When you switch on, you should immediately get the 'Power On' light showing steadily. Then you should get the BIOS screen, and while that is still showing, the HDD light should start to flicker / show fairly steadily, and then the computer should boot. This is the normal sequence.
If you are getting the power on light - OK. If you are not, check that it has a battery installed and that the charger is working. You don't need the battery if the charger is working and plugged in. The voltage should be about 18 to 20 volts DC if you are just putting a meter across the outer and inner conductors.
Next, you should get the BIOS screen - in your case it should show some variant of the Sony logo. Are you getting to see this, no matter how briefly ? If you can see this, your screen is OK. Can you see the BIOS screen ? Get back to us

I was afraid you were going to say something like that ! There are a considerable number of possibilities that could be causing this failure, but I can only think of two that can be easily checked by almost anyone - either your hard drive has moved out of position or your RAM chips have.
If you switch your computer off and turn it over, you will see two rectangular covers which are held in by screws. One covers the hard drive and the other the RAM chips. If you use a small cross-head screwdriver, you can remove these covers to access the HDD and the RAM chips. From memory - it's a while since I last worked on a Vaio - the hard drive is retained by another screw. If this is in place, the HDD should be OK. If the screw isn't there, or is loose, check that the HDD is a snug fit in its location and tighten up the screw, gently. The same goes for the RAM chips - make sure that they are a snug fit in their socket. Replace both covers and try booting the computer again. If this works, super. If it doesn't, you are going to need hands on help from someone. I don't suppose you live anywhere near Edinburgh in Scotland, do you ?
The problem is, that from the description you give of the failure condition, the fault could lie anywhere in the system up to and including a dead screen. If the two checks above don't solve it there isn't too much that can be done, as it were, by remote control. If worst comes to the worst, and it is decided that this computer is beyond economic repair, assuming the problem isn't a dead hard drive, you will still be able to recover any data off the drive by slaving it to another computer.
Best of luck,
