Blank Screen When I turn on my camera the screen remains black with nothing else visible. The power light comes on also. I just put brand new batteries in the camera. When I turn it on it won't turn off, I have to take the batteries out in order to turn it off. All this happens with or without the memory card in it. Please help!!

A blck spot on your pictures, means there is something blocking light on the sensor. Could be dirt, but more lightly is there has formed some mould.
Because you can't open a compact camera to clean the sensor, I think you can't solve this problem. Opening the camera is no option, because without skills, tools and manual, you won't be able to put the camera together. A repair shop most likely won't start the job, because the repair will cost more than a new camera.
Sorry I can't bring a more positive story.

The camera at the rear end is not feeding video back to your screen or the screen is dead.

Take out your ram sticks and put them back in. Also disconnect your hard drive and reconnect it. Then restart. If this doesnt help you may have a blown power supply.

is this a brand new system ? if so, bring it backl and have the correct the issue.. it is under warranty

if its used computer , did you get the CD recovery set ?

Connect it to another monitor,and see if it comes on. Your screen may be damaged.

its a inverter circuit fault.

there is a hole on the back usually goldish inside take a pen push it in there hold for a couple seconds and press the power button

My viewing screen is black. I had successfully taken a picture, viewed it, and turned the camera off. When I turned it back on about 30 seconds later, the viewing sceen was black. I can 'take' a picure, but it comes out black. Help!

I have to say Mac's I know nothing about. But the simple way would be to purchase a universal USB card reader- and use that.

well your screens broken mate the only thing you can do is get a new one
