I had what seemed to be a convergence problem so I replaced the convergence board (AWV1892) and now have the problem you describe. Anyone have an answer?

Convergence board cracked?


Once the board is cracked it is no longer repairable (even if it's a tiny crack that may not appear to interrupt any connections), and you would have to replace the complete board. Any attempt to repair or continue using a cracked board may cause more damage to the entire unit. You can find a replacement digital convergence board for a model # SD-643HD5 from this major Pioneer parts distributor at the following link:
