Lcd grounding issue, can't get rid of flickering
I'm having serious trouble with flickering on my Gain 7" TSV LCD monitor.
I tried figuring out the problem last weekend but wasn't able to to get rid of it. I've been reading alot about similar problems on the forum now and gonna try doing some more modifications.
I know have the lcd powered from the battery, it flickers but the ground of the lcd is grounded to the cig light in the front. I'm gonna try feeding it from the opus and grounding it back to the opus in my trunk.
I've also bought a ground loop isolator, since this is what Opus recommanded, but the isolator is supposed for use on a rca audio cable. How can I use this on my lcd problem?
Also I have two amps with together 1000w RMS. After I've installed the Opus the lcd is fading in and out with bass like crazy, sometimes the lcd even turns off, allthrought my lcd is powered separately directly from the battery) I never had this problem before I installed the Opus! ( I used a laptop before)
I can't imagine the 120w opus could make such a power difference for my lcd.
Hope this will dissapear when I power it of the opus.
It must be the lcd ground that's causing the flickering. Last week I tried these methods withouth moving the lcd ground, none was flicker free solutions:
direct from battery
throught gain 12v regulator
throught more expensive 12v dc-dc regulator
but if the the carputer itself runs off an inverter and the lcd from the car battery then no flickering.
