    LCD flicker, help!!!!

    My motorised Lilli flickers.

    I've tried everything on suggested on the forum but nothing works. I can't power if off the PSU because it uses too much power.

    Its because of the harddrive, i think when the drive is accessing, its sending ripples though the VGA cable up to the screen. Any electronic experts care to share some knowledge?

    I found that updating the drivers on a friends PC solved his problems.

    Just make sure that you have a very solid ground and adequate power going to the screen in the first place.

    i had a similar problem when using my OPUS Dc-DC Supply, it would ripple the video signal and pop the audio, it turned out one of the SMD Capacitor was faulty

    Does it do it when powering the PC with a ATX PSU?

    everything is grounded and connected correctly as far as i know. when the computer is idle the screen does not flicker, but as soon as i access data or run a program flickering occurs (hard drive access) it doesnt do it connected to normal power and i have also tryed a video card in it with no luck!

    Ive read through the forums that connecting the LCD to the computers psu (m2-atx) it solves the problem, but is there another way around this? its driving me crazy

    your power cable to the monitor, does it have a black box on it with a regulator and filter capacitor?

    the reason that connecting the screen to the PSU solves this problem for some is that the PSU provides more regulated power. From what I remember, the Lilli's need that regulated power, while the Xenarcs don't necessarially.

    Thats Correct, thats why they have the Regulator/Filter Box on the DC Line in for the Car Adapter
