I've included a picture here of the board with some of the burnt posts indicated.

You have obviously not read this whole thread. No big surprise, it's a long one!
Those are the big resistors, and were added later. That's why they still have the rosin on their conn's. Nothing wrong there. If you don't see browning of the top
of your board, under those resistors, you know there's been no overheating going on.
But you gotta STOP USING YOUR SET NOW
. Otherwise you're playing Russian Roulette with it and are just looking for trouble. Unplug
it until fixed correctly
. Do not
allow it up to normal operating temp again until this sit has been remedied completely
Send it to me and I'll take care of it permanently. Survey this thread and you'll see that I've been on this like flies... oh, you know! for years. Or if you're a qualified professional do it yourself. But don't farm it out to local repair techs, who will only band-aid it and you'll be right back where you started within a year.
My resoldering jobs on these boards are permanent. Contact me directly - no pms please! - and I'll get you what you need, to save your set. I only have 4 boards in the wings right now here, awaiting my attention. It's been worse, I have at times had 7...
