Yup. This is the laptop I use on my test bench with an external monitor...

Then yea, you should have seen the POST screen at least, unless the backlight isn't coming on. Then it would still look black even if it was trying to display it.

Yea if your backlight is out, sometimes you can still tell if the screen works by, shining a flash light directly onto the front of the screen and you should see a faint outline of something(POST screen or what not). That should tell you if yours screen works but your back light is just burned out. Good luck.
This trick only works if it's an "Always On" screen and not a screen that goes into stand-by or sleep.

I will try that, but on all three? I think that is unlikely.
I used an extension cable for the VGA... I am going to try it with a direct cable today...

Not taking any of this as that and not stating that these are not what you advertised. I only spent a few minutes with them... I will work with them tonight and let you know...

Windows 98 laptop connected to an external monitor. I disconnected the cable from the monitor, connected an extension VGA cable, then into the 10" touch screen VGA port. Powered everything on...

there is probably something simple that we are all missing. the equivalent of an open interlock switch.
are the blue and black wires connected to board f supposed to be hooked up to something?
here is a pdf about the vamp board. (board D) it also explains the 3 switches
It seems like I am not getting power to the backlight, which (I think) is the pink and white wires connected to board F.
on board F there is a on off switch header between the blue/black wires and the yellow/black wires. do we need to hook up a switch or something to that header? it jumped it with my car key and it didn't do anything.
time to go find my multimeter before I pull these out again.

The blue and black wire was a brightness knob, i think if you turned it all the way to your right it would turn the screen off

I sold around 40 of these things has anyone got this up yet??? It kinda blows that you 2 guys cant seem to get these working....The whole purpose of these was to sell them cheap, and throw in a bunch of free shit, and give back to the community of klov. Its got to be something simple...
Tronic it seems you got yours running with no problem
Can you walk us though this?????

this very well could be the problem.
a brightness knob would be a potentiometer, a variable resistor. without that knob there is infinite resistance, which in theory would mean the screen is turned off.
someone want to try shorting the blue black wires together? if not, I'll pull mine back out and try it once the kids are in bed.

I will try it.
It also seems that the VAMP board has a white power connector on it. Mine has nothing plugged into it. Testing now...
Will report soon...
