Problem is called convergence; see attached photos.

This set uses 2 of the STK-392-110 convergence chips, both will have to be replaced and total parts cost on EBAY will be under 25 dollars.

The good news is I have start to finish step by step instructions for this repair in this set. They tell you everything you will need and exactly how to do it.

They are based on my experience doing this repair in hundreds of sets just like yours.

I will enclose also a photo of what the chips look like.

If you want the instructions let me know and we will find a way to get them to you for free.

If this information told you something you did not know, rate this solution as I do this here for free.

This is a JVC board but it uses the exact same chips (black) that are in your set.

I tried the reset factory but it didn't work. I have tried changing the tv input but it doesnt work all i can hear it the white noise until i reach the input and i can then hear the sound of the TV but i cant see the picture. I oppened from the back i i saw 3 lamps on the bottom. They are all glowing but that about it. Has anyone had the same problem? PS I tried to put the tv on a table so i was taller but i couldn't lift it allt he way because it was to heavy. ALL i did was lift one side about 30 degrees and put it gently back on the floor. Did i screwed something by trying to lift it from one side?mment

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

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. 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
  • 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.

For more more examples and find a fix using this link on Fixya http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

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.

Having double vision different colors. Looks 3D.


Your Convergence IC's need to be replaced. A service man should be able to do this job in your home for about $250.00. That's the going rate at this time.

My rca projection tv has blue and green images like a 3D picture would without your 3D glasses, a double vision image and no other colors


sounds like the sensors are out of focus and your red sensor isnt turning on. look in the back of the tv for a master reset button or in your menu screen some sort of "Flash focus" or "convergence". They will realign the 3 sensors.

When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu.

Here are some photos of convergence problems.

e87380c.jpg
Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

69189a5.pngCONVERGENCE SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.
