Re: Convergence problems on AV-48WP30

Eric Posted May 28, 2005, in response to:Mark Venable

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

    I also have the "sagging" red convergence problem. Is there a chance that someone could send me the guide and part numbers? Thanks very much!

    Convergence problems on AV-48WP30 Thanks Eric Thanks Eric Your files were a major help. Had a problem with Blue Convergence, you sent me files and assisted with some helpful information. Replaced IC chips and TV works great. I did try a little upgrade. The convergence chips are 0.10 centers like normal IC so I purchased some IC sockets. The Hybrid chip pins are standard spacing but not standard diameter and the pins would not fit in the sockets so they had to be hard soldered back in. A good solder removal tool is a must for this repair. Thanks again Eric. Mike.

    Eric, You seem to have an excellant understanding of this TV. My problem while similar, is a little different. I am able to adjust the convergence crosses vertically and horizontally and achieve a white cross. My problem is the left top cross sits lower than the other crosses across the top. the left top portion of the screen is slightly out of focus with some halo effect and straight lines are distorted. Any help you could offer would be much appreciated. Regards, Don Vaughn
