    Hey guys - trying to get two CF28, 800Mhz off my shelf. To preface this I have confirmed that the LCD panels are working (tested on another unit). I cannot get either of these two units to power up a known working LCD panel. I have triple checked the two connectors and they are correctly plugged in. My question is first what are your thoughts and two does this sound like a mother board issue? and is it fixable (I hope). Any help or thoughts would be greatly appreciated - Just to clarify I get ZERO display - Thanks

    Wow - found the thread you spoke about - guess not a new problem (just for me I guess) I am off to fix my fuse - thanks a ton.

    I did not have the power unplugged when messing with monitors - cant believe I have gone this long without doing this before - lesson learned hard way -

    Thanks again

    Thanks ohlip - all fixed - was the F4 fuse, once I found the little bugger and got back up to speed on my soldering skills they are both fixed - thanks for the info as always - it is greatly appreciated.

    Lesson #352 learned - must also remove battery and unplug before swapping LCD -
