Yamaha RX-890 when I turn up the volume it turns off

you need to set up the individual volume levels for each speaker.
do a sound test tone which will check for a signal from each speaker.
if you hear the speakers at different volumes you know you need to adjust the ones that are too weak. hope this helps

Using 1056B03 universal remote from Time Warner. Several codes actually will turn the unit off and allow volume control. Or..I can turn on and volume control. Can't do both. I tried to use the receiver codes in the vcr mode, but the remote rejects receiver codes (i.e. only accepts vcr codes).

It looks like one or the other, not both.

I had the same problem with HDMI input to the RX-V373 from a DirecTV receiver. The RX-V373 volume display and menus on the screen are HD only, which forces the monitor to switch modes when viewing SD.

My solution was to turn off 480i and 480p signals from the DirecTV receiver, and also turn off its native output. The DirecTV receiver then upconverts SD signals to HD. Changing RX-V373 volume then doesn't affect monitor video mode.

If you look in the manual on page 37 it explains the Mute button and that flashing indicator. Item 11.

Page 48 under Set Menu:

Initial volume INI.VOL.

Use this feature to set the volume level when the power of this unit is turned on.

Choices: Off, -80 dB to +16 dB
Control step: 1 dB

If you are using the remote to raise the volume of the unit, my advice is to forget that function, and turn volume manually. I had a similar problem with a Sony receiver and the solution was simply to put aside the remote. Remotes are infra-red based, and if you have other components with infra-red this can cause undesired interference and malfunction. Good Luck.

Try to disconnect speakers one by one and see if any of them causes the problem.

Here's your manual. Hope this helps

You can find fuses near in the transformer.

Hope it may helps;

It just started working again. Maybe it took the day off.
