Sony Viao PCG6w3l showing white diaply. pls suggest the solution

A white screen meant the LCD controller was not working - what you saw was the backlight without polarization in front of it. If the cpu fan isn't spinning, that means the system board doesn't detect the right startup conditions. You probably connected the inverter improperly and it may be preventing booting, or you may have damaged a component with static.

reinstall os

Your Viao will NOT "See" these drives as they are NOT formatted so they can be seen by that PC, you will have to Format, them to use them.
If you do NOT wish to loose all information on them, the only way would be to use a suitable HDD and OS, and mount them via a USB to HDD "Dongle" then you would be able to read the data back.
You see the Apple format is NOT compatible with VIAO, at all.
IF you did wish to use those drives again you will have to Format them via USB on another machine then use on the VIAO.

Sony has identified a limited number of VGN-CS series computers which may display a horizontal line on the LCD screen.

this will ensure you have the latest software + drivers for your system.

problems with CD drives tend to be problems with the IDE drivers, so it may be a good idea to download the latest Chipset drivers either directly from sony (or using the tool above)
or downloading from the intel website
