I saw Quick chip on Amazon when I ordered kapton tape and I was like no looks way to good to be true .... ill have to grab some ..... I'm positive I broke that trace it's way to fresh and clean looking ....
That would men that the resistor is defective but I don't think it's accurate.
The resistor should have 12v on one terminal.
What's the DC voltage on the amp's remote terminal?
Do you have any scrap computer ribbon cable?
Any adhesive like GOOP or E6000?

That resistor is fine 2.2k ohms resistor I checked it against has 2.19k ohms I had meter on wrong setting forget its not auto
Remote voltage at main terminals 12.34vdc
Could led board not installed be an issue?

I don't know. The readings up until this meter have been useless and I don't know, at what point, you removed the board.

I have scrap television screen cable almost the same I think I may have e600 I can go look ... I definitely have fix all adhesive (like goop) and mukri purpose rubber cement next to me
I removed it 2 mins before I posted the pics after our tests ... I shouldn't have I apologize
But ever since the day I was taking readings and r99 starting smoking and burnt trace I lost all other voltages to board... except q21 q22 area and power supply transistors

To repair the connection:
Scrape (gently) the trace somewhere that it's well bonded to the board and clean the area with acetone or alcohol.
Tin the bare copper area
Cut and strip a short length of a strand of the ribbon cable. Tin the ends.
Solder one end of the ribbon to the tinned trace and put a dot of glue/adhesive to hold it securely in place. Let the adhesive dry.
The other end of the ribbon will solder to the tip of the header on the LED side of the board.

Hey perry is it ok if I desolder r99 and take a pic a for you to see if it also needs repaired
The day I lost all voltages except what we've been testing r99 heated up desoldered itself from board I think it also might need trace work

Yes but didn't it measure 4.7 ohms?
That resistor is beyond Q21 and Q22 so it's not an issue at this point.

No good

From this point, on, if you don't read 0v on the emitter of Q22, there's no reason to measure anything else.
Until you can determine why a point (Q22 emitter) that reads 0 ohms to ground is reading 12v, there is nothing more that we can do.

DC voltage on both terminals of R156?
Can you repeatedly measure those voltage and get essentially the same readings?
What was causing the voltages to be wrong before?
