    HP EliteDisplay E221 Troubleshooting Help

    I've had good luck repairing the older CCFL-lit monitors and just picked up my first LED-backlit unit--an HP EliteDisplay E221. It powers on, green power LED stays lit, no picture from external source of system menus. I've visually examined for bad caps and, though there are a lot of no-name caps there, none of them exhibit signs of being bad.

    Has anyone gotten their feet wet with LED-backlit units yet?

    It's the same stuff as a CCFL-lit LCD monitor, but with an LED backlight (and respective drivers) vs. CCFLs and inverter circuit.
    Post some pictures of the boards, so we can see what you are seeing.
