I might be interested, depending on whether I can fix this one...given that 540c panels aren't getting any easier to find, if I can fix this panel and keep one more in circulation that'll make me a happy chappy.

Anyway, its definitely the panel...I pulled the panel apart this morning...if I press on one of the connections on the controller board I can actually make the display come good...I'm wondering if perhaps putting a shim of some kind in there might do the trick.
