Question about Panasonic PT-51HX41 51" Rear Projection Television

Projection TV wil not cut on.

PT-51HX41was working with the blue gun out of convergence arc about 3 inch top and bottom. Finally, unit went out and smelled like flyback had fried. Now, unit shuts off after unplugging ( high voltage). I do not see anything fried inside so I am wondering if I have both a convergence amp issue as well as a flyback transformer issue?

You should first replace the convergence IC's, both of them. Also make sure all the resistors on the convergence IC's are good and not burnt. That's probably what you smelled burning. Good Luck

You will need to replace your two convergence I.C.s.They are two large IC mounted on a large aluminum heat sink.Replace both,look for any burned resistors near them,replace those if needed,and readjust your convergence. Good Luck

Panasonic PT-47WXC43G green ONLY is bowed on bottom and top

Hi,
It still convergence chip problem, check big resistors nearby these chips that would be open or devalued and causing problem, specially in green convergence area, your green tube/ gun is just fine and just not getting convergence output signal to show correct image.
I would suggest to download service manual copy of this tv for small fee from any website and fix the issue with schematics help.
Thanks.

Blue Projection Gun

It is not the gun ,but the convergence IC that needs replaced providing that you have went into the tv menu and selected convergence and manually adjusted the blue convergence.

Red Gun screwy!!

You have a typical convergence problem here that happens on just about every tube type projection TV set ever made. There are two STK IC's that will need to be changed. Best thing to do, if you have any soldering experience on printed circuit boards, would be to get the service manual, locate the convergence amp IC's order the correct parts and not any replacement IC's that cost less the 20 bucks, and change the IC's. If you have no solid state repair experience, play it safe and call in a pro to assist you in this repair. Good Luck
