Re: pcg-xg28 no display
Either the video card is bad, or the memory is bad. Replace the memory first to see if that fixes the problem. Also, if capable, reseat the CPU, which is located beneath the Keyboard.

Boot into safe mode ...not sure what windows version you have but Google boot with safe mode with windows version windows 10, 7 XP etc
You should see the bios before windows loads. If it turns black when windows is loading bad DIsplay settings or driver.
Hook a spare monitor to the video output of the laptop, if picture okay! the LCD panel display is defective and most be replaced. But if symptom is the same on both screens it indicates a bad Video Graphic Card normally built into the motherboard.
As you tried connect the notebook to a external display and it didn't work. The best option is to get the unit serviced. Either you may contact your favorite technician or you can contact the Sony service center at:
Your resolution is set above what the monitor supports.
when computer is first starting up hit f8 to get to boot modes.
choose Enable VGA Mode: This option starts Windows in 640 x 480 mode by using
the current video driver (not Vga.sys). This mode is useful if the
display is configured for a setting that the monitor cannot display.
When you are booted into windows you can then set your resolution to the highest that the monitor supports which is 1440x900
hook the laptop back up to the external monitor, once it boots and has settled, I would like you to hold down the Fn key which should be at the lower left of the keyboard and tap the F7 key. This will toggle the video output from external to internal or both at the same time. I have never heard of an issue where Ubuntu will allow a video signal, but now windows. I hope this works for you.
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.
try right click desktop go to properties/display setting check that display is set properly go to advanced settings check out there if everything OK go to control panel/device drivers uninstall video drivers reboot it should boot with standard vga drivers check if display is OK then try loading your proper video drivers
Turn your computer on.
When the boot screen cahnges to black start pressing F8
You should get a Windows startup screen
If you see the Windows Logo loading page, then hit the reset button and tray again.
On the Windows Start page, select Safe mode.
Press enter twice and Windows will load
Go into display properties (right click on the desktop and you will see it on the menu)
A box will pop up, select the last tab (Display Properties) there will be a slider on the left side. Move it left to around 800x600.
Select apply and then close the window.
Restart Windows normally and it should be fine.
If not, post back and we will try something else.
Hope it helps =)
