My Panasonic PT-53WX42F blue adjustment does not respond. I do not know if I need the IC or amplifier. There are two IC's listed for my unit, do I need both or is there just one applicable? Can they be installed easily or is delicate soldering and heat sinking required?
There are a pair of STK series output ICs that fail. One is for the blue and the other for the red. You will need solder wick to de-solder them. When your done you will need a alignment DVD and know how to do the service adjustments. If you've never done any electrical soldering before, it might be a good idea to have pro do it.
I have PT-53WX52F and have a similar blue convergence problem. I have the service manual and followed the service adjustments to no avail - I cannot get the blue to fill the screen. I am thinking that I need the signal processing board (TNP2AH035S) replaced but it costs about $500! So, I am hoping that I can get the problem fixed by replacing the STK series output ICs you mentioned. Are they on the blue driver board?
Nope, not on the driver board and their shouldn't be on the signal board. They are usually on their own board. I'm not familiar with your set, so I can't tell you exactly where they are. Look for a matched set (3) of heat sinks. The outputs will have a clamp bar across them, so you can't see the part #s. If your still at a loss, PM me some pictures of the chassis.
