Re[2]: Convergence problems on AV-48WP30

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  The DCU or Digital Convergence Module MD001 is JVC Part # QAL0382-002 which is showing as NLA but has been replaced by QAL0382-004.

    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?

      The "silver box" is the DCU or Digital Convergence Unit. It stores your convergence settings and sends them to the Convergence Out IC's when the set is powered on. It is also quite costly so before I'd replace it I think I'd recheck the STK's and the resistors. The tolerance of the resistors is very important. They must be within 5% of the value listed. Also, sorry to say but there are a lot of bogus STK's out there. Be sure to purchase them from a well known distributor.

      Jamie Forgot to mention, did you try the Tech Adjust Method, rather than the Customer Adjust Method?
