First clue was the output sound and then the video went

Hi...
OK..I'm kinda confused with this question. How old is your TV ??
I went to the Amazon Web, I looked at Emerson TV..all flat screen, (that seems to be all that is sold these days)...but all the TV's I saw, have various RCA, HDMI, Ethernet, mini-jack, and USB input...some of these are outputs like my audio outputs I use for my Bose system, for the large rich sound coming from the entertainment center. Everything is on the backside unless you are talking about a TV mounted on the wall, and you don't have access to the backside, cause it ain't your TV to be messing with..
Good Luck

With what signal did you try? Maybe your signal source (DVD/TV or radio) didn't contain any sounds for the center channel.
Go to the Setup menu, Speaker setup / Manual setup and find there item called "Test tone". It will output a test tone to each speaker individually (you will see on LCD which speaker is being tested at each moment). If you will hear a sound from the center now, there is no issue and center is working fine, just your source didn't contain any sound for the center.

If it doesn't work, then either you have faulty cable, faulty speaker or faulty center output of the receiver.
- Try connecting the center speaker to different output of receiver (this will test if speaker is OK).
- Try connecting working LEFT speaker to left output with CENTER cable (this will test if cable is OK).
- Try connecting working LEFT speaker with working cable to the CENTER output (this will test the output of receiver if OK - but use the Test Tone from Setup).

A buzzing/humm sound could be a earth loop problem. This is caused by connecting amp equipment into different mains power outlets.
Use a power board and connect all your amps and laptop to the one power board.

The FC Twin connects through an RCA connector, and can be hooked into a surround sound system. When using stereo and surround output from these systems, NES sounds and music may seem very different from their typical mono output. Using output modes that properly generate mono sound, either through a single center speaker or cloned to multiple speakers, the sound output sounds mostly identical to the original NES. The FC Twin does not produce some sounds faithfully, even with mono output; sound effects in the Super Mario Bros. series games will for example immediately seem different. Nevertheless, some later models of the console produce NES sound much more faithfully than units made closer to launch. Recent models produce sound with complete fidelity.

IT COULD BE THE BATTERY BUT I WOULD LOOK TO THE ALTERNATOR TO MAY HAVE WARN BRUSHES

i think you camera,s software is corrupted
go your canon customer center for repair it

Before anything else.... you must examine first if your card is not damage, How? Try to test it in the memory card readers or other camera that fit the same memory cards. 
Some other cards do have lock option in the jacket of the card. Try to unlock it. After doing so reformat the memory card in to your cam.

Other option...... Some other cam do have internal memory, if you have the same, configured it out.

The Black Screen of Death is a common problem with Sony cameras from around 2004-2006. If you have a Sony, it's very likely that the CCD chip in your camera is toast. Good clue to this is if you can play tapes in the camera, which means the tape heads, screen, and much of the electronics are working fine.

You can try calling Sony at 1-866-703-7669, Custormer Information Services Center. They were sending shipping labels to customers with dead CCDs, so the cameras could be sent in for free repairs. This was a year ago - I'm not sure the program is still in effect. If not, they should still be able to tell you what it will take to repair the camera, since they know exactly what the problem is. (You might end up with a refurbished unit, but that's what your camera would become anyhow.)

Your set is shorted circuit condition. The power supply is making the noise. Unfortunately almost any of the hi current circuits will do this. If picture went out 1st look for video or hi voltage problems.
