Hi boltbob

Strange one... . The unit has'nt just lost its presets for optical input selection by chance. Most receivers have a volatile memory for user presets that can reset input settings to default when the unit has been unplugged for a period of time. This may mean that your amp is not looking at the optical inputs for that source. If it has correctly selected the optical inputs, then something common to all optical inputs has failed, maybe a a buffer stage between optics, D/A or Source switching stages.

Try disconnecting the unit from the wall socket for 10 mins to do a hard reset and see if that has any resolve to the issue.

Other than that, its out with the multi meter anbd do some DC checks about the optical , buffer and d/a stages. Try the reset and let me know how you go.

How much breathing space does a refrigerator need NONE, 1/2 inch or 1 inch above the top of the cabinet for air circulation. Sears has told me all 3. WHICH IS CORRECT?

For airflow it would be the back that needs clearance of a couple inches. Top of unit shouldn't matter. Inside the fridge itself if you plan on packing it as full as possible except for the amount space needed to allow airflow,. I would just atleast leave 1 inch on every side. But outside of fridge just leave clearance in back and front. Google manual and it will tell you

The lamp will not fix the green spots. That is due to bad polarizers in the optic block. The lamp is only a white light.

According to the manual you are not getting enough airflow which would explain the optic block failure. Make sure the TV has lots of space for air around it and is not inside a cabinet that would overheat it.

Turns off during game and the power light flashs red? i have cleared up space in my saved data (didnt help) what do i do?

It sounds like your PS3 is overheating. When a system gets dangerously hot, it will automatically shut off to prevent any damage to the internal components. To prevent overheating, make sure the PS3 is in a place where it gets plenty of air. It's not good to keep it in a cabinet or any enclosed space. Other than that, I would recommend taking a can of compressed air and getting all of the dust out of the system. Make sure all of the vents are clear to allow air into the system. Hope this helps!

Hey,my ps3 will turn on load up nd every fing normal but wont stay on no longer than 10mins it turns its self off nd the red light just flashes.

It sounds like it might be a overheating issue. Be sure the PS3 is in a well-ventilated area. That means that there is plenty of air flowing around the unit. Be sure if you have it in an enclosed cabinet, air from outside the cabinet come come in and air inside the cabinet to flow out, or else all you will be doing is recirculating warm air, which will in turn get hotter and hotter. Try having a little desk fan blowing on the unit as well and see if that will help.

Good luck.

Input signals Marantz SR4003

There are four digital connectors on the back of the unit: 2 optical and 2 coaxial. They are marked a s 1 2 3 4. 1 and 2 are optical, 3 and 4 - coaxial. Also you have front optical connector marked as F.
You can connect 5 digital sources to your receiver. For example, connect your DVD to input 2 (optical) by optical cable and connect your DSS to input 3 by coaxial cable. Assign DVD to digital 2 and DSS to digital 3 in input setup menu.

Wireless headphone connection to multiple components?

Cat,    Splitting an optical output is not recommended.  In fact it would require an optical patch bay, which would be overkill. You could use the headphone output on the front of the Denon AVR3805.    Because this output is behind a door it might be a cleaner looking set up to use the optical output on the top left looking at the back of the unit.  Because those two optical outputs are labeled "optical 3 and 4" they are zone outputs, they should work without having to "map" or patch them internally. The outputs here will be controlled independently as zones from the receiver's remote.      The easiest option looks to be the analog "pre output" located in the middle of the back of the receiver.  The left-most two rca jacks you want to use are labeled "front" and are white over red.  This output will work fine.  Control of the volume will be from the headphone unit and not the receiver.

You can try to move it to a wider place, if its in a close space place, try moving it where it has plenty of room. Do not have it in a cabinet or corner of of room.

I know and places that sells Xbox Accessories offer "360 Fans" that will blow cool air into the console. You may want to try one of those.
