I have a shaw gateway and just purchased a yamaha rxv667 home theatre system. I'm having ocasional issues with the volume when i'm watching rgular tv or pvr shows,the volume on the amp will shoot up a

Can you use a different output on your shaw?

Like for example try component video and optical audio cables instead of HDMI, or vice versa.

Or call shaw, tell them their product is garbage and you will quit shaw if they don't send you a new one free and give you 3 months discount price. (I'm serious, do it)

Connecting Kindle Fire to Denon receiver

Assuming that you've tried a different HDMI cable, tried a different input plug and you weren't watching a 1920's silent film..its possible that the front middle speaker is the issue? try and see if there is sound coming from that speaker, its usually where the voices from movies comes from.

My 22 lcd gives good picture but no sound.I've tried connecting an externel head phone but i don't hear any sound.

you're best bet is, depending on your TV's input/output, is to run your video components directly to TV via HDMI, component, etc., of course component requires additional sound cables, then run your sound out from TV via, best, digital optical, to reciever. You use the TV's menu to choose what you watch and, only have the one audio out. Scan your recievers menu to make sure you've got the right channel to listen to.

I have a KLH 700watt home theater reciever that wont stay on!!

Sounds like it is overheating. Try one or all of the following:

Remove anything that may be stored on top of it. Unblock the vents.

Connect speakers with a higher sensitivity rating.

Move it to an area where it has more airflow around it, ie; not in a closet or cabinet.

Disable any bass-boost and equalization, or tone controls.

Set any crossover settings for any subwoofer you may have connected, to a higher frequency.

Decrease your listening volume.

Sony DE-445 reciever flashes PROTECT

Sounds like a grounding problem. If the ground plug isn't missing or loose try plugging it into a different outlet.

No sound driver

Turn the power off. Wait about 10 seconds,then power up again get close to the reciever and listen for a click-not from the speakers ,fromthe recievers itself.If you hear a click,you can assume that the power supply is ok for that cercuit.This does'nt eliminate the power supply,but it will do for now.Put the speakers close to the reciever,what you will do now is to power up the reciever while listening to the speakers with the volume off.In about 3-5 seconds you should a hear a slight click from the speakers. Try this with both speakers if you don't plug in a pair of headphones to the headphone jack and play the source . If you still no sound with headphones you at least now know that the output transistors are not the problem or the only problem.The power amp., section are defected also.Message whatever happens.

HK 3480 sound suddenly cuts out

your fuses are blown by possible crossing speaker wire - and + together. I did this and kept turning it on but I ended up frying the unit. Check your wires and make sure that they are seperated properly. If problem continues then unscrew the shell and replace 1 or all 3 fuses (depending on what was blown) with GMA 8 amp fuses. good luck.

Center speaker

mine is doing the same thing, you can hear a click sound and the channel will die. I think it is a relay or a shunt that trips when something goes wrong with that amp. I dont think it is worth repairing as there are some nice receivers out there for cheap. Maybe just a cold solder joint somewhere? Anyone know where and Ill dive in and resolder and post the results.
