Pull the power for about 15 minutes, then plug it back in and try it again, if still no work, then you need to get it looked at by marantz...

Marantz sr4002 - Power light blinks but power will not come on. Tried the reset trick and no response. ???

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 'nekkid'. 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.

Power is connected to unit. Flashing standby but will not turn on. Marantz SR4002 receiver.

The unit is in "protect" mode. This means that there is a problem in the final output section. The most common fault is bad output transistors. Expect a parts cost of abput $15-$30 in parts plus the local labor rate for a repair cost.
