Okay I can't take it any more. My Sony XDR-F1HD tuner mysteriously turns off constantly, sometimes after just a couple of minutes of use. It will work for a few minutes and turn off again.
Sometimes it goes for hours without shutting off but lately it won't run for more than 20 minutes. I know that there are overheating issues with the tuner and some have placed raised feet on it to allow better airflow. But has anyone had one that turns off constantly?
Did it turn off due to overheating and that's what prompted you to place it on raised feet?
It will either turn off completely leaving the clock screen on, or it will just stop producing sound even though the radio station frequency is still displayed. In the latter case I can tune to another station and it will start working again and I can go back to the previous station I was listening to.
It is not hot up here in the north yet so I can't believe that it is an overheating issue.

Thanks.

I usually leave mine on all the time and never had any issues with heat at all. It's on a rack with lots of space for ventilation but that's it. No mods done on it.

Thanks. I can't believe you can leave it on all the time.
Perhaps I don't have an overheating issue but something else.

I just put my hand on it. It's warm but not hot and it's 27C outside and I have no air conditioning, just a ceiling fan in that room. I think it did lose sound once for no apparent reason and I had to turn it off and back on. That was ages ago.

Hello:
These are known to run hot on the power supply board. Heat significantly reduces lifespan of electrical components especially capacitors. That's the first place I would suspect for what you describe.

As these tuners are irreplaceable, I have added some spacers to the feet to raise the height. This allows for more air circulation through the tuner. I also run a small computer type fan (at reduced voltage / speed) placed over the top vent to draw the heat out.

If you check out audiokarma.org there are a couple of guys that work on these. Perhaps they could offer a solution.

Good luck.
