If pin 7 was grounded and there was 10v on pin 14, it's almost certainly defective. The only possible way it's not defective is if 10v was being driven back into pin 14. I'd suggest replacing it.
what should i check when replacing the chip?
hi there, i'm new in here and need some help with same amplifier.
i dont create new thread and continue with this one.
HIFONICS bxi 1606d:
problem occured when i find out that my car leaks (some componets where wet).
494 works fine - outputs are OK, all mosfets seems to be fine, but hip4080 goes wery hot.
when i take out 4080, amp switches power-on stage (green) and when i put it back, LED switches to red...
what to do? replace only hip4080?
hope anyone answer...
sorry about my bad english

In many of the hifonics amps, the primary filter capacitors fail and can cause all sorts of problems. If the DC voltage across the power terminals is remaining above 12v, try connecting a 1500-2200uf capacitor directly across the power and ground terminals to see if that helps.
