Probably LCD is the most fragile part of any laptop or other hand-held device. When you drop your device on the corner or bend too much, you will definitely crack the screen. After this your computer becomes unusable. What to do next on this situation? First of all try to evaluate situation and see how old your laptop is. If you planned to upgrade to newer, then it is the right time – you can sell parts of broken laptop on eBay or on local market. Anyway if you have a bit of engineering steam, you should fix it.
Replacing of LCD is easy task, then only problem you may face is finding right LCD for it. Laptop screens are pretty much standard all you need is to find right size and type. If you are not sure, remove broken LCD from broken laptop and look at the sticker on the back. You will find screen model number like LTN154X3-LOD. Then number 154 indicates that screen diagonal size is 15.4-inch. LTN indicates that manufacturer is Samsung. You can find pretty much all codes by googling it.

You don’t always need to look for LCD from same manufacturer. But be sure to check visually if sockets and connectors are same and at same positions. Also an inverter should be same. Don’t forget fixing points – they need to be exact otherwise you wont be able to replace it.
Once you know what to look for you can try different sources. The obvious one is an eBay. Depending on your LCD type and size prices may vary from $50 to $250 dollars. If you don’t want to risk on shipping it – try local dealers for OEM replacements. If you laptop is quite old and LCD doesn’t have to be new, then try to search in classifieds for LCD panels or even laptops with blown motherboards. They usually sell cheap. They are great source for LCD panels.
So you have your LCD – the rest is easy task – removing damaged panel and placing new one. If you need a little help there are many resources and videos on internet with help when you experiencing problems with your laptop screen. But practically all work is to unscrew, open LCD panel, unplug cables and replacing panel. Then connect everything at was before and you can switch laptop on to see if it works.
Always be careful when carrying LCD with your bare hands. A small bend or harder push may crack it. I had such experience – grabbed LCD on a corner with single hand and it cracked. So always two hands and gentle movement.
