SONY TA-D905 no audio

[b4nd1t]

I have a sony ta-d905, stored working, after a few years I turned it on and there is no more audio, indeed it is heard very low, from the speakers and headphones the result does not change.
Has anyone had experience with this amplifier?
What could I check to get an idea of what to do?

Thanks

Re: SONY TA-D905 no audio

Start cleaning all the buttons and knobs. Last time I had a no audio issue on an amp and the protect mode was not triggered, the problem turned out to be the tone select button.
You got to figure out on which stage you loose the audio. If the protect mode sent triggered, your problem is in the very early stages. Try using different inputs and settings…
