It is a know issue with the Samsung TV that the VAIO laptops does not connect. I request you to perform the steps mentioned below and check if the issue is resolved.

Note: Please read the download and install instructions before installing.

First install the BIOS Update, second install the Sony Utilities DLL Update, third install the Sony VAIO Event Service Update.

All the best!!!

Those 2 software packages offered by Sony on their web site, (a) ArcSoft Magic-i Visual Effects, and
(b) WebCam Companion Software, may just include the driver necessary to get their packages to
work with Win7 - pick one an install it - if the camera works, you got the driver. If the camera still
refuses to work, then all you have to do is de-install the package, install the other one and
give that a try.

The Sony drivers support page (for the Vaio VGN-FZ4000):

I would suspect that the CD-Rom drive has gone bad. The easiest way to check this is to swap it out with a working CD-Rom drive. If the bios recognizes that one you have the culprit. If that is not the problem, I would then check the cables. If they are all ok, I would make sure the BIOS is updated. If none of these solved your problem, It may be a bad IDE or SATA port, or failing power supply.

you can go in bios with F2 this is valid for all or if you cant press Del. but be advised that if you do not know what to do you may unset something that you need.

It is not easy to unlock Sony Vaio Laptops Bios Passwords.
I was searching and i found this
http://www.spunlock.com

They have remote unlock for sony vaio laptops and have been recomended.

Regards,

Start by downloading the latest BIOS update file from SONY here: http://esupport.sony.com/US/perl/swu-list.pl?mdl=PCGFRV25&LOC=3

Then read the instruction they give and follow them.

Good Luck
