SOURCE: sony home theater system started blinking protect

Protect mode will kicking whenever a fault is detected.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Regards.

SOURCE: Power turns off

Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Stereo cuts out at half volume.


You don't exactly define what "cuts out" means.... silence, protection or power off?

What makes you think it's thermal in nature?

Have you considered the speaker load impedance may be too low for the amp?

F61 is a problem with the output amplifier pac. It is the equivalent of "protect" mode. The output pac needs to be replaced. I'll look up the part number for you.

Sounds to me like something burnt, maybe a fuse, Capacitor... Without opening it and running test it would be hard to determine the exact source of the issue. If you are using a power bar try it without.
