    OK,

    Then noise would be spark of high voltage wire due to lose fitting, coming from flyback and going into high voltage block.

    Only electric spark can produce such noise which affects TV as VCR tracking noise.

Could be anything in the high voltage section of the set going bad caps and bad soldier on fly back can also cause this to happen.
set needs to be checked out by a tech.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as 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. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

What you will need to do is convergence. You can get a repair kit from TvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.

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.

Screen role red and green wavie lines.


Hello dctc1,

Looks like there is a problem with the convergence IC's. You will have to replace both of them. I would also look for busted capacitors around the IC's.

However, if you are not familiar with TV repairs, I would advise against opening up the set. Best get a service man to come and diagnose/repair the set.

Hope that helps!

Seems two be out of focus with green and red blurr.


The convergence board is what is bad, the Convergence IC need changed out on the convergence board, or the convergence board itself, and you you can also check for blown fuse on the convergence board. The repairs are going to run around 450 on getting it repaired. The red, green, and blue color are alien through the menu, but if they don't line up, it needs repair.

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.

Red blue and green projector lamps not lineing up on screen


Cover any two of the lamps first and focus the uncovered one. Then be sure to adjust the electrical focus of the same color. Then move to the next one and so forth. At its best you will have to decide which color is off convergence, and that one will be moved a bit out of focus, in this case the optical focus or electrical, tweak and you shall receive. Good Luck...

It sounds like you are going to need to have the convergence IC's replaced. Not really a hard job, but the job requires the proper tools, soldering skills, and a service manual to get the proper part numbers and to perform convergence alighnment in the service menu after the IC's are replaced. Good Luck
