Problem LCD 8'': vga signal just for 2 seconds

Hi everyone

I have this problem with an LCD 8'':

all the leds and connections seem to be ok (I cannot be sure at 100% though), but the VGA signal appears just for a couple of seconds (sometimes not at all, I've to say) and then the screen turns blank.

(I see for about 2 seconds the bios screen, then turns blank, then I see the Windows logo start up for 2 seconds, and blank again; I tried it both in car and at home).

Does anyone have some suggestion...?

Thanks a lot

Typical backlight failure, at least in larger TFT monitors. In every change, the monitor turns backlight off for half a second, and on again, therefore the backlight is working for a second or two.
