I have a convergence problem. The Red colour is several inches up from where it should be, and it is bowed such that it is more severe in the lower center of the screen. I replaced both STK392-110 convergence voltage regulators but... no change. I'd appreciate any suggestions. Someone suggested changing the feeder resistors - anyone got the specs on these?
Hi can you please post if you fix the problem? I have the same set and it just picked up this problem today -- must have come from the same production run as yours!
Some are 2.2 ohms/3.9ohms/4.7ohms if you dont have the service manual and your not sure which b+ resistors are gone and from where they get the drive b+,call a tech and have it repaired
you already have the location and value to replace it your ok,check the other ones anound it and remember thery use duplicates on both ic;s eg: r7013 2.2 ohm r7014 for the opposite side but the 2.2 2watt seems like its a b+ line feed, clip the legs on the opened one and tack it in from the top of the board and see what happens you should be ok if you already replaced the amps.
call panasonic or sears for a replacement remote don't take a sub if offered you can still get the original one ,you will loose form function and features with a sub.

One of the resistors was discolored and open-circuit. This is R7013, a 2.2ohm 2W resistor associated with IC7001 (STK392-110). I'm ordering the part. Anyone got a circuit diagram please? It's a Panasonic PT-53TW53G rear-projection TV. Thanks.
I ordered the resistor from Panasonic. Thanks SRTECH for the tip about clipping the legs of the old resistor since unsoldering it might have needed a little too much heat on the board, so it was easier to do it your way. After clipping away the old discolored i.e. burnt out resistor R7013 I soldered the new 2.2ohm onto the old legs. Tip: when reassembling all the connectors onto the board I noticed that for one of them it is possible to plug it onto the board incorrectly. It is the rearmost chunky black connector (it has 4 wires connected to 4 of the 6 positions on the connector). Turned the TV back on and IT WORKS FINE NOW! One slight problem remains - the remote control is cracked and so I can't complete the fine convergence adjustment. Where can I buy a new remote control for this PT-53TW53G ?
I replaced the STK392-110s also the resistors but the red is still having problem, HELP
