There are a few technical issues which are very common we found in Marantz AV receiver amplifier SR6014 that we will discuss here:- 

Symptom:- No power, red LED is not getting on, System Dead, the system is not turning on, No display at all 

Solution:- If there is no power or no LED light or no display then 1st you need to check the power socket by changing it with some other device, if another device is working fine in the same socket that means the power socket(AC line voltage) absolutely fine. Now you need to check the power cable which should be connected firmly to the AC power socket of the Denon AV receiver which is built at the backside cabinet. If it is connected properly that means the system has technical issues which can be solved by doing this, just remove the back cabinet by unscrewing the 8 screws, then check the power supply PCB (circuit) which is built vertically at the AC power input section/side, then check the main fuse, if it is blown then change the main fuse with the same value( fuse value is measured by Ampere) now probably your system will turn on and your problem is solved. If the fuse has blown again after changing by new one within a fraction of a second that means the power supply circuit(PCB) is short and you should visit the authorized service centre to check/ change the main Switching IC, bridge rectifier diode, main filter capacitor, 4148 diodes, quarter watts resistor and few low voltage Zener diode. After doing this your power supply will be absolutely fine and your AV receiver/amplifier will work like earlier.
