The colors weren't lining up correctly on my HC-P4752W which is only about 30 months old. I did a little bit of research and got ahold of the people at http://servicemanuals.vstore.ca/ They recommended replacing the IC's as well as the IC resistors. I purchased the replacement parts from their site and made the repairs myself. I should mention that I didn't have any previous soldering experience. The repair was easy and a complete success. You may find replacement parts elsewhere for slightly cheaper but what you won't find is the prompt and detailed customer service that they provide. They gave me there # and said to call if I had any questions before or during repair. I took advantage of their services and got answers every time I called.

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
  • 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.

Most of the time I see this problem on this model it is caused from the convergence chips going bad. Also there are a few resistors that open on the circuit board. To repair this you will need soldering/desoldering tools and test equipment. The only other thing that I've seen cause this was leaky gaskets around the picture tube coolant chamber. This usually causes major circuit board damage if left unchecked. The first problem can be repaired for usually 150-325 u.s. dollars but the coolant leakage problem sometimes is unrepairable.Good luck and let me know if I can be of further assistance. Russmann.

According to your model number, you do not have a color wheel in that set. Check your model number again and please re-post. I will answer it as soon as you post it.

one or three possible answers,

1. check to see if "mute" is on ( dont laugh, sometimes its the simple things that get us flustered)
2, its possible the speakers are gone, if it near anything magnetic, remove from near speakers and see if that solves problem, if nothing magnetic is near speakers, they may be dead. if the sound works only when things are connected to tv, its not speakers, but a component/setup issue. refer to owner's manual.
3. check to see if the red/white/yellow cables are firmly plugged in, or any other sound component that is hooked up from your output source (cablebox/dvr/ antenna) are plugged into the input on your tv.

It may have to go to the shop, if that doesnt work, best of luck

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 overs.

To get fixed either call in a local TV repair company or goto sites such as www.TvRepairKits.com to get a repair kit with instructions.

Check the resistors near the ic, and the fuses to the ic's, i bet you will find an open fuse. the fuse will look similar to a resistor without color bands. use a dvm and set it on ohms, with the tv turned off.
