I get the same readings constantly now .
R156 1 terminal has 11.13vdc the other has 50.6mvdc
Q21 gets hot fans run nonstop

Confirm the voltages on Q21. With those voltages, it would be odd for it to heat up.
Did you reinstall R1?
Did you reinstall R1?
When r1 is installed q21 heats up .... r99 starts burning to c15, and fans run nonstop, so r1 is not installed currently
Q21
B= 11.84vdc
C= 153.7mvdc
E= 11.82vdc

I really appreciate the desire to do and learn, but to make certain repairs, you need to have a certain know-how.
What "know how" don't I have thats required for me to LEARN? It's my first time without a wiring schematic or any available information and so i looked for help to learn, my mistake i wasnt aware we had to report to you to see if we are worthy enough to post. You have done **** all in this thread to assist but are so entitled you think your opinion needs to be heard and that your opinion matters, news flash it doesn't.
I've more than admitted I'm out of my depth but someone's been nice enough to continue to help me so I'm going to take advantage of that and learn as much as I can sorry if that bothers you for some reason it's not like u have the choice to ignore this thread or anything but that's too hard for an entitled person I know. Your opinions must be heard I get it.
I'm sorry you interpreted my post as a criticism, unfortunately it is not.
I've been following the whole thread and I've noticed that every time you've been asked to take a specific measurement, you've taken another one, creating a lot of confusion.
For quite a few posts there was confusion between "MC1" on the amplifier and "IC1" on the LED board, this made it very difficult to understand what you wanted to check.
I don't want to say in any way that you are not able to repair an amplifier, but I can say with great conviction that these types of problems are perhaps a little out of reach and therefore it would be better to rely (at least for this time) on qualified personnel, since it seems to me that during your tests, other events also occurred which will have surely caused more damage.
The DIY AUDIO community exists to support each other, but (humbly) I believe that there must be predisposition from both sides, otherwise it becomes dangerous; in these appliances, sometimes very high voltages run.
That said, if you need help, everyone (including me) will definitely help, but you have to be very careful, for your own safety.
