Model:

Fault:
No Sound

Remedy:

I opened and checked visually. Eveything seemed fine.
Then I focused on the main IC Model# PHILIPS: TDA8947J
4 Channels Audio Amplifier

I checked voltages at all of its pins. I suspected a dry solder, so I re-soldered all its pins one by one. The sound came back.

Lee Lay Sian gifted me the speakers & never took back.
