Question about Technics SA-DX750 Receiver
After approximately 80 minutes of watching TV (regardless of the source), my Technics audio receiver will have moments of "mute" of approximately 3 seconds, at regular but increasing intervals (more and more frequents). It starts at once every minute or so, and increases to once every 15-20 seconds. All my devides are plugged in my TV via HDMI, and my TV is connected to my receiver via an optic cable. If I leave the TV speakers on, they keep going when my receiver stops, to the problem is either in the cable or the receiver. Since the problem is agravating after some time, I'm thiking overheating. Defective fan, maybe? Thanks!
Hi i just would to know if you did try to connect your TV by HDMI to test if your optical output of your reciever/amplifier have some problem. In second time yes maybe you can have an overheating problem, just take a look at your grid and maybe a clean-up will be necessary. I don't think your amplifier have a fan.
Don't hesitate to contact me here in this post. have a nice day.

Testimonial: "Hi Fabrice. Thanks for your answer. Did you mean "optical input"? My cable terminal and PS4 are connected to my TV via HDMI, and my TV is connected to the amplifier's input via optical cable. So you suggest connecting straight from the cable terminal to the amplifier via HDMI? The fact that the problem only occurs after approximately 80 minutes, and then repeats itself, made me think it couldn't be a cable problem. I don't know that I cable can get "tired" - stop working after a long use. I might not have selected the exact same model of Technics amplifier, althought it does look the same, but my amp does have a fan. It's attached to the rear left side. I can see the paddles/blades and they don't seem to be turning."

If the only thing not working is the optical input, it is possible that the optical converter is defective. Without seeing the actual unit and testing the IC, I can't say for sure. If you have test equipment, let me know and we will attempt to track this down.

I went to the HDTV plasma manual. It stated the only way the digital optical audio output would work (from this TV) was to go to the menu, select audio and turn off the TV speakers. Basically, it had nothing to do with the technics receiver.
