Question about Computers & Internet
The machine boots up and you can see the "VAIO" image in the back ground but the backlight does not come on. I suspect the LED backlight power supply fuse is blown. Does anyone know where this fuse is located? Much appreciated
If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp.

I have set the password for administrator when i entered the bios set up. you can change its setting but not the configuration unless you've entered the password. you can't change the password with a new one if you cant enter the old password. Next time dont forget your password because laptops has its security even when stolen you cant open its bios set up if its protected by password. CMOS battery is in the mother board. You need a service technician to open your laptop to reset the bios setup battery.

Possible hard disk failure or hard disk controller failure.
if you feel confident remove the hard disk and replace - obviosuly make sure that there is not power running and remove the battery - replace hard disk then battery then power and try again.
Do you get any beeps? is the hard disk clicking? listen carefully to it and post your findings.

I actually did have a problem that was similar the screen would lighten up after a min or so and moving the screen fixed it. The actual cause of the problem was a loose chip on the circuit board of the LCD, i re soldered it to fix it, could also be a bad LCD cable.

The fault could be a faulty CCFL lamp or inverter.
To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
