My thunderbolt display began being very dim. I have two which I use side-by-side, so the difference is obvious.

Is this a LCD panel issue or more likely in the electronics?

I have looked at the iFixit teardown and it seems like a reasonable repair if I can identify the part.

A dim display is often a failed LED light bar, or either the driver logic or the cable connector.
