Before buying a new camera because yours has a broken LCD screen, just give it a chance and try to make it work!
The process is simple, and you only need a screwdriver and the replacement screen!
You can find replacement screens on eBay, just look for "Your brand/model name" and "LCD", and of course, try to buy from high-reputation sellers! I took the LCD Screen from eBay into my own in about 10 minutes from start to end, and it should be similar for most digital cameras.
BE VERY CAREFUL WITH THE CABLES! They are very thin and fragile, it is better to be gentle with them
Remember to check where the screws should go, they usually have different sizes.
