Marantz SR-18 SR-19 Repair Service
Typical problem- no sound. The unit powers up, all functions work but there is no sound at all.
Most likely one of the channels at the power amplifier module is blown. It caused protection circuit to open all speaker relay and disconnect all speakers from the receiver.
Why it happened? Because of bad/cracked soldering joints in power amplifier section, the amp can not control its DC and output transistors current. It leads to blow output transistors and surrounding components.
Usually it doesn't matter how hard you push the receiver. Its just matter of time if the receiver had never been in a repair shop.
Now we need to repair that blown channel and refresh all soldering joints to prevent similar problems with other channels in the future.
Other common problem with the receiver- it lost all setting when you unplug it just for couple minutes. Right? We aslo will fix this problem for you.
The service will not cover water damaged, fire damaged, DIY units, unit with mechanical damages and missing components.
