Well lads,

Got an HP Pavilion zv5000, the screen seemed to be flicking off, and I could hear some sort of electrical sound coming from the laptop, bit vague I know but anyway.

I replaced the inverter, and it seemed to be working fine for around 30 minutes, now its doing the same thing again. the screen dims, hear a sort of electrical sound then it goes completely.

If I press down the button to turn of the screen when the laptop lid is closed, the screen will pop back on.
