You need to use a preamp for the turntable.

You must first check to see if the optical sound is an option on both the reciever and the item going into it, then buy the wire and it will plug directly into the ports.

No, it's in trouble.


Generally speaking, an amp protects 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. Eure 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.

Try this and let me know. First unplug the unit. Plug it back in. When you first push the power button, you should hear 1 click followed by another withing 5-20 seconds. My guess is that you don't hear the second click. Am I right?

You have this backwards. Applicable code(s) will be found in the remote control, if it is compatible.
