What would work better for Marantz SR 4200 Apple Composite or component cable? In order to play music through the amp as well as watching videos

screen tube /supply are defected

Try to reset to your Marantz to factory settings, or try the newest Firmware. :)

It takes two, maybe more to tango - plus the cables that carry the various signals.

Can you define the signal loss better? Where do you detect it?

Audio, video, both?
Optical, HDMI, component ????

Try a different input or output port on the Marantz to isolate the source(s) as contributors.

Simply run a composite video (RCA) cable to the TV.

I will interperate this as:
"So you want to play sound through your Marantz SR-4200?"

You need to clarify what sort of system setup you have, however i will put down a few ways to wire this up to your TV.

If you have a Set-top-box that gets the TV Channels, that is where the sound comes from. If you have a TV that plugs straight into the wall, you will have to get the sound from the TV. Grab a RCA Stereo cable - (White and Red heads, if you don't know what they look like, Google it).

If you are unclear about this, i have tried to make a diagram down the bottom to explain how this is to work. What you will do is Take the sound from the Set-Top-Box or TV and reroute it into your fantastic Marantz SR-4200.

1. Plug Red Plug into the the Red Slot, and White into the White on the back of your set-top-box or TV Out (if you get it around the wrong way, the speakers will be reversed.)

2. Plug the other end of the cable into the back of your Marantz SR-4200 in the TAPE input or VHS input as they are analog signal inputs. Turn on Marantz SR-4200 and turn it onto Tape or Vhs (depending on where you plugged it in).

[Set-Top-Box or TV out] >-------> into >------> [Marantz SR-4200]

If you still don't get it, then try searching You-Tube for a guide "Plug Tv into Stereo". I myself couldn't turn up anything useful

i also am looking for the file on the owners manual for the marantz SR301 can anyone tell me where to find this download?

This is an indication of some bad solder connections on one of the boards. It could be the power supply board, amp board, or the digital board. I would like to be more specific, but this is not a common problem with those symptoms. Bad solder connection are a common problem and can cause many different unusual symptoms. Unless you have excellent soldering skills, it would be best to let a service center repair this for you. This is a very good receiver and is well worth getting fixed. If you have excellent soldering skills and are willing to take a chance on fixing it yourself you could save yourself some money, but be aware that if you make even one mistake while soldering, you could easily cause much more damage than you started with. Some of the components that may need to be resoldered are surface mounted IC's that are very difficult to resolder and if you have never done this before it is not a good idea to start learning how to solder on such a nice receiver.

Let me know if you need any further help.

Go to amp set up menu and make sure it knows the cables you are useing,ie-if the dvd is wired with coax for sound go to input set up and tell the amp you are useing this type of cable.If this is not the problem and the sound is going off one device at a time your amp needs to go back to your dealer.
hope this helps.

please invert your cable and watch if the problem moved the problem in your cable change it with new one.from any radio shack near you or any electronic store.
