Re: PT-53TW5353

The convergence amps have most likely failed. Your set takes two STK392-110 Sanyo built Ics, Pansonic p/n# C5aa00000203.
They're located at board positions Ic7001 and Ic7002 respectively. In addition, you will need to test all the low ohm yoke return resistors in that circuit for change in value and replace any that don't meter correctly.
In the shop this is a relitively modest job with the most of the cost going to labor. I suggest, if you're going to have a shop do it call around and ask what they charge for changing the convergence amps and take the unit to them to save the pickup and delivery charges.
Good Luck!

Double picture and colors are neon green and pink

Your TV most likely has fone of two possible problems.

Problem #1 - Failure in the convergence circuits. ( 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.

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. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.


TV set after fluid change. Notice how bright the colors are now. Everthing looks crisp and sharp again.

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

Green and purple band of color

Projection TV sets have two very common problems listed below.

Problem #1) 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
*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

My toshiba tn61x81 projection tv

have you tried the convergence option in the menu? i believe it is under "picture". this allows for nine different sections of the screen to be adjusted when projection images get out of whack.

Panasonic Model No. PT-47WX42F

Replace the convergence amps. That unit takes two Sanyo STK392-110 and you could use 150's for greater reliability. Also replace one or more of the 1.2 ohm resistors in the yoke return circuit out front of the amps.
