  Check\Replace IC804 STK392-110, which controls Red horizontal/vertical convergence. If IC804 is defective than replace both Convergence ICs (IC804 and IC805). I suggest upgrading to two STK392-150s, for better tolerance to heat. If IC804 shows visual damage then check resistors R843,R842,R847 and R846.

    hi Eric, This must be JVC season, I'm having the same convergence problem with my 48WP30. Can you send me the schematic and service manual, too? Thanks so much! James

      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. Eric

    Hi eric I know that if you got 1$ for every email you received about the av48wp30, you would be a very rich man! Could I make you a dollar richer ( so to speak ) by asking you for the same thing that everyone else has asked you for? Are they hard to replace? I will take your advise too upgrade to two stk392-150. How do I locate them in the TV. Can you give me a play by play on how to repair this. Thanks a million, John

    Hello, I am having the exact same problem with the red convergence for my AV-48WP30 . I can move it up and down, but can't move it right or left...The blue convergence is fine. Could you send me the manual & schematics to fix the problem ourselves...The nearest JVC Electronics Technician is over a half hour away, and it's going to cost a lot of money. And where would I be able to purchase the parts for it. Thanks
