Zenith R49w36 problem

I believe the 3d convergence is out on this tv. I have the classic bows on top and bottom of the screen. Where can i get the ICs STK numbers? and is this something that someone should try to fix at home?

Had the same problem with my Zenith TV. Convergence was all out of whack. I purchased a repair Kit from www.TvRepairKits.com The kit had all the parts and simple step by step photos of the repair. At first the repair did not work so I emailed them and within an hour they told me to check two other items. Sure enough they were right! The set is now working perfectly. You guys rock!
I will spread the word.

Double VIsion on Zenith R49W36


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.
