Devices: Any Projection TV with a Convergence Amp board

If I knew which Mitsubishi Projection TV you're looking at, I could help quite a bit more. In general, the "convergence chips" on a typical Convergence Amplifier board are actually two STK's mounted to large heat sinks. "STK" is electrical engineering slang for "Convergence Amplifier Integrated Circuit".

Here's a helpful Solution archived at FixYa:

You'll see in the photo that the STK on the PC board actually have part numbers on them that begin with "STK".

I have a Hitachi 43fdx01b and I have just replaced the two convergence chips because of a "Red" convergence issue. I learned the hard way about the desoldering and resoldering, but got it done. Now i...


did you check the resistors by the convergence chips? check to see if they are open. the resistors are usually lined up on the other side of the heatsink as the convergence chips.

RK42 2.2 ohm 1 Watt
RK46 1.5 ohm 1 Watt
RK50 2.2 ohm 1 Watt
RK54 1.5 ohm 1 Watt
RK58 3.3 ohm 1 Watt
RK62 1.8 ohm 1 Watt

the convergence chips to be used are
IK04 STK394-160E Part #: CZ01341
IK05 STK394-160E Part #: CZ01341

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.

  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

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.

Blue convergence is off right will not adjust


Hi. there is a malfunction that has occurred within the convergence chip that is located on the PC board(demod). this is a Hybrid chip that controls the calibrations of the RGB streams. If this chip becomes unstable, it will not allow proper calibrations.

Replacing this failed chip will fix this issue.

The actual sony chip is not available at this time but, there is a compatible chip that will work with your set. i will post a link to the affected part below.

Service code needed to complete convergence adjustments


I have the service convergence code: mute-1-8-3 (make sure your tv is on and set to antenna. if it doesn't work press S. Mode and make sure is says standard then re-enter code.

So, I have the code but I need the convergence chips. Where did you get the convergence chips?

Red Convergence Bowing




You have a convergence problem. Here are some of the most common symptoms.
 
Screen looks 3D
One or more colors can't be adjusted when using the convergence menu. 
Screen is bowed in but stationary.

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.

SPEED BUMP OR BOWING


Your convergence chips and convergence resistors are going bad. When they fail the screen colors will look distorted/3d looking. Another symptom is one or more colors can't be converged using the convergence menu. You can purchase the parts over the internet. Just make sure you get Sanyo brand convergence chips and the correct flame proof resistors. You can also check the site www.TvRepairKits.com for a kits.  Just make sure you replace both of the convergence chips and all of the convergence resistors.

Convergance chip


Thats the regulator chip for the convergence circuits thats the one youre most likely needing, as your chassis doesnt have convergence ICs. You can get that IC at the following link and they will provide free installation instructions and free on line tech support just in case you need assistance. Here is the link.
