Re[3]: Convergence problems on AV-48WP30

Eric Posted Jan 02, 2006, in response to:Dave

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. Eric

    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

    Also Eric, Do I need to be concerned with taking the back cover off of my av48wp30? I have read about jumping some connections so as to not mess up the tv. Is this necessary? And if so, could you send me directions on that as well??? Thanks Again Don

    Mr. Television.... I assume after reading all of these posts, that you are 'the man' to help me out with this issue. My AV48wp30 had the heartbeat/no picture syndrome that seems to plague this set. I am not a television repairman, but I am a tinkerer. Would you be so kind to send me detailed instructions(step by step, if you have them) on how to remedy this. I am assuming that I will need two stk150's and maybe some resistors at a minimum. I cannot thank you enough. Don

    Hello there Eric; I know you have been bothered a lot already, but I am trying to help a friend of mine that has the AV-56WP30. I replaced both convergence IC's as the red would not align, however in doing so, I did not see any other damaged parts (actually the IC's looked fine too but I replaced them anyway) I soldered them in and the same problem exists. What else could it be, and did I already fry the 2 new IC's? Are you able to offer any help? I would greatly appreciate your assistance. Vicki

    I replace them with STK-180 but no vision showing now. What can I do please ?

    Same convergence issue, I thought about just buying a bunch of 3d glasses instead, doubt that would work....any info would be greatly appreciated, thanks....

    I seem to be having the same problem as everyone else... Could you please email me the repair manual as well? Thanks a ton.

    Anyone needing the STK392-150 I have two that are brand new and purchased. I am getting rid of them since I got the wrong part for my tv. Email me and I can make arrangements to ship them to you.
