Your TV most likely has one or more 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 tmy picture has double image and red shadow top and - 2c07611.pngdirections 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 my picture has double image and red shadow top and - 578ba6c.jpg

I just replaced the color wheel on my samsung hln5065w. Picture is great but there is a shadow on the right side of screen from top to bottom. The shadow on the top of the screen is wider across the screen...

Its a Good Possibilty that its the New Color Wheel causing this,if the colors are not complete on the color wheel then that will be why you are seeing shadow on right hand side of screen.
I know I ordered color wheel for mine and had to send it back,it did the same thing.
I compared it to the old color wheel and the new one did not have Solid colors on it.

Can you see picture behind the shadow? or is it shadow and no picture?

Did you use the Automatica Convergence to try and straighten it out? If that does not help, you can manually adjust the convergence.

Don't recommend replacing the light tunnel if you never had any experience with DLP optical systems. you need to pay careful attention to the way you remove any screws or you will be forced disassembling the engine multiple time to get the alignment correctly.

Double picture

Can you give more details? What do you mean by Double picture? Do you have 2 pictures side by side or One on top of another? Or is it like a shadow behind the main Image? If it is a shadow (Ghosting), check your Antenna - connection, direction, etc.
