Thanks for that. I guess I didn't think to even search for that. Though I did try to find info when I first saw it when recapping but came up empty handed. I guess the residue isn't anything I need to be concerned about as it is essentially just the flux left on the board reacting with the chemicals.

Even so it still made me nervous so I went ahead and sprayed each board down with Lysol all purpose cleaner and went over them with the acid brushes. This instantly took away all signs of white residue and it actually dissipated pretty quickly. This stuff is a degreaser and soap scum remover. My only guess is the soap scum remover part of this is what is helping here.

Anyway I let one board dry under a fan and everything looked fantastic. To be sure though I did every board with the Lysol all purpose then gave each a quick dip in the isopropyl bath to repel any water and set them out to dry. This seems to be the magic recipie that works for me.

Hello everyone. Just wanted to stop in to say that I am still working on this. I was able to get the burnt transistor replaced but still no joy. luckily someone was kind enough to send me the service manual so hopefully at some point this weekend I can thumb through and do some quick voltage checks to see if everything looks right. I suspect also that a capacitor still might be the issue. There are a few of the very small ones that I have yet to replace but figured with all the main caps done I should at least see some change. Well I didn't but I do realize that it only takes one so I will be back at it soon. Any words of wisdom or advice here is always appreciated so don't be shy. See you guys soon.

Keep plugging away, you will get it. If not Andy can help. Good luck with it.
