Shanan, I'm afraid that a problem like this might be a tricky one to find. The problem is that it does not happen all the time. You might be able to find a voltage drop or change when tapping on the sweep or power circuit, or by heating up or cooling down certain sections of these different circuits. But for a handy person or a novice at electronics, probably not possible to track down. Good Luck

Hi Larry,

I have a Mitsu WT 42313 and appears to have a covergence circuit issue similar to what others here discribe. Mine specifically distort the picture for about 2 - 3 inches on the left of screen throwing a "ghost" picture in the three colors and sometimes the picture goes into a bow. I heard you might have the manual / procedure for replacing the covergence circuit stk394-250? My email is bwilsenach@gmail.com

I see the STK's are sony is this correct?

Where would be a good source to buy it from. I see them anything from $7 - $30.

Thank you,

Bernie

Yes Bernie, if does sound like there is a convergence problem with your TV set. If your set has the STK394-250, and there are two of them in this TV set but I do not have any how to do instructions for this procedure but if you can solder on solid state printed circuit boards, the job really is not that difficult and you can save several hundred bucks by doing it your self. If you do not know how to solder on printed circuit boards or have no experience whatsoever, play it safe and find someone who does or have a pro do the job for you. If you overheat the solder pads on the IC's you could ruin the printed circuit boards. No on another note, the IC's are not made by Sony, they are made by Sanyo and you really have to be careful where you buy the IC's from. A lot of the IC's you see out there that are less expensive, like the 7 to 15 dollar range are most likely cheapo after market types or the factory rejects. ONLY USE TRUE SANYO REPLACEMENTS!! I buy my IC's from HERE. Also, before you install the new IC's onto the large metal heat sink, apply a good layer of heat sink compound onto the backs of the new convergence IC's. Good Luck with your repair.

Thanks a Mil Larry, I have repaired other circuit boards before so think I can wing it. To pay someone $500 to do it is worth failing and buying a new TV for $700! Thank you for the link to your source for IC's. It is great to see someone sharing knowledge like this. I will report back on my outcome.

hey larry i meant my Mitsubishi VS-60805 tv monitor/screen/piuture display slowly started bending and getting distorted until after a while it turned pitch black. i unpluged the power cord and turned the tv on again and the monitor/screen picture was back and just fine. but 10min later the same thing happened. i can still hear the audio/sound of the tv/chanell though. i found the STR... convergence boards... but before i order the new ones and dig into it i just wanted to get an proffesional confirmation that the problem of mine is the convergence boards indeed? i noticed just like you said on the forum replacing those IC is a very tidious/time consuming soldering task. is there anything you can recommend/confirm me to do?

PS.: I'am also gonna try to find the Convergence power supply fuses that can go bad in the main power supply marked F9A04 and F9A05. anybody knows where tose are or anybody got manuals?

thanks a lot,

If you look on the chassis from the back of the TV set, You will see a larger board on the left side of the main TV chassis, and a smaller one on the right side. Now looking at the smaller board, only the smaller board on the right side of the chassis, that is the power/deflection board. On the right side of this board only, near the middle front of the board, you should see those on board fuses. They do not look like a typical round metal fuses. They could be black, green, or yellow in color. You should see the marking on the board where they are. I have added a link on soldering, in case you are not famiular with it. GOOD LUCK!

Larry, I replaced the 2 convergence IC's 5 months ago and it's been like new! The day before Superbowl my Mits ws55809 won't power on. It shows 2-2 on service codes. Also when plugged in AC there is no 3 LED flashes. My service manual says is no 3 LED flashes the microprocessor not functioning. I've read many posts that say possibly needs TDA8177(IC4B01) Vertical deflection booster. I ordered that and more PICO 5a fuses incase F9A04 & F9A05 are open. Do you thing I'm going in the right direction?

IF FA905 or FA904 is open, you have a convergence problem. Where did you get the the replacement convergence IC's from?

Got them from Bluestar International Components- Blusestar-online.com--it's been wroking fine since it installed them. The difference I've noticed this time is now when AC is plugged in I don't get the 3 LED flashes showing the microprocessor is working properly.

If Sanyo is not written on them, they are aftermarket type IC's or factory rejects. And that's why they did not last long. Also you need to scrape off the old heat paste compound and install new before installing the IC's.

Hey larry, this is stephen again. I dont know if you remember but I had talked to you about me thinking that my ics went out. I replaced them and I had the same problem. You had told me that you thought that it could be pico fuses or fuses that may have went out. I did not have the manual at the time but I have downloaded the manual now. If it would be helpful I will email you the manual. It is good for many different manuals. That way maybe if someone needs help in the future you will have access to the manual. Another thing if you want me to send it to you, would you varify and see which fuses you think it would be. Thank you

Check R520 and R522 off of T510 transformer. They should measure .82 ohm. They use these resistors instead of circuit protectors or fuses in these older TV sets.

You should be able to get .82 Ohm Resistor at 2 watts from Radio Shack or someplace like that. You could even use 1 ohm, as I have in the past. Just make sure they are fusable resistor and flame proof.

Thlanks alot. You have been very helpful through this whole experience. I appreciate it greatly. One more question if you dont mind. I am sorry. If the fuses do not fix the problem where would you go next, as I have already replaced the ics and I am pretty sure that it is not the soldering?

We will cross that bridge when we get to it. No need to spend precious time figuring what it could be when in fact I know one or more of those resistors are bad. You need to look at the schematic of the convergence and measure for the plus and minus 24 volts at the IC's.

Well on my Mitsubishi I did have a convergence issue, however after looking at the bottom where the IC's solder onto the circuitboard, I noticed that there where about 4 "pins" loose. After soldering them back on it worked like a charm!!! The cracks where so small that you could only notice it if you pushed on each with a ballpoint pen. I can thank my 2 year old for banging against the TV for this.... geeesh :)

Thank you for the support I have received here.
