Question about Panasonic PT-47WX42 47" Rear Projection Television
Posted by Ward JOnes on
Confused on where you stand now with this set. And what Chassis is this? AEDP812 or what? Did you change resistors when replacing Convergence amps? Where there any solder bridges?

Did you get the manual from techman, and did his solution work? If not, can you explain what you tried and what condition the set is in now, and I'll see if I can help out any.

Mistacork, I have to agree with tvtek, you most likely have a problem in the convergence circuit. Most likely the correction amp IC's, But if you want to go into the service mode, I can send you a manual very close to yours and this will explain how to go in and adjust, but let me caution you. This is very dangerous to do if you do not know where you are, what you are adjusting, and if you do not write down anything before you change it. The service mode is not a simple place to piddle around in, it can ruin your set if you make a wrong adjustment. Leave your e-mail and I will forward it to you. Good Luck

These are two IC's about 2" by 3". Standing up and mounted to a large metal plate called a heat sink. These are soldered into place on the printed circuit board. They will have on them white letters thats says STK-392-150 or another three letters at the end, I forgot. But If I were you, I would replace these IC's or have them replaced before messing with the service menu, as you could throw out the entire alignment and then when you do get the unit repaired, it will take a lot of time to readjust. The service menu is only for slight touch ups and if parts are changed. Any drastic changes in the alignment is a true indication of a part failure. The service menu is not a cure all or will not fix all the problems, as a lot of people are told by others. A little knowledge can be dangerous in this case. If you do not know how to solder, maybe a friend or neighbor knows how to work on printed circuit boards. Good Luck, and I will send that manual. It will not be your set, but the service menu will be in there.
I sent you what you need to fix or repair your problem. Good Luck
I sent you the proper manual this time,via your e-mail. I did not realize how off the last manual I sent you was.
If you replaced the IC's, where did you get the replacement IC's from? Do the replacement IC's have the name Sanyo on them? if not, that's your problem, you purchased aftermarket second rated IC's. Also you need to double check your soldering work on the IC's as it sounds like there may be a solder bridge or two.
Most likely you have a convergence IC that has failed and possibly a resistor or two. The IC's should be STK392-150's in this set. If you have severe line bowing I would look into one of these IC's being bad before alignment is done.

Here is the link to the user manual if you need it; http://service.us.panasonic.com/OPERMANPDF/PT47WX42F.PDF Check page 37/38 of the pdf file for convergence adjustment instructions. Page 39-41 for other colour adjustments. If none of those work, check if you have any other electrical items near the set that affect the picture if you move them or turn them off. maybe in another room. Hope this helps, please ask again if not:)

Ty Nog I have the user manual . Sorry But your solution did not work. Do you you know where i can get the service manual. i think it is an out of adjusment problem
ty techman I will try your solution, with caution. BEfore i start i will write down all the current settings. My Email is [email protected] By the way I am not an electrician. That part looks like an computer chip, does it just snap in or does it ned soldering to the board.
Igot the the STk's in now my tv just makes a beeping noise when I plug it in no pitcure or any thing please advise
