Most likely cause of a receiver shutting off when turned up is a bad speaker or speaker wire.
As far as having to turn it up almost all the way, that is the norm on most new receivers today. Most receivers no longer have a true preamp section, which means you have to run the main amp much harder in order to get a decent sound level.

Personally I would use an RCA cable and hook up the AVR.
((RCA out of TV to AVR audio in))
((cable box HDMI cable output to TV HDMI Input1))
(As far as the AppleTv I would use a separate HDMI Input2)
If your AVR has a dvd or blue ray player Hook up a
HDMI cable out to another Input HDMI3 of the TV
using separate inputs on the tv will allow your surround system to be
used on all modes(CABLE,DVD/BLUERAY,APPLETV)

If you have done a Denon reset and you still get the same thing, the hdmi/network pcb which is on the same board as the hdmi is defective.

Is the TV connected to the receiver with a digital connection (coax, or optical)?. Try setting it to PCM on the TV Some receivers don't like it when there is a break between tracks and the signal is lost. You won't get surround (but Pandora is just stereo anyway), but you can still use the Receiver's Dolby or DTS features to go multispeaker. Downside if of course that if you have other Multichannel audio sources through the TV, they may be lost. But it's worth checking..

There is no 'display fuse'.
Fault find the power supply and microprocessor.

After you have set your clock time simply just hold down memo button and I goes to minutes and click memo once to save your chosen time.

I expect your tuner/amp has a fair number of ultra sensitive CMOS devices inside and a power surge is likely to be instant ***** for them - if the surge reached them.

Any piece of equipment that has a computer inside really should be protected by an anti-surge device.

Your Denon tuner/amp is a bit of really premium equipment and I advise you it is best to entrust it's resurrection to a Denon approved repairer.

if you want to set your playback speed exactly right, you need a test tape with a test tone on it (3khz for example). now you hook a frequency counter to your tapedecks output and set the speed accordingly.
