Does your laptop screen go pink when you turn on your laptop, or do you have heard some beeps without any pictures  appearing when your laptop starts up ? Now I will talk someting about this pronblem.

If your laptop screen gose pink while the picture can still be seen when the laptop is turned on. The probably reason is that your operating system is bad.  What you need to do is formating the hard drive as there may be virus on your laptop.

If your laptop screen gose pink without any pictures and there are beeps when you turn on your laptop. There may be the problem of backlight inside the LCD screen. You can test it with an external monitor. If the external monitor has pictures on the screen, the backlight lamp on your own laptop screen is bad and you should replace it,  but it is very difficult for you to replace the backlight lamp so you had better repalce the LCD screen.

While if there is no any voice when your laptop starts up, and your operating system and backlight lamp are all right. The motherboard may be bad. You may have to replace it with a new one. Of course, you may ask for help from professionals.

There is no doubt that there are other reasons for this problem, if you have different opinion about it, PLEASE leave a comment and let me know.
