    yeah it is cool. i am damn jealous.

    On another side note: It is amazing the difference Xenarc made between your old screen and the later ones. The onboard inverter is very crude and will have to be disabled when people upgrade by cutting the tracks - like on the lilliput. The panel is slightly different but i suspect the difference is just the moving of a small board on the LCD as the CCFL seems the same. As far as i can see the $150 Xenarc upgrade is a new controller with the separate inverter (or simply putting a new inverter in and killing the original).

    The newer xenarcs seem to have actually redesigned the board from the ground up

    I need to compare the datasheets on the two version to see if they changed the output of the ccfl or they just pumping more energy into it

    but after taking the xenarc LCD apart, I have high hopes that we will be able to get the tubes to fit into there as well.

    oh god yeah the boards are worlds apart.

    The Gain modules that digitalww sells are similar to the latest xenarc but not the same.

    The newer one uses a lot more surface mount stuff and amkes the old one look like it is out of an 80's TV set.

    Oh, i noticed from a screenshot in an ebay auction for the old blue button model that it has autodetect in the OSD so maybe the old ones did have autoswitching - unless it is something to do with auto-on or the resolution.

    well depending on how much current you run through it, could be cutting the life in half, could be cutting the life down to a couple months, untill I can find the datasheet for the hitachi panel, I wont know

    wont work, I already have a inverter like that and it's garbage

    We cannot go without the dimming, because just using my upgraded one is unbearable at night
