PROTECTIVE FEATURE

In some cases, the STANDBY indicator may blink slowly, twice per second. In this case, turn off the unit, unplug the power cord, and check the following points.

Make sure the speaker cables are not reversed and connected to the wrong sides (+ and -) on the unit.

Make sure the speaker cables connected to the unit are not shorted. (Check both the unit end and the speaker end.)

Make sure the volume does not exceed the level that the unit is capable of producing.

When using the unit in a rack or other enclosed space, heat may build up inside the unit and cause a fire. When installing the unit, be sure to leave suffi cient space between the top, back and both sides of the unit and walls or other AV components to prevent the internal temperature from rising.

After checking these points, plug in the power cord and use the remote controller to turn on the unit. Turn down the volume before resuming playback. Confirm that there are no problems with the speaker connections and playback performance.

If this symptom recurs, request service at your nearest service center.

In rare instances, the unit may enter standby mode and the STANDBY indicator may blink rapidly, 8 times per second. In this case, unplug the power cord and request service at your nearest service center.

if you have the blinking led problem on your SR4002 receiver, it is in protect / safe mode 1- turn on you receiver2- hold 'S speaker B' + 'ATT' + 'exit' buttons at the same time for 3 seconds3- it should turn back on normally

these a couple things you can try to reset,if resetting dont work you will have a amp problem.Try pushing and holding down these 3 buttons s.speaker b and att and exit buttons for at least 3 sec or more.should reset.If not also try pushing and holding down mult speaker and exit and att buttons together for at least 3 or more seconds.if still shuts down you will have shorted transistors inside of unit.

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...

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.
