Thanks for all the advice guys, if it winds up being the optical block,
Tritronics says I need authorization to purchase. Do I have to call Sony
first, I am not an ASC for Sony, is that going to be a problem? Just want to
know before I head out to the guys house tomorrow with some probable BAD
news.
