Zenith R49W36 Rear Projection TV Convergence IC problem

Jimbo
I have a Zenith R49W36 TV with auto convergence. I was having some convergence issues and some ghosts on the screen. I read another post where you suggested that replacing the Convergence IC's was probably the answer. I replaced both of the convergence IC's. STK392-570 in my case and when I turned the set back on, It significantly helped the problem but did not fully solve it. I still had slight bowing of the picture and slight convergence problems. I entered into the menu to have the TV run through auto-convergence and as soon as I did that the tv shut off. I cannot get the TV to run through auto-convergence. The TV shuts off about 1 minute after turning it on. Would you have any suggestions? Any help is appreciated!

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. I cant thank them enough for making this possible . 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.
Thanks Guys, I will spread the word.

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.

Zenith R49W36 Convergence issue


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony2_bing.gif,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer2_bing.gif, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms

  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

You can see some more examples and find a fix here

Auto Convergence not working


I'm assuming you were having picture quality problems prior to pressing the auto convergence button. If not then there could be a problem in that circuit. More likely I believe is a problem on the convergence board assembly or in the pincushion circuits. Also, check your owners manual to see if there is a manual convergence adjustment you can do.
