Question about Sony KP-65WS500 65" Rear Projection Television

1 Answer

Need to find a place that carries authentic Ic's (STK392-560)

I have been reading up on how to replace them and I think I have a pretty good Idea of how to do it. I have taken one of them out allready. My problem is that I can not find a good place in which to purchase these parts from. The Ic's also have a number on the top right corner, in my case the number is A3G01. Now I seem to locate different places that carry the product but all of them have a different number in the right hand corner, why? I also read to look out for imitations and that if the code in the upper right starts with B then they are imitation parts and not to purchase them as they will fault again. How true is that? The pricing is really confusing me as well as I have seen some from $5.99 all the way up to $35 and they all state that they are authentic Sanyo parts. Any help on were to locate the authentic part will be greatly appreciated. Thanks for you help in advance.

I just replaced mine. I got them from ebay. Get the sanyo originals. The numbers in the upper corner don't matter. Just the STK part. DON'T get cheap ones. Get actual Sanyo originals. Should cost around $15 or so may $18 after shipping. Don't forget to check the Pico fuses too. They are the yellow resistor looking pieces under the IC Heat sinks. They are 3.15 on the IC's and 5a on the power board. I can send pics if you need them. Good luck.

    I've never heard of the 'B' imitation. The ones I ordered didn't have B's on them and they are working flawlessly. So maybe that's something to look out for....?

Picture looks like it is doubled, and has a blue and green tint to it. When green bulb is covered up picture realigns and looks pretty good, does it need a bulb replaced?


If you try to adjust convergence with the flash focus, perfect focus, (depending on the make of your set) or by manual convergence and the lines will not line up or even move. What you might be experiencing based on this symptom sounds like a convergence IC problem.
I have repaired hundreds of these sets, so if you have any questions after reading the following, please reply to this post and I will help you in any way that I can.
With any Projection Television that has a damaged or interment convergence problem, 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


How do I tell if the IC’s are damaged?
When looking at the area around the convergence IC’s you see some resistors that have changed colors, or you test a resistor and it no longer reads the marked value. You will have to replace the IC’s and the supporting components.

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.


Where are the IC’s located and how do I find them?
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

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

I have a Panasonic PT53Wx52C and although i line up the convergence, the picture, especially when not close-ups, are very fuzzy. Any idea what I can do to remedy? Please


If you try to adjust convergence with the flash focus, perfect focus, (depending on the make of your set) or by manual convergence and the lines will not line up or even move. What you might be experiencing based on this symptom sounds like a convergence IC problem. But if the set fixes itself you will need to have it repaired as soon as possible if you wait too long there are several components that will fail in due time. If you want to repair it yourself or know someone that can solder components on the circuit board, you will need to re-solder the convergence IC’s. All you will need is some solder wick, a good 45W soldering iron, Acid free solder and some solder wick (this is for the clean-up of solder joints and cleaning up solder bridges.

I have red shadows on my tv. Just started all off a sudden. I have read in other places of a convergence issue. Is that easy to fix


Your symptom sounds like a damaged convergence IC.


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.

They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110, and they are located on the signal board (on the left as you look into the back of the set).

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.
There are also two resistors on the front of the board located in the middle that are fusible link resistors, these should be checked for opens and replaced if they are found so.

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.

Your symptom sounds like a damaged convergence IC, whick you have found to be true.

There are two and large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink.

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.

You will also want to replace the white heat sink2.gif compound that is on the heat sink2.gif, just scrape it off, then clean the surface with alcohol. Then apply a thin coating of fresh heat sink compound, if you do not do this important step the new IC's will not last long as the old compound will act as an insulator to the heat transfer.

I would suggest that you contact a service center in your area for a complete diagnosis and repair, as this type of repair can get a little tricky. But if you want to repair the set yourself, just remember to be careful. The capacitors and CRT’s can hold a charge and may shock you.

Definite convergence prob - with Red. on a mitsu


Your symptom sounds like at least one damaged convergence IC.

On Mitsubishi's you can sometimes rework the solder connections on each of these IC’s, although, if the convergence does not fix itself from time to time, you most likely do not have a bad solder connection. You will have a faulty IC. I recommend replacing them both at the same time because the chips legs can fall off due to the heat of the IC. If you have a good low wattage soldering iron ~ 45W (available at radio shack) you can perform the repair yourself, and this will most likely take care of the entire issue.


I like to remove the board that the IC’s are on so that I can unsolder the connections and clean then up using solder wick (this is also available from radio shack). Removing the board is not a real issue as the connectors are all labeled with an alpha number, so that you can connect them back real easy. There are three in the middle towards the front that I like to mark with a sharpie as they are the red green and blue convergence coil connections (they are all the same size in a row). Just mark them with slashes, like I, II, III, or something like that. If you mix them up it is not a big issue, you can test swapping them around until the picture lines up.

Please be sure to remove the entire white heat sink compound on the heat sink and apply an even coating over the back of the new IC’s. You should also bolt them down before you solder them in so that you have them at the correct height.

There are two very large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink. I think that the IC numbers will be IC8001, 80002.


The IC’s are large and black, you cannot miss them. They will usually have an STKXXX-XXX number on them.

This repair from a good technician will normally run from $250.00 - $300.00, and sometimes more depending on your area.

There are several schools of thought on the replacement of parts and I firmly believe that you get what you pay for, so don’t buy the cheapest IC’s that you can find. One company I worked for tried this and it only caused more work for the technicians, as we had to replace them with the more expensive ones in the end. I would think that you should be able to find these for around $60.00 each. If you can find the exact
Hitachi part, or Sanyo, even though the numbers on the front are the same, and they look exactly like the $10.00 ones, they are better and more reliable.

I usually order my parts from Andrews Electronics in
California, they will have the OEM components that you will need.

IC Convergence replacement


you will no doubt need two STK392-560 ICs and quite possibly two 3.5 amp pico fuses, and its a good idea to get two 4.7 ohm 1/2 watt resistors as well. You can get all the parts you need at the following link and they will provide free installation instructions with pictures and free online tech support while you do the actual repair if you need it. Heres the link.

best IC for your repair.....Please read some of my solutions for
more details.....Here is the basic idea...when I repair a convergence circuit,my first thought is = are my replacement parts OEM quality or better ? A cheap generic second will just BURN RESISTORS so why would I use them? New,proper IC's
should never burn resistors ! The wattage of resistors is a minor
