Samsung HT-Z310 Help please "protect"

I tried the black lead in a few spots the neg pin of c24fl, the gnd pin on c7 plug and the corner screw hole that's earthed. All gave the same readings.

That's enough to prove that the AMP board is definitely defective. 12 volt power rail has a low resistance to ground.

Seeing as most parts on AMP board are surface mounted and require a reasonable amount of desoldering/soldering abilities ... next step in this direction would be to start isolating any audio output IC pins that connect to the 12 volt source (3 ICs - 5 pins each). ICs here

IF a GOOD replacement board can be obtained, that would be the easiest way to go about curing here for one.

I cannot vouch for the emporiums mentioned, nor did I confirm stock.

Let me know what you decide.
