Tv screen colors are separating. cannot align

What you might be experiencing based on your symptom sounds like a damaged convergence IC.

If you cannot move the colors with the convergence menu then you have a damaged convergence IC.

With any Projection Television that has a damaged convergence IC, you do not want to continue the use of the set. If the IC’s continue to fail they will cause a short in the power supply and cause your television to not power up, and possibly damage the CRT’s in the set.

With that aside I have some support suggestions that I have put together that may help you make an informed decision.

You should be able to get a local service center to repair this at your house for between $350.00 - $450.00.
If you want to repair this set yourself, I have some instructions below that will be a help to you.
While it is not a very hard repair, this repair can be a bit tricky. If you have a 45W soldering iron, solder, solder wick, and heat sink compound you can repair it yourself.

When you remove the old IC's, please be sure to remove all of the old heat sink compound, as it can act as an insulation for the new IC's and cause them to overheat. I usually clean the heat sinks with alcohol and a small rag.

There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets only have one. If you only have one, it is right in the middle of the set on the center circuit board. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110.

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.

If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.

I hope this information allows you to resolve this issue.

I have attached some photos of really bad convergence problems, your picture may not be exactly as bad as these, but here is something to compare your set with.

If red or blue will not adjust in some direction--you have a Convergence circuit problem---

This model (WS-55809) uses two of the STK-392-570 Convergence IC's---

Green for a good reason is not adjustable in the customer mode---it is only adjusted for the Geometry or straightness of the picture and then red and blue are adjusted to it.

If you are able to do this repair yourself you can save the set and a lot of money---most shops charge 300-400 for this type of repair in this set.

You can buy both chips for about 14 dollars on Ebay- and I have step by step---start to finish instructions for this repair in this set--they tell also everything you will need to do and what you need.

If you want the instructions let me know---I am not allowed to post MY email here.....but you.....

Not everyone can do this repair---Let me know if you have any questions or need advice----

If you get someone else to do the repair make sure BOTH chips get replaced or the set will have the same problem again in a few months.
