- Own one unit TX-8220, powering on all buttons are functioning, no sound from any inputs, from time to time the message
DAB Reboot!
That shows on the display about every 30 seconds,
Need help on this. No service manual in hand,
Useless to say, reset to factory defaults was performed.
Thanks in advance for any help provided

I've never run into this before. Have you called Onkyo support? I suspect a bad board.

bad flat cable connections to FM/DAB tuner module.

Nice day everyone.
