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.

Multi- color bands - twisting wave pattern cross the middle of screen and can not get image to lock -flickers both horizonal andf vertical. Would this be the same 2 IC chips- last time i had this problem...


Ur tv have convergence problems,it dead.U must have soldering tools,solders and know how to solders to fix convergence problems.U must replaced 2 STk convergence ICS,and some or all it resistors.Tries websites Tvrepairworld.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost U $300-$350 for parts and labors.

Replaced IC chips, but can't fine-tune convergence.


U know how to use a multimeter right?Check and replaced all the resistors near the 2 convergence ICS.Most resistors are big and blue core in colors.

The colors are distorted and there is triple images


Hi,
triple images show failure of convergence out ICs in TV, these are two big black ICs mounted with aluminum heat sink on D board, replace these ICs with same number STK392-560 and problem in your Sony KP-46WT510 will be solved.
Required ICs are available in Part Store.
Let me know any further question, if any.
Thanks.

It sounds like a convergence problem; either bad solder connections at one of the convergence Ic chips or a bad Ic. if this was helpful give me a vote----if one of the chips is now bad it will have to be replaced(usual thing is to replace all the convergence ic chips---most use two and a few 3.

My t v pictures are sharing colors


if its a pt47wx53 it sounds like the 2 convergence Ic chips are gone--also--there are several blue 2.2 ohm resistors around them---if any are discolored you will need to replace them also---this set uses two STK-392-110 convergence IC chips---you will have to remove the light box---I can tell you how--look for the convergence ic's inside and take a close look at the 10 or 12 powder blue resistors around them---if any two are white in the middle(discolored) they are gone--if you need any help let me know.

Convergence Issues


Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip 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 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.

2c07611.pngSolution #1

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 kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

HC-P4752W - IC Replacement vs Convergence Module.


The colors weren't lining up correctly on my HC-P4752W which is only about 30 months old. I did a little bit of research and got ahold of the people at http://servicemanuals.vstore.ca/ They recommended replacing the IC's as well as the IC resistors. I purchased the replacement parts from their site and made the repairs myself. I should mention that I didn't have any previous soldering experience. The repair was easy and a complete success. You may find replacement parts elsewhere for slightly cheaper but what you won't find is the prompt and detailed customer service that they provide. They gave me there # and said to call if I had any questions before or during repair. I took advantage of their services and got answers every time I called.
