Re: No Sound

O1 is the OPTICAL input. C1 is the COAX input. Try pressing the DIGITAL INPUT button to cycle to the analog mode.

Shut up stereo protect mode?

Protect mode is on because something in your speaker wiring is wrong, or you have a broken speaker, or it\'s too late and you already fried one or more of the amp\'s output transistors.

You gotta fix the problem. Not remove the safety guard and carry on with a busted machine.

Look for wires touching between the speaker terminals or on the backs of the speakers. If you done a half-ass job of wiring up then this is the most likely cause.

If you can\'t find bad/frayed wiring, then disconnect all the speakers out the back of the amp. Switch the amp on. Does it trip out? If no, that\'s good. Turn up the volume. Is it still okay? If yes, that\'s good. You haven\'t yet killed the output transistors. If it goes in to protect though, ut oh. It\'s Repair Shop Time.

If the amp is okay, then power off and add one speaker. Power on with the volume down. If it trips either at no volume or when you increase the sound, then you got a bad speaker and you just found it. Repeat the process, adding one speaker at a time. Make sure you put Vol to minimum and power off each time before adding the next speaker.

I have a RD-6108 5.1 Channels receiver that want to connect to my flat tv. Can you help me?

If you consider that a TV is just a lightshow, it's not that complicated...

Composite Video Out to composite video IN on the TV would be the minimalist absolute necessary connection for managing the receiver through On Screen Displays.

Unless you intend to dub video to a VCR or something, there is no reason to bring TV video into the receiver.

My preference is to send the BEST version of any medium (audio or video) directly from it's original source to the BEST ELECTRONICS that uses it; then send minimalist versions across for convenience and lo-fi watching/listening.

Any self-respecting modern TV has multiple hi-def video inputs, so run the Bluray, DVD, cable box video straight in and run the audio from those devices to the Sherwood.

Fewer expensive cables, no excessive connections to go bad, no unnecessary handling of the material.

I'm pleased to see the manual for this one (and the product's limited video capabilities) don't tempt the user to route everything through it on the way to the TV.

How do I reset the defaults on my Sherwood RD-8108 AV receiver?

I just got a tip from Sherwood tech support on resetting my Sherwood receiver, and it solved my problem perfectly. It's not the same model number but here's what I did: Put the receiver on Standby. Press and hold the Setup button for 3 seconds. When you see the model # on the display, press Enter. The word "Cleared" should show on the display. Hope it works for you also.

My Sherwood RD-6105 shuts off if I turn it up past 28 or 29 db (which isn't very loud). I'm using it in Dolby Digital mode. It even happens when I use it with my components that are analog. This just...

It's acting as if a short or near-short exists on the amp outputs at medium levels.

Disconnect one of your speakers at a time and try it. Make sure your speaker wires are tight and not shorting to anything and all channels have 6-ohms or more load.

I am wanting to start using optical but the channel (01) keeps flashing and theres no sound? Any Ideas?

CD 01 coaxial digital or optical inputs. If the 'o1' is flashing this means there is no signal. This could either be a damaged optical spdif/ coax cable or the sample rate your sending to the sherwood is too high (over 96k ?) lastly it would be a fault with the system itself.

LG 55LH90 TV to Sherwood RD6500 receiver

That's what manuals are for.

Video Out on the receiver goes to Video In on the TV. That's all you really need.

I recmmend you grab any TV-related audio from wherever its source is for the highest fidelity sound (NOT the TV).

Hear sound but cant get any real volume even at full blast

I was playing around with my Sherwood RD 6513 and adjust the the output level to its maximum, amongst other settings. This limited my output on the amp to a maximum volume of 65 not 90+.. Anyway i pluged in the microphone and done another 'auto setup' of the volume levels and distances, and this allowed the volume to exceed 65 again!

Also if you have an external source such as a DVD player - i would assume you have already checked its output volume setting?
