Screen says " mode not authorised "e turned off at switched and just cannot get anything else on screen

What model Cobra camera? What type and size memory card?

Sounds like you accidentally pressed the DISP (Display) button on the back of your camera. This manually turns the screen on and off in picture taking mode to save battery power. You could then use the optical viewfinder in its place. To turn it back on, just the DISP button one more time.

By giving to an authorised service center.

so your phone is booting...you have to take it to an authorised service center for nokia.. i think its a sofware issue..

I have a sony cybershot DSC-S650, the LCD was very dark and could not see anything except if I pointed it at a bright object, everything else worked ok. I could take pictures but could barely see them in playback as well.

I took it to Sony authorised repair outlet and was told the CCD was damaged, they charged me USD $55 to repair it (in Quito, Ecuador)

Turn the camera on and press the DISP button on the back of the camera. This button manually turns the screen on or off to save batteries.

plug in the mp3 player, once it turns on, hold the power button until it turns off then switch the hold switch to hold (showing orange) and then hold the REC button on the side until the player turns on with a black screen, saying its in recovery mode.

are you able to see the icons on the lcd screen ( you can check it with pressing display button)

If yes, then
There may be the shutter was not opening. So you need to contact Canon authorised service center.

OR
