i purchased this computer in 2013.
I have experienced the following problem.
When I start the computer in a room where its temperature is lower than 70F, the screen is covered by colored horizontal bands. The screen is showing gradually the real information from the top. It takes about 10 to 20 minutes to back normal screen. After this, the computer works fine without any problem.
How can I fix this problem?
How much the cost of the repair?
