Convergence problems on AV-48WP30

Mark Venable Posted Apr 10, 2005

Can't adjust the red horizontally

Convergenge went out suddenly about a week ago. I can adjust the blue horizontally and vertically. The red will only adjust vertically. However, the horizontal is way out of whack. Any ideas? Thanks

    Sorry Guys I have been busy as of late, so I dont have time to visit as often. So if you want the help file just send Me an email with "Repair" as the subject. Later.

    I'M ALSO HAVING PROBLEMS WITH A MODEL AV-48WP30. NOW THE RED WILL NOT MOVE HORIZONTALY AND APPEARS TO HAVE A CONCAVE DIP IN IT. IT SEEMS TO HAPPEN AFTER SHORTY AFTER THE TV HAS BEEN MOVED. THE FIRST TIME IT HAPPENED WHEN THE TV WAS ONLY 13 MONTHS OLD AND I WAS STILL CHARGED OVER $450 TO REPAIR IT UNDER WARRENTY. 9 MONTHS LATER IT HAPPENED AGAIN AND WAS AGAIN CHARGED $450 TO REPAIR IT FOR THE PART BEING UNDER WARRENTY. NOW THE RETAILER THAT SOLD ME THE SET WANTS TO CHARGE ME $200 FOR ME TO TAKE IT THEIR STORE TO HAVE IT LOOKED AT. (THEY WILL COME PICK IT UP FOR AN ADDITIONAL CHARGE OF $75). ANY IDEAS HOW I MAY TAKE CARE OF THIS MYSELF OR JUST JUNK THE SET?

    Hi Eric, After reading all the posts I see that you're the oracle on troubleshooting this convergence issue. Do you think you could kindly email me the schematics too? Thanks in advance! email is abflex2@hotmail.com

    I am making a small guide to help you guys. Also use at your own risk. Ok.

    What are the part #s for the convergence chips on the PT-47WX34J? Can you get everything in a kit? Mine just went out completely unexpectedly, and don't feel like spending $400 to get it fixed, if I can do it myself. Thanks.

    I'm having the same convergenge issue where I can't adjust the red horizontally. Blue adjusts fine. Can I please get a copy of the fix sent to my email as well. Kindest regards, Bryan Moscato

    Excellent diagnosis by Carlos. IC804 controls red convergence. But in time IC805 will also fail as well. Replace them both with STK392-110. Also, check for cold solder joints in the vicinity of these ICs. If you want a schematic for this unit e-mail me. Eric
