    the link took me to a site to purchase the service manual and the resistors look as though they will need to be soldered in

  • Gail White May 26, 2008

    I'm glad you have faith in my soldering abilities. Aslo there are no 3.3ohm 1/2 watt resistors listed. Only 3.9ohm 1/2 watt

Your convergence ICs need to be replaced. Please let me know the model number of your set and I will post the correct ICs for your model and where to get replacements that come with instructions on how to replace them.

    Your model uses the STK392-110 convergence ICs I would also get a couple of the 3.3ohm 1/2 watt resistor also just incase as that model will sometime burn on or two of the 3.3ohm when the ICs fail. This is an easy repair. Heres where you can get new ICs and resistors plus free instructions and online tech support by instant messageing.

    Yes they also sell the convergence ICs you need under the convergence IC section on the left side of the page. They do need yo be solderd but its basic soldering skills nothing technical at all really.

    They dont list all the resistors as the 1/2 watt ones are all the same price anytime I order I just send them an email first asking if they have the right resistor I need and they send an email right back indicating that they have placed the resistor I am looking for onto their front page. Try leaving them an email. they man the site 24hrs a day so they respond quickly.

What you described sounds like a convergence problem. When convergence has failed the colors will commonly look 3D,warped, etc. This tips page here on Fixya has more details.

The red in the picture is shadowing the rest of the picture giving it a 3d effect


All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. In some cases the TV will also not show any video. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....


  • Screen looks 3D, wavy, or has a shadow or shadows
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common 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.

I have a prjection tv that has a red color that doesnt line up and appears to be warped


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
*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

54" Projection TV


Your green gun in our tv is misagligned/out of focus. Your tv uses red, green and blue guns that layer in different shades and mix to create the different colors. Your green is a little off so the colors aren't mixing right which explains the green haze and the shadows. A tv repair man can fix this problem pretty easily and it isnt expenisve.
