust the value of the data.
  • Press {MUTE} then {ENTER} to save new settings.
  • The words "WRITE" in red will show up in the upper right corner if saved.
  • Turn the TV off to exit the service menu.
