hi guys I have the above MacBook Pro 16inch 2019 i9 32gb 1TB

and for some reason it won't always power on and I have to do a DFU to get it on.

and then when it is on it randomly shuts off and the fans hyper speed.

ive replaced the thermal paste and all is good

but it won't always power on.

and ive noticed I no longer have a chime ??

when I try to play audio the MacBook freezes and powers off.

and then powers back on eventually
