Unit comes on then shuts down; fan rotates once. Is there a fuse?


Its an indication that your system is overheating and a short circuit exists so the shutdown - disconnect all inputs and speaker connections and switch-on if still the same happens then the system has an internal error

Marantz 4220 Power Switch Dear experts Some time ago when unit switched on cracking noises in speakers started. But now exept ligting up no sound is comming just little when volume turned up.What could...


The Amplifier was failing and that's why you were getting the crackling noise.

Most receivers have an Auto Protect that shuts the system down and goes into Protect mode at the first signs of failure or overheating, usually indication by 'Protect' on the display.

I'm presuming from your post that you never got any indication that the unit was shutting down to protect itself and has just failed, so I'm presuming that this facility isn't fitted on this model.

Depending on you Technical ability it could be an easy repair (replacing the complete PCB or some PCB components). Your only other solution is a visit to a service engineer.

My yamaha rxv595a keeps on shutting itself off when im watching movies as soon that it gets loud it shuts off but its not even that loud how do i fix this problem i tried the ohms switch in the back and it...


That is a safety switch in most receivers. When something gets too loud it cannot give the load off to the speakers and shuts off to protect itself. This can mean that the receivers getting old, or that you might need to split the job. You might need an stereo amplifier to split the job. Check the cables and speakers. Recievers can only give so much to so many speakers at so much sound. That is what the whatts are for. The more whatts the better, the lesser whatts, the lesser speakers its going to be able to handle at high volumes.

30 seconds after turning on the unit, the screen flashes "protection" and shuts down. the manual says this can occur due to overheating or a short in the speaker connection. This product has been...


Hi,
Actually, as unlikely as it may seem, the problem may actually be with with the speaker protection circuit design, or of course, the unit may be defective.
The unit may have an overheated power supply transformer, if it is sitting on a surface that blocks it's lower vents, such as a carpet, or if there is something on top of it blocking the vents, or if is residing inside of a closed cabinet, it could overheat from lack of chassis ventilation.
If this is the case, shut off the power, remove the obstruction, or relocate the unit.
Note: Your unit puts out over 600 watts of pure power (probably equal to thousands of "watts" of Car Audio energy. With very high efficiency speakers such as used in the old movie theaters, it would have been enough power to overdrive the system in a theater that had a capacity of 5000 people while blasting them out. So don't touch the speaker wires when the unit is playing loudly. You can get quite a jolt.
Anyway, check for chassis ventilation factors, connect up the speakers and see how she does.
I hope this helps you,
Best Regards,
Mark

My receiver shuts down frequently , wakes back after 2 or 3 sec .


do you have sufficient space around the unit? If it is in an enclosed space, has other components on top, etc, you may be overheating the receiver. Once it gets too hot it can potentially cause the issues you mention above.

If you have other components on top, try moving them to another shelf or below the receiver, and if you have a door on an entertainment center, leave the door open to help with air flow.

My creative zen mirco has a firmware problem and keeps going to recovery mode ??


Try the recovery tool from here (this is relevant to your recovery mode question also), but not all mp3 players will work with Windows Media Player 11 - causes a DB corruption - roll back to Windows Media Player 10 if this is the case:

I have uploaded mp3 music files onto my creative zen v, but on the player no information of artist is shown,just lots of track 1's, 2's 3's ,etc.When i check my media files,the folders are all there with...


the zen only keeps what info is needed to allocate the space in an mp3 player the tracks are numbered so you can add more
names take up alot of allocated spaces

also with a zen back up your files and do an update for mp3 player remember its a storage device with a micro chip they still need software to run properly
