Panasonic PT-56WX33G HD Rear Projection TV

I also have a convergence issue, but I have looked inside for the Convergence Ic's and can't seem to identify them, in my case, it's the red that is off. I saw a module labeled as a13266 and I thought that was the module, but can't confirm. I was wondering if i am looking at the right part, or if If these IC's would under something or where they are?

SOURCE: JVC AV48WP30 convergence ic

I'm in the process of trying to replace both convergence IC's in my JVC also. I was able to buy both IC's (they look like black semi-rectangular components with 20 pins sticking out...like a computer chip only much bigger) at a TV repair shop for about $15 each. They were clearly labed STK392-110 (but could be 150 or 180 if you wanted to upgrade).

What is convergence IC problem


Convergence has to do with how different colors are displayed on a screen or monitor - typically the rear projection and some other types. When colors are overlapping to create unexpected combinations, or leave gaps between areas where overlapping is expected that results in a shifted red, green or blue image strip or edge - that is an indication of a convergence issue. They can look like this in severe cases:

c31c1afa-63aa-42ee-9cc7-7b07e09559be.jpg


Colors will drift, so manufacturers often include a utility to help you nudge the colors back in the right place. Most times this utility is buried in the Set Up Menu and when activated, produces a screen like this:

6c0170ed-2cd6-4dfa-bbcb-a10a7d20f92f.jpg


You will need to adjust the red, green and blue colors for each cross so that only a white cross is displayed. Keep red, green and blue fringing to a minimum. When you're done, the screen should look black and white, symmetrical and straight - like this:

40e4c7a6-f241-4888-a151-d21b0792cb71.gif

Problems arise when you are no longer able to coax the utility to give you these crisp, B&W results with no red, blue or green ghosting. This is often due to a failing convergence integrated circuit ("Convergence IC"). Many times, replacing it will solve the problem, but other times it can be the result of failing components either ahead or after this IC. If you're attempting to replace this IC, please make sure the TV or monitor has been *unplugged* for 24 hours or more to allow the dangerously high voltages to dissipate.

Red color convergence issue; Red lines are curved


This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Thought I had a convergence problem - red is still broke


KCOZI,

I dont think you have problem with Red Gun.
One of your Convergence IC is faulty with 2 RK series Resisitor(Low Value) in Convergence
Amp Borad.If you changed IC look for RK series Resistor (may be 3.9ohm/2.7ohm)


Dont forget to Rate!

Good Luck
