I kinda disagree with the real need for regulated 12V because:
- in my hami 8", the ccfl inverter gets 4 wires from the motherboard and not just gournd and +12V
- when engine is off and engine is on, no apparent change in brightness is perceptible on the screen; so I suppose the CCFL inverter does not provide a boosted voltage to the CCFL
Anyone could proove me wrong ?
