Do you have another monitor to test with? I just use regular monitors on mine.

Yes, but I've got slightly the wrong VGA-DVI adapter, and the "spare" monitor ( actually the wife's, but she's overseas) has four extra pins that the adapter doesn't have the right sockets for. I keep thinking that I had one that worked, but I think that's just wishful thinking. A trip up to the shops ( in this case the local Apple Store) will be needed.

Thanks for the suggestion :).

Alex.

The green power LED on the board is lighting up, and there is power through at least some of the circuits as the USB CD/DVDD drive hooked up to one of the board's USB ports, that has my Ubuntu 10.04/LinuxCNC 2.5(?) disc in it, powers up fine when I turn on the little Pico150 PSU.
The green light comes on whether the board is powered up or not. The board won't turn on when powere is first applied, you need to also make the switch-on circuit. This is two pins on a 9-pin header which is for power-up, reset, Power-On LED and HDD LED.
The boards come with a big sticker showing the location of this header (and the other ports) but you might not have that.
I'll pull the memory out next but I've a feeling that something on the MB has cooked - maybe a stray touch from the fingers even, despite my care and the anti-static strap that I purposely dug out for the occasion (and clipped onto a sturdy metal object).
I have taken less than no care with mine (which spent several weeks sat on a nylon carpet) and it is fine, so I doubt youhave killed yours.
Another answer might be the low-voltage monitor that I'm using: it runs off a 12V switch-mode wall wart (like the Mini-Box Pico) and the board isn't the LVDS version....
LVDS is an alternative connector to VGA, and an alternative (digital) image-sending protocol. You physically can't plug an LVDS monitor into a VGA port.

Aha! Thanks. I'd given the sticker - which I do have, and a whacking great poster - a hurried look earlier but overlooked that header thinking that it was a duplicate USB header, rather than actually reading what it said :rolleyes:. Of course. Stupid me, I should have worked that one out for myself :blush:.

The whacking great poster is even more explicit with instructive and useful icons, oh deary, deary me. *sigh*. It's all really easily sorted...

Thanks for the object-lesson!

Alex.

It might make you feel better to ponder why I guessed that as a possible solution so quickly :-)

Since you aren't using a computer case, you need to set up the power-up button. I doubt your motherboard is turned on. A led may be on, but the motherboard is power-off so it will not show on the monitor.

Yes indeed!

I spent a few happy minuets gutting the old PC tower for parts, netting the ATX switch, a reset button, speaker, a couple of rectangular LEDs, and a chassis plate which I might use. In fact, I could have simply removed the PUS and used the old computer box, thereby saving $$$... Still, I've got a case in case I decide to build (yet) another PC. Now to test out this "new" component and hopefully fire up (but not set fire to) the new MB :).

Cheers,
Alex.
