The laptop screen flashes accompanied by electrical popping sound when doing things like streaming videos or music. When the dvd is opened it also makes a popping noise. The computer doesn't have any other symptoms than this such as restarting or blue screens.

It will make noises like that plugged or unplugged.
 
You've almost surely got a short. Probably due to a broken or pinched display panel cable or a bad capacitor on the motherboard. If it's a pinched cable to the display, or the cable has worn through and is shorting between "wires", you can probably replace that yourself by googling your model and disassembly videos. Youtube almost always has at least one disassembly tutorial for most models. If it's something on the system board, it's probably either not repairable or beyond what the average person could hope to accomplish.

There is the possibility it's related to the power jack though. Does it do this regardless of whether it's on AC or battery power?
