Converange chip-Where can I order one

I know what is wrong with my tv and I see someone just had the same problem yesterday with theirs. I do beleive the expert was texmen or something like that. Quite odd my tv is having the same problem as their on the same day, the converge chip needs to be replaced. I have contacted panasonic on this for my tv was made in august 2001 and I just talked to a tech today in which he was the one he gave me and he stated that the orginail chip in these only last 6 years. well my tv isn't even 6 years old yet. He also told me he has a life time chip! Why isn't Panasonic putting life time chips in these tv's to start with. The manager had nothing to say then. My tv isn't under warrantly being it is over a year old, but panasonic refuses to tell me the product name or number of how to get the chip to have it replaced myself. How do I find out the product name for the chip and the number of it so I can order it. It is the converge chip to make the colors line up.

Re: Converange chip-Where can I order one

This is very strange coincedence it seems the more I search this problem the more people I am finding with the same issue. This morning Aug 3 2007 I turned on our Panasonic PT-47WX42C to find this convergence problem! (distorted colours-off alignments) I, like yourself Hultsie would love to get the schematic diagram for our unit and change out the IC(s) myself. If we work together I believe we can accomplish this task! Please contact me at if you would like to give this a go! I certainly will try to exhaust all avenues before I part with hundreds of dollars for something I know I can service myself. Oh, the defective IC(s) will more than likely have the values you need written on top of the chip...once you know the ones that need changing your local tv repair or even panasonic (if there close by) will sell them to you.

John, my thoughts is something in the main power supply. I don't know what an opto chip is but I've heard of Optocupler IC's.
May be a good idea to give a call to some local TV Repair Shops especially ones that work on Philip's and see if you can speak with a tech to see what their thoughts are on what the problem is and what a repair cost may be.
The issue is one of hauling it to the TV shop or having them come out to you.

Pioneer sd-p5073-k am in the process of replaceing the converinage chips. and cant seem to find any pico fuses anywhere on the converange board or main board there are several regular fuses on the main...

Make sure to check all the fuses with an ohm meter. Pioneer also have terrible solder joints. I used to "sweep solder" the whole convergence board. Down on the power supply you should find the pico fuses. They are pretty small in compairison to the glass fuses.

My color is all out of whack on my SP-55W3HF Samsung. When I run the convergence alignment, I find that my red will not align. The red display markers are also bowed. Any ideas?

Your TV may have 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 Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

HI, this is a failed convergence chip that is located on the convergence board. it will need to be replace ASAP. you can just replace the chip or , you can order a new board.

Replacing the chip can be a rough job if you don't have tech experience. if you are a fluid tech and you can solder and know your way around a circuit board, just replacing the chip will cost less. if you are not an experienced TV tech, i recommend a service call to the nearest TV tech to replace the convergence board.
