    Please Help!! No Input Signal <---

    Hi all gurus,

    i have a 8" lilliput installed in my car and connected to my pc using the supplied VGA cable, i did not dismantle anything as im not good with my technical skills.

    Recently the lcd just kept showing "PC" for a short while then shows "No Input Signal". I cant do anything at all, Menu, Volume,Left,Right got no response at all. i can only power on/off, and scroll through Video1,Video2 and PC.

    I have tried a couple of resolution including 800x600, 640 x 480 with alot of different refresh rate. I also tried connecting the VGA cable to my laptop and "function + screen". Nothing happen.. still "no input signal"...

    I also tried to power on the lcd "after" my pc have booted up in window (i power on after 5mins), still no display...

    Any gurus can advice on this please??

    Many thanks in advance!!

    Make sure the drivers are installed correctly, and also in the display settings, you might have to run the monitor as monitor number 2.

    Did you check ALL the connections for contact error?

    Dear sir, i have taken out all joints and clean them (well, i rub) with my fingers.. and tighten/clip back securely. there seems to be a little electric current when i "clean" the vga connector with my fingers.

    is there any better ways to check for contact error??

    many thanks!

    I have the same lilliput and a few nights ago, it was doing the same thing. I tried rebooting the computer to refresh the signal, but nothing. I tightened all the connections, and rebooted once more. This time it came up. I am not sure if it was coincidence or whether the PC really wasn't sending a signal for some reason...but either way, it works now.

    Dear Sir, are you saying i should reinstall the lilliput driver before i plug the monitor and touchscreen USB into the PC? i tried just to connect the VGA cable alone to the PC. still shows "no input signal"..

    oh after my reinstall of windows xp. i was using a 15" lcd monitor and was working fine, it just didnt work on the lilliput..

    Many thanks!

    OK, give to the LCD a VIDEO signal and switch into AV1. Is it working?

    Rubbing the connection with your finger is not enough and usually make the connection worse, because all the grease from your fingers went to the metal.
    But I do not mean the vga connector. I meant ALL the connection inside, including ribbon cables. To pull out and put in again is enough.
