Sound but no pictures

take the lense cap off

Hello, Sounds like an LVDS Cable or T-con Board.
Usually this will slowly get worse until it is repaired. It is caused by a failing T-con (Control) Board or connecting cable. T-Con Will Need replacement. This picture show's more extreme T-con board failures

Your device has the option buttons on which to select recording by observing the process from the user observation scopes. One option only could be observed at the recording session. On the other hand, disabling the option of observing a recording session on the scope lense automatically displays the recording session on the visible lense LCD screen area.

Manipulating the Camcorder is from the option buttons located along the sides of the camera. A switch on the menu area should make that experiece achievable.

I took it back and got a full refund.

So camera doesn't give live view to take picture? and you can view old / stored  pictures OK, is it?
If yes, then it is problem of CCD imager in Canon A80 and this part needs to be replaced.
Canon will repair your A80 free of cost as per announced scheme of CCD imager support.

i think you are in picture mode when the screen mode is changed then it will appear black and recording cannot be done beeing in that mode you have to change the screen mode into recording mode and then continue

hi
you should have the heads cleaning,
try to put a cleaning tape and run it for playback then try recording again
thx.

hate to suggest the obvious, but did you take of the lense cap?

Hi, I recently had he same problem, you need to have the unit repaired, it is a small but extremely expensive part that has broken. If my recollection serves me right, it's the colour sensor. There are three that combine the colours to give natural colour. My repairer stated that vibration caused the problems to my camera. Good luck.

hi, this usually happens with the ribon cable which is giving power and signal to LCD is becoming loose or damaged due to folding..since the LCD wiring replacemet is a skill needed task i recommend you to give it to the nearest service centre so that your cam will be ready for future shots all the best my friend sreejith
