The Y-Sustain PCB is Failing.

It will require replacing soon.

The PCB does have some adjustment pots on it, if you were to take the TV to a repairer they may be able to "adjust" the halo effect out.

But the board will still fail.

Last night we got some multicolor, green, yellow etc horizontal, kind of half moon shapes coming across the screen, removed the front screen and cleaned the lens's and mirror,, no change. Any Ideas?...


All 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.

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.

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.

No picture


Possibly but I will need a great deal more informtion... When you say no pic, do you have any raster, blue screen or any light at all?? Sound - when you change channels does it appear to change or stuck on the same channel? If you look across the screen can you see an image of a picture - use a flash light in same direction - any image at all??

Blurred TV - double vision with red hue


I was searching online about what could be the problem with our TV and I came across your page. We have a 52" JVC Projection TV that now has a "blurred" screen. We can see the channels but it looks like it's has a shadow around the images. The screen in in a red hue with green blur.

If you have any suggestions on what caused this and what we can do to have this fixed, I would greatly appreciate your advice.

No blue auto convergence when performed by menu buttons


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.

Image burning on my screen


This is called BURN IN. BURN IN usually occurs when any one picture remains on the screen for an excessive amount of time. To my knowledge, there is no way to remove these annoying "brandings," however, they can easily be avoided by changing the channel on the TV, or not leaving the TV powered on continuously (especially on just one channel).
