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

1 Answer

Board Clips I am trying to unclip the 4 white connectors that connect the main board to the convergence board. I know that these unclip from the right side and fold up to the left. My problem is that I cannot figure out how these clip together, and or where to squeese to release.

I am not an expert, but we just used small long nosed pliers, grasped the entire right side of the horizontal portion of the clip, and rotated it up and toward the L side of the clip. It pops out pretty easily.

In replacing the two STK-192-150 chips, I need to remove the board. I am concerned about the 4 white interboard connectors along the left side of the board. Can you just pull up the board?

In my experience it's easier to just pull the chassis out and flip it over. The white connecters can be disconnected by applying sufficient force pulling up, you can also use a screw driver or pen. Place the pen under the connector flat and pull up on either side to apply even force to the entire connector. Goodluck and remember to mark the convergence connectors 1, 2, 3 so they go back where they belong. They are the little white connectors that are identical.

Tunesmind, were you able to pull out that board, if so, did you pull or push on the nubs on the connector

How do you pull the board out with the convergence chip on at as it is still attached by a hose type connection. if anyone can talk me through steps that would be a god send. James

If you are asking about that TV that has convergence board on lower front and it has hose type connection wires then remove screws of aluminum heat sink sheet that holds D board and convergence chips and take it off from TV front, hose type connection wires has enough length, approx 2 feet, to bring that board in front of you for soldering work.

If your TV is Sony KP-51HW40 as question shows its model then it has D board at rear, convergence chips are mounted with aluminum heat sink on D board, unplug connectors on D board but do not unlock plastic lock rings that hold hose type connection wires as that will help you to replug connectors in right connectors.
remove screws on D board that holds it with plastic chassis underneath, unlock few locks on its sides and take it out.
Hope that info will help you.

Picture is squished in on all 4 side of TV and colors are all dis

You will not find the problem in deflection board it will go back to convergence board,I repaired one that would not Magic focus cause was on connectors from power board to convergence board the one closes to up front of board one of the pinns was bent under so when i pluged it back in did not know after lifting up connector under tiny pins 1 of them was bend under straighten it so it could plug in right Fixed problem.

I just did this repair last week and here's what I did... I took a flat bladed screwdriver and CAREFULLY twisted it underneath each end of the connectors EQUALLY to be sure they raised out without damage.

Pt-53wx52 reaer projection convergence

No usually on the panisonic its the Ics they hardly ever blow resistors as well , but its possible. the wire bridges stay connected to the board on the left one with the Ics and they seperate on the right side. just slide something under the right side of the bridge so to speak and lift up they will come un hooked and stay attached on the left board. you can check the resistors by lifting one side out of circuit by unsoldering then check the resistors for resistance. they have to be lifted out of circuit on the one end though or the readings wont spot a open resistor.

Convergence IC question...

Those are the wire connectors between the A board and the power board. They just lift out on the power side. Take a small screw driver and just slide it under the bridge close to the end nearest the power board and gently pry they will pop off and stay attached to the A Board (conversion) There should be 4 of them

Taking out board A on the Panasonic pt47wx49?

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.

Panasonic pt47wx49 taking out board A to replace IC on heat sink

You have a problem with 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. 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 (not sure what you mean by white clips, but you should be able to take out just the convergence 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. 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-conducting piece of plastic to push the heat sink when doing tests.
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.
