Hello, I too am from Cochin. If it is ok, can you share the contact details of your service technician? I have a couple of equipment that needs urgent service.

Hi, IC U1 is LNK624DG and U2 is IRS2153D. If blown you can replace and your sub will be ready to kick again, of course if rest of the things are ok.
