Synergy Audio WTF 7.1D

Can’t seem to figure out why both 12 volt regulators are not working on only getting 0.4 volts on the output leg . Black probe on middle leg .


If you need more pics I can take some .

Any ideas ?

I tracked it back further and found 2 shorted transistors marked A1715

Do you know of a transistor I can use in there place to further test ?

Ok that cures that now the regulators are producing 12 volts .

Next question is there was a resistor badly burnt that connects to the negative speaker terminals.

There is another 10k resistor that also connects to the speaker terminals .

Would both of these be 10k do you happen to know ?
