I see rainbow on my color screen tv rca model r52wh74 color issues.


The problem of your tv is the convergence try to adjust it manually in the setting of your tv. If still same or no effect the convergence IC is already defective. You can find it inside your tv it is connected to a large aluminum called the heat sink it has a marking of stk- followed with a number.Try to replace it.

Hitachi projection TV - video is in 3d rainbow


This sounds like a convergence circuit problem. Your set has two convergence IC chips (integrated circuit). One is for the red CRT, the other is for the blue CRT. This is a common issue with projection TVs. It is not a difficult repair if you have any experience with electronics and soldering. Both convergence ICs should be replaced at the same time. The part is IC (STK394-160E) and is available for around $36 or less. If you have a shop fix this they will likely charge $300-$400. If this information was helpful or if you would like to know how to do this repair in more detail post back on this thread. I would be happy to walk you through it.

Your TV most likely has a convergence 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 are some photos of convergence problems.

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 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. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Convergence


Okay, usually the parts that go bad to make the convergence option drop from the menu are the following. Fusible Link (FL1231) Diode (DP1231) and capacitor ( C1230) the numbers in parenthesis are the actual component locations on the board. These items fail causing the set to think its a direct view set instead of a projection unit.
