Im working on a Sunfire HRS-8 that suddenly decided to stop working. No power or standby light. Its not the usual humming, pops, etc that affects many Sunfire subs. Pulled the plate amp and everything seems normal accept there are afew SMD resistors on the standby board (one in paticular that looks charred). I cannot read the resistance and was hoping someone might be able to sneak a peak at their amp if they have one available. The resistors in question are R438 and R439 on the standby board...R439 appears to be the worst shape. This would be sooo much easier if carver would just publish the schematics. Pictures attached. Thanks

Thanks for the reply, yes I did pull and test those 2 resistors in question
R439 measures 260K ohm out of circuit
R438 measures 565k ohm out of circuit
They are not open but I cannot imagine that those are the proper specs. The both look like they felt some severe heat. The sub will not power on and I suspect the issue lies in this standby board.
