Its not a camera its a electronic dictionary

Just buy a new one.

This LCD screen has been hit by a hard object, that is why there is a black spot. You need the screen to be replaced, a digital camera repairer can fix the camera for you.

That large purple spot is telling you that you bought a TV with a defective light engine. The problem will just get worse.

Unfortunately, the spots on the screen are either due to the product being exposed to excessive heat, or due to pressure being applied to the screen (someone poking the screen hard with their finger, or stepping on the product.) Due to the low cost of the unit, it's likely that replacing the product with a new one would be cheaper than having the screen replaced.

If it is on all input source. the panel is damaged. You need to replace the panel.

One source for the part is here.

you should replace the lcd screen from an authorized service center. or you can buy the lcd screen alone from ebay and find someone to replace it .remember
never open the camera unless you know very well how to replace it.thanks for using fixya. please dont forget to rate my solution

I think your lens are dirty. Buy lens cleaner from your nearest electronic store. Or do what I do, breath a mist on the lens and rub with a clean cloth. It always does a trick. Don't use glass cleaners.

Hello Mari,
The products standard guarranty doesn't cover cracked screens. You have to replace it. Otherwise the black spot will grow and cover all the screen.
You can find a replacement screen for Casio Exilim Z80 in this link:

It is not difficult to install. Just make sure that the battery is removed and the flash capacitor discharged before opening the screen.

i cant suggest that you attempt to fix it yourself, is it possible the lcd screen is damaged? take it to a local camera or electronics shop and price check repair costs, you could also check ebay for a do-it-yourself repair setup.
