Hello, the most used buttons can wear out over time. On/standby and volume are the ones that are used most often. I suggest purchasing a new remote. It is available at shoponkyo.com. Thank you, Onkyo USA

Sounds like you may have a bad HDMI card my friend. I had an issue with my HDMI card that was causing blue dots to appear on the dark parts of the screen, when outputting 1080p over HDMI. This is a rather common issue, so it wouldn't surprise me if your HDMI board needs replacement - especially if you've ever experienced the infamous blue dot issue.

If you have warranty left I would encouage you to use it because you clearly have a problem, the cable has been changed along with connections checked. The only other thing is check your setting carefully on both units to ensure nothing was missed, "owner manuals would be handy"

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Unless you are good at soldering have the parts on hand and know exactly what you are looking at, it will be very difficult for you to fix it yourself.
