Laptop screen problem

    Lads,

    Gonna run this past you's before I do anything.

    Samsung Q35 laptop - ever since the other day the screen backlight gives out. I turn on the laptop and 99% of the time th backlight is of. I 'Fn & F5' to turn on the backlight but it turns on for about a tenth of a second.

    I can 'Fn & F5' but every second time it flashes on for a tenth of a second - the first time I press it it does nothing (as it the first time I press it turns it off).

    I've wiped the laptop in case it was a virus and updated the BIOS with no joy.

    I'm beginning to think it might be the power supply on the blink. If I plug out the power supply - for the first 10 seconds the screen does the same but then goes to normal where I can use it as normal.

    Before I waste my money buying a new power supply - is there anything else I can try to confirm this or any other suggestions...?

    Thanks in advance.

    ^ He's right - most likely the inverter if its a model with multiple flourescent tubes for backlighting. It can't keep the tubes stable after trying to kick-start them, thus the flash every time you try to turn them back on.

    Is that Q35 still under warranty?

    No its about 3 years old now but such a work horse for me.

    One thing I've noticed is once I start it in battery mode I cannot turn the backlight up to maximum brightness.

    Would this still be related to the inverter..?
