My Akai home theatre has no sound, the model is ATR-7016 EXB

Hi there,

I have an Akai home theatre system that just went on the blink. Radio channels all display but no sound. The transformer goes nosiy after 2 min, but the supply voltages stay present. The audio amp Ic's does not seem to get hot, as if there is no supply.

Could you help?

  1. Sounds to me like you have a blown amp, or preamp stage in the receiver. Depends on how much money you want to sink into it, you could get a service manual, and start there. In my experience, HTIB systems are rarely worth fixing, as the cost exceeds the price of a new unit VERY quickly. It sounds like you have a multitester, you can check the speaker lines for continuity, and any sort of voltage output to see if you have a damaged amplifier. If the Preamp/input, and Amp stages are on separate PCBs, you can also test for voltage across the two.
