Re[5]: Convergence problems on AV-48WP30
Eric Posted Mar 01, 2006, in response to:Troy
Check your e-mail . I sent you the manual.
Remove the convergence board and check IC804 and IC805 (STK 392-110). These are the convergence outputs and have a high failure rate. If you replace them, do replace both of them and it would also be wise to upgrade to an STK 392-150. The STK 392-150 will run a lot cooler. Also, check all the 1 watt and 2 watt resistors on the convergence board for overheating. This is indicated by a dark ring on the body. If you have an ohmmeter and can check their actual resistance, better yet.

Ref: JVC - AV-48WP30 Hi Eric, I too have the Red Convergence problem. It went out yesterday and the warantee has been out for a month. I found the little white button inside the front panel. I got in to the service stuff, but could not adjust the red under any part of the system. Could you send me the manual/schematics too. Too bad they don't have a recall on this. It seems that a lot of people have this problem. I really do like the set. I must have looked at 40 sets and kept coming back to this one. Thanx, Ron J

Thanks Eric for the usefull information. Is the STK 392-150 is the upgrade version or just a possible replacement?
Thanks
