We have been told we need to replace the convergence amp on the Mitsu WS-55819 projection TV. Can we do it ourselves?

    This answer was more than I had hoped for. Now I am excited to get the parts and do attempt the repair. Hopefully we won't fry ourselves in front of our children.

    Hi again, Last question, shouldn't we be ordering resistors upfront at the same time we are ordering the ICs? We might as well replace them too if there are not too many. Thank you so much again in advance.

Yes you can provided you can handle electronic devices(safely) and can solder. Let me tell you all that you have to do so that you can decide for yourself. First up you should get 2 convergence ICs(STK392-570),
test the resistors in the circuit with a multimeter set in ohmmeter mode. If they are blown replace them with ones of same values. Once thats done apply thermal grease on the ICs remove the old ones(un-solder and de-attach them from the heatsink) and solder the new ones in. You may also have to perform a convergence mode adjustment. Let me know once you have replaced them and I will tell you how to do this.

    Thank you so kindly for your answer! I think between two intelligent beings (my husband & I) we can attempt it. We have fixed many appliances and done several repairs together but never tackled a TV. I think we might try it based on your answer. It'll be fun. lol

    Also, the advanced features menu in the Owner's Guide does have the instructions on advanced convergence but I think you might have another trick up your sleeve to do that so we can attempt to have you explain it after we replace the ICs. Thanks again!!!!

    There is a trick to ensure that you don't fry yourselves :D LOL! Take a bulb holder and attach two wires to it. Plug a bulb(60W recommended) into the holder. Unplug the tv from the power supply. Now if you have a multimeter that has its own power supply then touch the two wires on the leads of the capacitors. The bulb will glow momentarily and turn off which means the capacitor is discharged. Repeat until you have discharged from all of the caps so that there will be no residual voltages on the board and you can safely work on it. Also wear an ESD(electro static discharge) wrist strap for a moment and remove it to help drain the static in your body. Otherwise it may fry the ICs.

    Yes its better you order it along with the ICs. Make sure you get the values right. Since you have fixed so many stuff you may be knowing how to read them. If not then you can use the guide at the link below

    Note that you can also get the resistors at a radioshack store or any other electrical store just in case you can't find them online.

Can not align red even though convergence board WS-55819

Did you replace the center board with the STK-392-570 chips or the Digital convergence board mounted on it?


98% of the time if you have a convergence problem it is on the center board---the small board on the left under the metal shield box stores and controls the convergence of this set.


WHICH DID YOU REPLACE?

I am here to help----I have fixed hundreds of Mitsubishi sets with convergence troubles.

Mitsubishi WS-55819 TV Wont turn on.

code stands for loss of vertical. I had one of these if you can check pico fuses, check the ones on the main power board the one with the 2 convergence amps if any of them are blown then most likely the convergence amps have shorted out.

Mitsubish WS-819 Protective Shutdown. 2 blinks, pause, 2 blinks

Over 95% of the time a 2 - 2 blink code on that model is a convergence output problem. You need to replace both of the convergence output IC's and perhaps the pico fuses feeding them voltage. The pico fuses are F9A04 and F9A05. They are on the same board with the convergence outputs.

Mitsubishi WS-55819 Won't turn on

If F9A04 and F9A05 are open the convergence ICs will need to be replaced as well as the two pico fuses. You will need two STK392-570 Convergence ICs and two 5 amp pico fuses. You ca get the replacement parts at the following link with free installation instructions. heres thelink.

WS-55819 Mitsubishi Rear projection TV Picture goes blurry

Convergence ICs are bad need to be replaced. You will need to replace both of them also check the resistors right next to the IC often 1 or 2 of them burn out when the IC goes.

Mitsubbishi hd tv 55815 series

I believe that what you are seeing is the convergence IC problem that these Mitsu sets have. If you whack the set does the picture snap back in correctly? If yes, then the convergence ICs need to be resoldered.
