Where is the ground to the M2 hooked up? Chassis?
thanks for the reply's but i just connected the screen on the m2 and it was still the same
i used power from a connector to put in a harddisk or dvd player
i dont have any idea whats the prob, because when i power the computer on a battery thats not connected to the whole system , i mean the audio/car ignition / etc
then i dont see any stripes, nothing its perfect even when my engine is started
so i think maybe it something has to do with the m2 or the fans could that be possible ?
i hope its a bit clear how i try to explain it
Are u hooking up both the ground/power of the screen to the M2 or just the power?
Where is the M2 ground connected to?
the ground was made on the frame of the car ,
now i made the ground of the m2 to the battery itself
and the ground of the screen is on the m2
it has improved indeed but the stripes are still there
i will try to put a filter between it or something hopefully is gone then
thanks for the help again
Also check if you have anything with sever radio or magnetic interference near the screen. Sometimes just the frame of the vehicle can bring magnetic interference to the screen.
i think thats not it kalenth but thanks for thinking with me
i think i have to live with this
strange is because when i put the PC on a external battery not connected to the car
its good no stripes nothing
when i connect it to the car, even when its off the car itself i mean
but well i have a light skin and almost dont see them anymore
only minor is that when i wathc a movie its not really nice with those white stripes in the black background
ahh well i will keep u guys posted if i make a discovery what could help
thanks all for helping
The key to the solution is: power from the car = stripes. Power from house current = no stripes.
You have a power supply issue. Do any power wires run near the VGA cable for the screen?
Try one of those ferrite chokes on the power cable if you don't have one already.
well the strange thing is , when i only feed the computer with a external battery there are no stripes, but the screen is on the car battery
so is it still a power problem ?
and there is no power cable running next to the vga cable
also allready a ferrite choke on the cable but that also didnt gave any result
first battery is grounded on the usual place thats the factory battery, the second battery is grounded in the back on the chassis
not on the same place but ofcourse on the same ground if thats what u mean ?
