Katzman, thanks for sharing your repair experience with us, and glad it worked out for you. Your voltage adjustment attempt gives us a little pause in experimentation.
However, for some of us, we continue to seek answers because it is more of a hobby or the thrill of discovering something new. I can appreciate those who are conservative and leave things alone especially if they are working, but I more appreciate those who experiment and expand their knowledge. This challenge of finding a solution is what makes technology so exciting!
