Hi, My Sony viao is turning on, I can hear the fan and all the LEDs come on etc however the screen is black and does not display startup or anything. After about half an hour or more of turning it on and off it can turn on and display properly but obviously this is not ideal. Anyone have any ideas on how I can fix this?
1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.
NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.
If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.
If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.
