Just a question for any mitsubishi service repair guys. My WS55807 has been in the shop for about 5 months. The latest hold-up has been replacing the signal board, part 930B868001. According to the shop the first one wouldn't fix some convergence issues and the second one was cracked during shipping. Now the shop says Mitsubishi is getting a lot of calls about the board and is holding all of them for additional QC. Is this true? I thought parts for these older TVs were no longer being made, so these boards should be coming from storage rather than new manufacture. I'm worried that I am getting the run around by the repair shop since everytime I call I get some excuse that ends in "..will be ready in a few days".
