There is likely a static charge (voltage / difference of potential) between the the receiver and the TV.

They should have their grounds tied together. This should be covered in your owner's manuals.

In some cases, there may also be a stray voltage on the cable line's ground. If grounding the two together doesn't work, you may want to call the cable company (or you or a friend may be able) to check the cable line for a stray voltage or bad ground.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

SOURCE: Yamaha RX-V995 receiver turns on & then powers off 2 seconds late

I suggest you run self diag.  press [FM/AM] key + [Input mode] key and press the [power/standby] switch.

ps prt = power supply problem
dc prt = shorted output or leakly cap in channel
tmp prt means to hot on heatsink

you'll likely have to measure the resistances of the output FETs to find a short,

SOURCE: no picture from wii

The RX-V800 switches the various video signal types separately.
Since you are feeding S-Video to the TV the composite (yellow) input from your Wii is not going anywhere.
If you cant get S-Video output from the Wii then I'd suggest a simple Composite to S-video adaptor plug ($5 say). It worked for me with a Game Cube.
Cheers

Right channel not working on yamaha rx v793 receiver


If the channel is dead on headphones suspect a fault in that channel. The good news is that you have the good channel to compare it with. Since the channel parts are identical. You can start with a visual check. Looking at the good and compare with the bad. Any bad looking parts should be replaced. If you are experienced with electronics you can do tests on the channel. Otherwise it is off to a repair shop with it.

How do I connect my 901 equalizer /speakers to the yamaha rx-v633 receiver?


Sorry, it doesnt look like you can hook up an external EQ while still using the amplifier section of the yamaha. Instead, You would have to use the preamp out to go to 901 EQ, out of the EQ into another stereo amplifier, then to the 901 speakers. Personally, to power the 901's properly, I'd use another external amplifier. You will barley get 75watts per channel out of the receiver to power the 901's

I have an old Yamaha RX-V793. It works perfectly fine. Now I have a new LCD screen, a new DVD player and my new cable tv set top box. All 3 take and use HDMI. I'd like to be able to HEAR BOTH my DVD...


hi,
u can make connections only through digital inputs(optical and coaxial). u can connect the digital outputs of ur dvd and cable set top box to the receiver. no way to connect HDMI. HDMI is a high definition media interface. for using it u have to go for a av receiver that supports HDMI.
ok

Yamaha RX-V793 flashing light on volume control and no volume


Per Yamaha support page: The volume light on my Yamaha AV receiver is flashing, what does this mean ? The "MUTE" function on your remote control has been activated. The reason that you can still hear a very low sound is that the muting circuit within your stereo is not a full mute, but rather a -20dB mute. To deactivate the "MUTE" function, simply press the "MUTE" button on your remote control. (Make sure the volume control is turned down to avoid damage to your system.) If you misplace or lose your remote control, you will have to purchase a new remote control unit, as there is no duplicate function on the front panel of your stereo. Unplugging the stereo will not deactivate the muting circuit, as the microprocessor "remembers" if the muting circuit was active prior to being turned off or unplugged. If you need to purchase a remote control, you may order one directly from our parts office. You may reach them by dialing (714) 522-9888 from 8 am to 3 p.m. Pacific Time, Monday through Friday. If you have any other questions, please contact our customer service department by dialing (800) 292-2982 Monday through Friday from 8:00 a.m. to 4:00 p.m.
