If you can replace the screen yourself, it costs the price of the screen. If you have it done by a repair shop you have to pay for their time also. Say it's USD 100 more.
Today my Asuspro suffered a fall and the bottom left of the screen started to fail like so: https://postimg.org/image/bjcjensuf/9dbcfd9e/ When I do a Prtsc it shows as normal so the screen must be destroyed? How can I fix this easily and how much will it take if I take it to a PC technician?
