Cracked screen I had my digital camera was in my back pocket and I sat on it, is it possible to fix it or should I by another one.

No way anyone can say what is defect. Not even sure the defect was induced while you cracked the screen and became worse during the "repair" or you did make an little error while putting things together. Even in my professional career as a repair engineer, Trying to find an error after a college could not get it fixed complete, were the most difficult jobs.
My best hint for this? start saving for a new camera. Will save you a lot of greef and a lot of time.

You most likely have cracked the LCD of the screen and will need to replace it.

those lcd screens are made of very thin glas that is very easily broken and cracked, once this happens, you need to have the lcd completely replaced.

Yes, the display may estimate up the cost of a new set and so it must be considered if the main board is also cracked.
If so there is nothing worth doing.

My touch screen didn't last being in my pocket, the LCD is fine but the touch screen layer over it was cracked in multiple places. I've returned it to samsung but I'm not sure whether they will cover it under warranty. For a pocket camera not survive being in your pocket is pretty poor. Would definitely not recommend buying one to anyone.

The LCD screen needs to be replaced by an authorized repair service.

the acess code comes on anbd then it asks for me to turn the camera on and off

it still takes photos and i can download my pictures onto the computer and the come out perfectly, it's just that i can not view the pictures on the screen properly!
where do i take it to get fixed?
I live in Adelaide, South Australia

I don't know the replacement cost, but I can bet it is nearly the cost of your camera. You might be better to find one on ebay that has a good LCD and transplant it. It may be a little difficult, but not impossible.

There is a display button on most cameras that you can turn the LCD on and off to conserve battery. Some people like to use the viewfinder so this option is put into some cameras. If the display button is pressed before you turn it off it may save the "last known settings" so every time its turned on and off its still in that state. Look for a menu button or a display button see if you can get it to come back up. Some have a tv out, you could try and plug it into a tv to use as a monitor if it wont come back up. It could be cracked from an impact or the illumination light could be bad. Cracked LCDs are fairly common so thats possible.
