Sony Sound Bar - SA-WCT380 - No Sub Woofing.

Hi Bruce,

Fortunately Trump isn't calling, as Norfolk is just a blip on the East side of England - Mind you, we have some nifty golf courses though. Not tried any as the whole idea seems pointless - Rather buy STR chips and pop 'em, as at least it's fun, whether or not.

Invariably use a series lamp if dubious, but seems the STR went the same way as original, into a sort of 'sulk mode' popping nothing, but never to go again.

Not too keen to replace the chip, but chums have said I should get a pre-heater, so with a whiff of heat from the top, can lift it off.

Admit getting a chip off was never a problem as just flipped legs one at a time. Issue seems replacement where solder spreads about a bit. Tried 'Gull Wing' bits and solder-mop, but solder just seems to congregate where I can't reach it.

Thought try use solder paste, but it's messy and the chip slides out of sight along the panel - Fun though - Chris.

Thanks 'Cat'

Seems the woofer SMD class D output chip if duff, as it's killed two STR P/S chips. The short blows two supply fuses but the STR doesn't recover, though it doesn't go S/C and pop the mains fuse.

Got the output chip on order, and when have the courage, I'll have a go replacing it - It's the size of a flattened pea with a lot of pins, and seemingly rated at 250 Watts - Nifty - Chris.
