Re: Convergence problems on AV-48WP30

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.

  Do you know the name for the DCU (AKA) for JVC AV-48wp30.
  
  Thanks!

    The DCU or Digital Convergence Module MD001 is JVC Part # QAL0382-002 which is showing as NLA but has been replaced by QAL0382-004. Eric

      Is this the silver box on the board? I replaced the STKs and the resistors and now can adjust the convergence, but there is a wave in the red convergence along the top of the screen that is particularly bad at the top right corner. Also, the bottom lines of the grid don't exactly line up either. Do I need to replace this part too?

  Do you have a pdf of the Service Manual for a JVC AV-48WP30 you could email to me? Having excessive red bleed down in top left corner, convergence adjustment will not fix. No speakers closeby. Thanks so much.

  • Re[3]: Convergence problems on AV-48WP30 Eric - 1st Jan 2006 16:14
    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

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
