HELP MACH 1000 WONT TURN ON
 

I can feel the stock and the after market stereo power on but nothing on display and can’t get to accually “turn on” I feel it whirrr in my hand but I can’t get it to accually power on and play anything I’ve bought a DDIN jvc and I can’t for the life of me get the stereo going. Car sat for years till I rescued it from sitting in a yard for years got everything working except.. yup u guessed it my stereo. Best Buy dude knows as much as I do on stereos so they r useless and I can’t afford to pay for another installation plz help me fuses r good no engine or battery lights on in dash idk what to do I’m stumped
