A common problem with these samsung dlp projection tvs is a color wheel , it begins to wear from the motor bushings and the motor starts making a noise and rpm begin to vary, besides the color changing if you notice a hum or buzz be sure that as the motor gets worse the noise will be louder. If you are handy with a screwdriver and can keep good notes you can probably replace it your self. The colorwheel is available from several on line electronics parts stores(partstore.com is one of them) all you need is the model number and the brand, as to the replacement procedure there is a very well detailed procedure on line (with pictures and instructions) just follow the following link: http://www.jangro.com/electronics/samsung-dlp-replace-color-wheel/ ater you teken a look of what the job consists of you can make the decision to take on the job or not. Good Luck!

What is convergence IC problem


Convergence has to do with how different colors are displayed on a screen or monitor - typically the rear projection and some other types. When colors are overlapping to create unexpected combinations, or leave gaps between areas where overlapping is expected that results in a shifted red, green or blue image strip or edge - that is an indication of a convergence issue. They can look like this in severe cases:

c31c1afa-63aa-42ee-9cc7-7b07e09559be.jpg


Colors will drift, so manufacturers often include a utility to help you nudge the colors back in the right place. Most times this utility is buried in the Set Up Menu and when activated, produces a screen like this:

6c0170ed-2cd6-4dfa-bbcb-a10a7d20f92f.jpg


You will need to adjust the red, green and blue colors for each cross so that only a white cross is displayed. Keep red, green and blue fringing to a minimum. When you're done, the screen should look black and white, symmetrical and straight - like this:

40e4c7a6-f241-4888-a151-d21b0792cb71.gif

Problems arise when you are no longer able to coax the utility to give you these crisp, B&W results with no red, blue or green ghosting. This is often due to a failing convergence integrated circuit ("Convergence IC"). Many times, replacing it will solve the problem, but other times it can be the result of failing components either ahead or after this IC. If you're attempting to replace this IC, please make sure the TV or monitor has been *unplugged* for 24 hours or more to allow the dangerously high voltages to dissipate.

Red and green do not overlap, it becomes a double image.


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.

2c07611.pngSolution #1

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.

Picture of a set that needs the fluid changed.

brent hardin,

Your description of the problem sounds like a convergence issue. You more than likely have lost the convergence ICs. They will need to be replaced and the convergence will have to be set. The green beam should not move. It is the standard which the red and green are moved to overlap. Since you have bow at the top and bottom I would replace the convergence ICs. I have a tip at http://www.fixya.com/support/r4220499-change_projection_tv_convergence_ics which explains the problem, how to replace the parts and where to get the replacement parts.

Thanks for using FixYa and for the great rating. Great ratings will keep the experts helping to solve problems. Thank you.

Colors arched and overlapping


if the option for convergence is still listed under the setting section of the on screen menu, then you need a convergence power supply board. If the convergence option is missing from the menu you need the ITC222 convergence missing repair kit. You can get either one at the following link they include instructions for the repair.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro.

Color sudden change


Good day.
Your unit is still worth. It may be a caused of loose contacts along the circuitry. It can be remedied by resoldering the terminals particularly the chroma section and the crt circuit.

Colors red and green overlap


Covergence is off... Check convergence and see which color will not move in the convergence settings... That is the STK that needs to be changed out...
