You can not fix a cracked screen. Replacement only.

or bad inverter

You didn't mention what make and model you have - but this seems to be a graphics card issue. Many (HP laptops a few years ago in particular) developed "Cold" solder joints on the motherboard at the graphics card. When the computer heats up, the connection is lost, when it cools back down, the connection resumes. Usually requires a professional repair - either by attempting to "reflow" the solder, or replacing the motherboard in its entirety. Might be more cost effective to consider replacing the computer.

Huh? D-Sub is a connector? If you plug an external monitor into it the laptop is probably designed to shut of the internal screen. If this is not what you mean please get someone who can write a functional English sentence to clarify your meaning.

This appears to be a malfunction in the screen, possibly a crack. The simplest things could cause it (i.e. metal hitting it)

Display is broken. Replace.

some parts inside your tv is damage or short circuited. too expensive to fix or replace

That is normally caused by a bad developer housing.

Sorry to hear about the accident with your cell phone...
If the phone's buttons and keys work fine, you can visit http://www.cnn.cn and order a new screen as a replacement and see if that helps.
To replace the screen, all you have to take off is that front metal faceplate 4 screws under the rubber stoppers and pop it off gently with a plastic tool, then peel the old glass, being careful to keep it clean, snap the faceplate back on so you can align the new glass and stick the new glass in.
Another option is to take the phone to you cell phone provider and see if they can fix it for you. Obviously this is more costly. If you have insurance, they can give you a refurbished phone.
I hope this helps. Unfortunately cell phone damage is not an easy decision on fixing the problem.
