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

1 Answer

My Sony KP-53V80 has wavy lines in the picture, the color and color aliment is excellent but the picture has wavy or wiggly lines that move around vertical, horizontal and diagonally. Also when I’m watching it and a bright white color like someone wearing a white shirt or sunlight or a white car the lines intensify and make a static or white noise sound. I've also notice that one of my AUX inputs has lost the sound. Any help would be much appreciated.

The problem you have mentioned is caused by a malfunctioning deflection circuit and/or HOT(Horizontal output transistor). Note that replacing these component requires good electronics/soldering skills. I should also mention that the deflection circuit is a high voltage circuit(about 30,000V) and it is not recommended that you do it yourself unless you have worked on high voltage circuits before.

It is showing a double picture


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

There are wavy colored lines an the screen all the


A problem like yours is NORMALLY NOT the TV set's fault....it's the Cable.

I'll bet you see thin lines moving across the entire picture...they are slanted like this >> \ \ \ \
That's generally caused by a bad ground on the antenna cable OR it can be the cable box's MODULATOR.

Try using your VIDEO OUTPUT off of your Cable box and see if the wavy lines are still present. If they are the Cable box needs swapped with a good unit.

You can also verify this problem by checking your TV with a DVD player...no lines indicate the TV is fine.

If you have problems with the DVD player's picture, then you must have dried out filtering capacitors on the Video board IN the TV set...

And THAT is not an easy fix if you do see lines with your DVD player.

I have a Sony Projection TV KP-53v80. I tried to turn it on today bu there is no picture no sound. The Timer/Standby indicator flashes 4 times. What does this mean?


No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted.
Check IC1509, Q1505

The color keeps going out


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 common problem.

2c07611.pngSolution #1

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 of a set that 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.
