The power light still come son and will even put the computer to sleep. Must be just a blown backlight. I'm going to take it in to get it checked out, but anyone know approx what the repair cost might be for a back light replacement?
thanks

If you shine a bright light at the display while it's on, do you see a dim image?

If no, then the panel or other component (e.g signal processor) has died.

If yes: did all the backlighting go out at once, or did it first drop to 1/2 brightness?

If it went out all at once, then the inverter has gone. If it went in two steps, then the backlight tubes have failed, one after the other. (It is highly unlikely that both tubes would fail at the exact same time.)

Thanks Tooki, I'll check that out (need to hook it back up)

Well I should add the following having done many of these repairs.

the 1/2 brightness question is because you have 2 bulbs one on the top one on the bottom. both bulbs don't die at the same time normally

the inverter dies you see something when you hold a light behind or infront of the panel.

Yup. I said all of that in my response.

When my cinema display died a few years back (rev 1 dvi ) the picture came back when I unplugged the usb. been using it ever since without the usb. looked into getting it fixed but didn't have the money and haven't gotten back aroud to it.
