Question about Panasonic PT-53WX42 53" Rear Projection Television

Taking out board A on the Panasonic pt47wx49?

STK convergence modules (the black things attached to the heat sinks) I picked up where on Ebay, I got the same exact number that was on the origianly part # so I have those already...
I am stupid and dont know how to get the A board out??
On the right side of board A the are four sets of tracers (white clips) that connect the to the power board...How do those clips deattach?
Can some please help me take board A out so I can solder in the new ones?
I was already to switch them out, had everything label and ready to go, but I can't loosen the white clips on the right hand side of the board and I don't want to force them?

Don't separate them, Just take out the four screws that hold the frame for the A and D modules and flip up the whole thing to get to the bottom of the A board where you can unsolder the 7001 and 7002 IC's. It's less work and less chance of breaking parts. Also, make sure you have genuine Sanyo parts. Generic parts don't last. There is a substitute for the part that is supposed to handle the heat better but it costs two or more times the price of the original parts. I just finished this job and it takes about two hours start to finish including checking all 12 of the blue resistors which can cause an IC failure.

What is the standard price of the convergence amplifiers and how many are needed for a 48 inch HDTV?


If it is Panasonic PT47wx49 it uses two STK-392-110 CONVERGENCE chips--On Ebay select search, then advanced search and then search by seller---look for seller: sewsales55 You can buy both chips for about 12 dollars plus shipping(price for a pair with 6 month warranty)

If you need instructions on this repair let me know--pretty easy set to do this on--

You need to re-solder the circuit board that contains the STK convergence modules. They're on the center circuit board attached to an aluminum heat sink that's about 8" long and 6" tall, about dead center in the circuit board. You may be able to recreate the problem (hour glass effect) by gently moving the heat sink (which the modules are connected to). This gives the hour glass effect on the picture and the advanced convergence screen. This is an indication that the modules pins aren't solidly connected (meaning soldered) properly. Remove the circuit board and clean the old solder off & resolder the modules pins to the circuit board reconnected the board and then retest by again pushing on the heat sink. This is a caused by a minimum effort (a.k.a. minimum cost) solder job, probably done in some 3rd world sweat shop. The "factory" job was good enough for 3-4 years but the heat (and these modules do create a lot of heat) and stress created from repeated use eventually takes it's toll, weakens the pin connections and our problem occurs. take the appropriate cautions working around the high voltage of the set & use a non-conduting piece of wood to push the heat sink when we doing tests. Best of luck, hope ya fix it.

If soldering doesn't help, then the modules have died and need replacing. Don't buy the $10 cheap ones. Most of them have an upgraded version that is stronger. Also look for any burned resistors in the vicinity of the modules.
Best of luck, hope ya fix it.
