Picture on tv has blue and red going through the top and can people look like they had 2 heads on tv toshiba 42pw23p


try to align it by going into the convergence setting in your on screen menu, some proj tv have a multipoint conv alignment, this might do it for you, if it doe not then therre might be a problem with the red and blue convergence amps and on this model the digital conv module(dcm) can also be at fault.

thats a problem with the Blue CRTs coolant needing replacement. If you look directly into the blue and green CRTs while its playing you should notice a bunch of crud inside the lens indicating that the coolant needs replacement.

Green and pink shadow on my samsung 55in proj tv what can i do to fix it. i all ready fixed red and blue line but green is way off and i dont see any way to fix it


hi, this is the early signs of convergence board chip failure. you will need to replace this board in order to correct the collaboration feature. the convergence is responsible for regulating the RGB stream in you set. if it is malfunctioning, you will not be able to regulate the red blue green streams.

Sony TV rear proj works but color is blue


Problem : 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.

Solution :


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.

I hope this will solve your issue.

Good Luck.

If my solution proves useful please accept it.

If the colors are red,blue,and green, then look for you convergence controls in the menu or off remote. If problem is more intense, then the convergence amps maybe needing soldering or replacing.
