My STR-DE345 has no sound from the center channel, and has not had it for quite some time. Any easy fix/diagnosis? Is there a part I can buy and replace myself?


The center channel on this model uses its own amplifier circuit that is independent from the others. It is usually a 5-9 pin IC attached to the heatsink. It is likely that this IC is defective and needs to be replaced. Unfortunately, I can not know this for sure without taking measurements inside the unit. There is no simple fix for this although this is an easy repair for a service shop. Please seek professional assistance to resolve this. Expect a parts cost in the $25 range.

My sony STR-DE345 amp says "protect" and there is


The manual says it thinks there is a short circuit on the amplifier output side. If it still says Protect after disconnncting all the speakers wires there is an internal problem. Take it to a hands-on tech.

If the problem disappears, you had a short. Attach speakers one at a time to isolate the cause.

Str de345 shuts down after a few and flashes (protection) on face of amp.


The Receiver is going into protection mode and possible some speaker cable might have touched the body or with each other.
Remove all inputs and outputs and then restart the receiver. If it starts then you are lucky and no further repair are required.
Connect all cable and wiring properly and ensure that they do not touch each other. You might have to reset the microprocessor also.

If the problem persist then let me know to further the trobleshooting.

Please do rate this solution and thanks for using FixYa.

Fuse keep blowing off


If the fuse keeps blowing, that is an indication that something has failed and is drawing too much current. Most likely it could be a problem with the power supply, such as a shorted rectifier diode or voltage regulator. Another possibility could be a shorted audio output module. Unfortunately, you'll have to take it to a repair center to be serviced.

Please let me know if I can help you further.

Good luck!
