"double vision" caused by bad solder points on convergence chips (check before...


Before you order new convergence chips to try to fix the double vision or 3D look on your tv check the solder points for the chips. If you are able to smack the side of the tv or tap the heat sink for the chips and it corrects the problem than chances are the chips are fine butone or more of the solder points are bad. When I looked at the joints for the chips I noticed hairline cracks around the base of the joint. Re-soldering the joints for the convergence chips solved my problem.

Problem : Convergence Chip Failure ( common problem )

  • 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 kitfor your set send them a quick note and they will put one together foryou. 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.

Regards
Arjun

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem as shown below. Doing so will only make things worse.

60PP9352 60 in. Rear - Blue convergence issue


Replacing only the ICs MAY solve the problem, however, many people have also had blown resistors requiring replacement. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice.
You do not have to replace any transistors to fix this convergence failure.
