Question about Panasonic PT-47WX49 47" Rear Projection Television

1 Answer

Trying to replace convergence chips on a Panasonic 47WX54J

When I took the chips off the foil peeled off on a couple of the pins (maybe the size of a BB) around the hole. Will this make a disconnection?

It certainly will. This is the connection. I think you may have used a soldering iron that was way too hot for this purpose. You need to get a 20 watt pencil type soldering iron. You will also need to get some small insualted wire to reconnect the new pins to the first solder joint downstream from the pin by following the foil. I hope you are using the proper solder as well. Flux core (not acid core).

What size transistor goes to each convergence chip - location number on board (i.e., 80 goes to r7001, etc.)

Not sure what you are talking about, this set uses two of the STK-392-110 CONVERGENCE IC'S.

There are no transistors that go to individual pins on those chips directly---you are talking about the light blue resistors that do go to individual pins---most are 2.2 ohm and 1/2 size and those are about the only ONES THAT EVER FAIL--HAVING FIXED NEARLY 200 OF THIS EXACT MODEL SET, never seen more than one of the 2.2 ohm resistors bad---

If you want to make sure each is the correct value, Google for the full service manual by model number, no one carries those number to value with location numbers in their pockets, IF ANY OF THE 2.2 were bad set would shut down and constantly blink 3 blinks at the power light.

My tv has a arching green tint towards the bottom of the screen that also gives off a double image. I have a Panasonic hdtv 47 in screen model no: PT-47wx54j

Convergence problems. If they can't be fixed from the setting on the menu then the convergence board's IC's are faulty and must be replaced. This is a job for someone who has some electronics experience.
