Sony projection tv convergance trouble. changed convergance chips, checked 8 pica fuses, checked 30 resistors all good


Replacing the IC's and the checks you did usually solves the problem.

Double check your wires - especially the R,G and B convergence wires going to the CRT necks - I've had them mislabbeled from the factory b4 and that really throws you off.
Was there any change in symptoms once the IC's were changed and do you have the negative and + supplies feeding the IC's (usually around 30VDC)
If you have the manual, have you tried service menu convergence adjustments?

Convergence


I'm assume you are referring to a non adjustable convergence option. this will occur when you have a damaged convergence chip set that is located on either the PC board or the convergence board. The location of the affected chip will vary from model to model but, in most units, this can be fixed by replacing the convergence board or chip.

You might consider changing the convergence chips. They do more than just adjust convergence in your set and they're pretty inexpensive.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

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.

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.
