Question about Sony KP-53V35 53" Rear Projection Television

Open Question

Picture flips upside down and right side up, distorts

I am having problems with our Sony kp-46v35 (1996). The picture arcs, RGB stripes show in a bow at the top and the picture flips upside down and right side up continuously (sometimes zooms in too). The same result with all inputs. I was hoping there'd be some adjustment knobs on back or inside, but no luck. Dusting is all I can do. Any ideas? Barter available - Graphic Design for service on this TV (Sacramento area). Thanks. frank@prochroma.com

SOURCE: BAD PICTURE, DISTORED, MOSTLY ON THE EDGES, BUT THE BLACK LINE ON TOP IN HIGH DEF CHANNELS IS NOT STRIGHT ACROSS, IT BOUGHS DOWN LIKE A "U" SHAPE

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 directions your convergence 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.

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.

This is probably the notorious "light engine" problem that all of these Sonys of this design run into sooner or later. It is usually more expensive to repair that what the TV is worth, sadly. A Sony authorized repair center can confirm this.

Model kp-53xbr4ct made 1998. picture was good. sudden went to center of screen and bowed up and down from center. it hade sound. turned of, now no sound. stand by flashes 6 times. unplugged , plugged back...


the video color distortion with the bowing in the center is called a convergence failure. the 6 blinks indicate a power supply shutdown for high voltage protect. the 14 blinks is just the tv trying to turn back on. you may be having to problems with the convergence and the 6 blinks or it may be related because the convergence amps can cause shutdown if they are shorted. i suggest calling a serviceman per the possible tow different failures. good luck

56" sony rear projection picture problem


Projection sets have two very common problems.

The first common problem is convergence

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...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*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

I have a pic problem is it fixable


If the picture is bowing in on the sides, this is called a pincushion problem. Please confirm that your model is KP-53XBR45 and I'll look up the probable defective parts.
