Sony pcg-4f6p laptop lcd screen

What happened to Windows 7 Support?
Downgrade to Windows XP until everything is ready to re install.
One of the joys of owning a Windows computer... Get used to it.

Can you upgrade to Windows 8?
Perhaps your Sony PC is just getting too Old.
Good Luck

that LCD not mach for ur laptop . give LCD part nomber pls

This is most likely an LCD screen fault. You could check the LVDS cable that connects the motherboard to the screen also.

In my opinion it sounds like the onboard video chipset has failed. That would explain why neither LCD nor outside monitor are showing any output. This is especially likely if you are not even getting the initial logo or Power on Self Test showing on the screens when you first turn on the laptop.

Hello
These symptoms are not the inverter problem, What can you do if the laptop LCD screen turned completely white? From my experience I can tell that this problem may be related to the following: 1. Loose connection between the video cable and the LCD screen. 2. Defective LCD screen. 3. Defective motherboard (I assume the graphics card is integrated into the motherboard).
Check these by yourself or get assistance from sony support.
Good Luck

1. It smees your LCD is faulty.
2. connect your laptop to a external monitor. Check if lines are visible or not.
3. if no line are visible then need to change your LCD.
4. for changing better to contact service centre.
5. you can look for used LCD, which will be cheap.

You could have a video controller problem or a LCD screen problem, what you are seeing is the backlighting but no video information.
To check if you have a video problem, connect an external monitor to your laptop and bootup your laptop, if you see Windows booting up the external monitor then the video controller is OK, and your problem is the LCD screen or the video cable connection on the motherboard (may need reseating).
If you cannot fix the LCD screen then use your laptop with an external monitor.

I need sound driver and Modem driver for my SONY VAIO Model Number PCG-4f6p
