Marantz PM7200 Amplifier, wont switch on, no power light. Changed the plug fuse, checked the fuse inside, looks ok but not got a spare to change it.

ask the repairman what the deal is

Try wiggling the speaker cables where they connect into the PM7200. If it crackles get the shop to check for 'dry joints' in the unit. It is quite normal for things to look ok and to work perfectly in the workshop, but that is not a good test. Dry joints are quite difficult to spot and any soldered joint 'looks' ok, but if the soldering temperature is a bit off, usually on the low side where the solder is only just about hot enough to melt, it will result in a what we call 'dry joint'. It is not unfrequent to get this problem with production line processes as there are many factors on the assembly line that can effect the tip of the soldering unit. It can be as simple as someone getting up out of a seat and changing the air flow that then causes the soldering tip to cool slightly. We are taking 'parts' of a degree temperature changes. The shop should have equipment to test the conductivity of soldered joints. A light hand during testing is a prerequisite!

The top link is for a manual for your model. The second link is a Fixya link concerning "no power". I'm not sure why you are looking for fuse but, have to assume it's a no power issue.

hi,
First of all check the power at the socket to which you have connected the amp.If you are not aware of electronics, then do not go for a test with an amp like KI signature.
it will have a fuse in its inside. its only blow off if there is some fault inside the its circuitry. consult someone who is well equipped for the same.
ok

The preamp stage might be dead. Not much you can do but to bring it in. Make sure the input selector is on the right input.
Sometimes there's a "Monitor input" usually Tape2 input that overrides everything

it sounds like your power surged maybe and it fried it check on the circut boards and see if you see any black spots like burns

Could be a power supply failure or a Power "On" switch failure.

Pull cover check for fuses on the bord and replace with exact rating on the fuse.

no! you got shorted or leak capacitors, and change value resistors.
