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.

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,

go to best buy and buy a new recever

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.
