I have related problem with ic2030.in My HIFI home theater,one ic2030 have blown and I replaced with the same ic,but when I hook the bass speaker the replaced ic become overheating, where as the other ic normal,what can you suggest me to over come this problem please!!?

Agree with lynn Blakely....just confirm for the short circuit of IC if not - take a chance.

I have the same question as well. Especially when a bad power IC could blow his newly installed component(s) again. Perhaps Suranga couldn't get his hands on a replacement IC and decided to roll the dice. But, from my experience, a blown MOSFET is often indicative of a signaling problem so replacing the IC is par for the course. Also, that IC could be failing intermittently. Works today... misfires tomorrow. But Suranga has a lifetime more experience at this than I do and is probably in no short supply of caps, resistors and mosfets to replace these with in case they did blow up again. But still I'd love to know what made you take that chance.

But let it be anything, when it comes to you, it would get a life and that is your creditworthy service!
