**vincenttor** · 11-27-2008, 03:57 PM

well im have no degree or something in english and dont have a idea how its called in english
i have installed my carpc and the touchscreen its a lilliput 7"
now i have connected it to the battery got 2 battery's both do the same btw
and it works good the computer starts , gives me an image etc
but i see this very annoying stripes

ive tested many things, no extension cable between the screen and computer, different power sources , nothing else on because i have xenon lights and those give allot of interferance but thats alos not the problem, powered without the amp's head unit etc
still getting those annoying stripes
does anybody has the same problem or has a sollution

thanks allot

Looks like you have a bad ground for the screen. I have seen that before and a bad ground was the issue. Where are you getting the ground/power for the screen?

I would suggest that you get both power/ground from the computer's power supply.

thanks for the tip, i got the screen connected to the battery in the front of the car
and the computer in the back of the car
ill give it a try , also opened the case and post a pic of it here maybe someone can see if something is wrong like a wire against something that isnt supposed to be

Definitely don't connected straight to the battery. Get both the ground/power from the computer's power supply.

thanks fabworks, it sounds also logic what u say
i just tested the carputer on my starter kit
powered on that battery it doesnt give any stripe on the screen with the screen on a different battery btw
tomorrow when im done working i will test it on the power source of the computer self, got also an email from the guy i bought the carpc from
he said also something similar what u said
i will keep u guys posted
thanks again

Are you using a M4 or M2 power supply??

**vincenttor** · 11-28-2008, 11:50 AM

its the m2
here some pictures of my computer
has the m2 not enough to also power the lilliput screen ?

The M4 and M2, in my opinion, are not worth the money...
I had serious issues with a M4 (screen problems like yours AND no sound out of the sound cards)...I tried 2 seperate M4's...same problems.

Bought an OPUS and called it a day

I have been using the M1 and M2 for years without any issues. The M2 can handle the screen easily, I have it hooked up that way with no problems.

No sound for sound card would not be an issue of the power supply.

Yeah, it is! Obviously the M4 couldn't power a pair of Xonar's...
It doesn't supply adaquate power to the PCI bus.
I tried TWO different M4's on TWO different motherboards! Nothing but static out of the sound cards...and corrupt display.

As soon as I hooked up the OPUS, no more issues...yeah, that doesn't sound like a power supply issue to me!

And I didn't even have the screen powered off the M4's...just the bare minimum.

I'm sure lot's of people don't have issues with the mini-box PSU...
But lots of people do have problems as well...

Anyways...
You might try powering the screen off the M2, and make sure the screen and M2 have a common ground point...preferably NOT a chassis ground, but straight from the battery...
