How do i set the color for picture


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.

Blury,dark and off color picture


Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • 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.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

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

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


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.

Color is off with double image?


Is the image bow-tie shaped, with red, green or blue fringing effects? If so, one of your convergence amplifiers has gone bad. (Bow-tie: at least one of the three primary colors in the picture goes out to the corners, but the top, bottom and sides are bowed in at the center.)

If it is simple color fringing, with no color grossly misplaced, something has messed up the convergence. This may be caused by a strong magnet near the set (for example, a poorly shielded audio speaker), moving the set so its orientation in the geomagnetic field is altered or its components mechanically shifted (rough handling).

If a convergence amplifier is bad, replace it before doing anything else. If you just have minor fringing, see your owner's manual for instructions on using the remote control to adjust convergence. If it isn't in the owner's manual, you'll need the service manual. Caution: if you try to adjust convergence with a failed convergence amplifier, not only will it not help, but you will have a lot of extra work trying to get it back to normal after you replace the amplifier. Try a small adjustment along one edge of the picture. If one or more of the selected color dots in the convergence pattern won't move, and you are sure you are following adjustment directions, stop immediately and proceed with hardware repair.

Convergence amplifiers are usually marked STK392-nnn where nnn is a specific variant number. Two are used; I usually change both because quite a few people have changed one and had the other die not long afterwards. Sometimes there is a fuse in the power feed to these modules that is also blown. If you change the fuse without replacing the amplifiers, you'll probably waste a new fuse.

You can determine if you have a true convergence problem or just need an adjustment very easily. Take a look at this youtube video to find out.

Blury picture double picture


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,Akai2_bing.gif,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...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*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

Bowing picture


may have blown your convergence, does it look like all 3 colors are hourglass or is it just one. If all 3 are bad and it is on the sides it may be a pincushon problem, I dont think you have an adjustment problem I think you have a part failure. If this set is older than about 5 years old it may be starting to have issues with the CRT coolant and the blue may be getting blury, the blue and green will need to be changed also. I would definitly call someone on this to make sure that you get all your bases covered as Fluid is conductive and can cause all kinds of issues up to fire hazzard. (of course that is if it is leaking, and that could be what caused your hourglass issue.)
