Marantz SR-7200 Goes to pure static and volume spikes

Check Speaker connections at BOTH ends and double check to see that they are on the right terminals.

If you need a manual . the Marantz site will have one . PLus they may have FAQ notes for that receiver

Cheers

Check for a burn resistor

if u want to sove your problem then contact me on my number 9555503717

For resetting sr6001: When power lights blinking, press "clear" + "pure direct" + "7.1 ch input" simultaneously for 3 seconds.

Change the audio amplifiers IC´s because are on short circuit

most likely the audio pre amp & volume control chip

Press AMP then OK on your remote. If the menue does not appear press 9 on the remote. You must have your monitor connected through composit Monitor Out or S-VHS.
Also check your multiroom settings. Maybe your OSD signal is diverted through to other room. I do not have SR-7200 any more, unfortunately.

It is likely that the PA stage has developed an offset voltage in the output stage. The faulty amplifier channel can be found by progressively disconnecting the collectors of the of the power transistors until the protection fault disappears. Once the faulty channel is found the the cause of the offset has to be traced to the faulty transistor or resistor. Don't forget that if you can smell smoke or burning then there are likely to be components(esp transistors) that have been damaged by the fault.
I had a Luxman unit that destroyed 5 transistors in the output stage that was due to an open .5W resistor in the driver stage.
Good luck.

The video switching on your receiver is bad. This is a sore spot in an otherwise excellent unit. IFfit is out of it's 3 year warr. the repair will be prohibitive so I suggest getting a video switcher and use it instead. Some of them can be programmed to work with the Marantz remote so you don't have to switch with 2 remotes.
