If you look on the rear of the set and locate the chassis number can probably assist you. But I will need the chassis number for RCA & Phillips/magnavox.

Your symptom sounds like at least one damaged convergence IC.

On Mitsubishi's2.gif 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.
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.

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.

This set uses two convergence chips--both need to be replaced and the set adjusted----If you know how to do good soldering I can tell you where to look and what usually needs to be replaced---Parts cost should be less than 20 dollars if you buy the parts on Ebay---

Most shops charge 300 or more for this type of repair---I just returned home from a set with this type of problem---in home total repair 250 total---If you cannot do the repair I suggest you shop around and find someone who can do it in your home---any good repair person can do this in about 1 hour---I am getting ready right now to do another one near where I live.

IF YOU HAVE ANY QUESTIONS OR NEED ADVICE FEEL FREE TO ASK ME...I am here to help people.

REGARDS, SD TECH

Service Manual for Toshiba 57H82


By the red being "off" I suspect you have a convergence problem and adjusting will bnot likely fix the problem. The convergence amps need to be replaced but if you email me I can send you the servoce manual... Just provide me with enough info in your mail, model number, because I get nearly 3000 emails a day and I won't likely remember what manual you're looking for...
