I realise an inverter is not the way to go, but with my monster 400w psu i havent got many options...lol
Anyway, inverter and PC aside as i get the noise whether the inverter is on or off.
RCA's and VGA's disconnected, so it cant be them being too close to the power cables (although they are running down the other side of the car anyway as a matter of caution).
I will look at powering my screen via my PC (as the power is more stable), but as it designed as an in-dash screen and can be used stand alone, so it shouldnt really be a problem.
Something i found very strange earlier...
I was redoing all my cables incase i had nicked one somewhere, connections loose etc, i forgot to reconnect my ground cables when i turned on my screen. My screen came on, which i find odd. So i experemented by touching them to ground and it made no difference what so ever?!?!?
I am still getting a noise (constant whine) when the engine is off and then it raises and lowers with the revs with the engine running...
Should my screen work when not grounded?
Is it getting its gound elsewhere?
Have i got an internal wiring issue?
Cheers
