May I first belatedly (quite belatedly!) apoligize for my "late" response and thank everyone for the really thoughtful (as well as technically well-grounded) suggestions. The DRV issue was my very first post on this forum and, after reading your responses, it consider it a great start! Almost a year-ago now, I put the drive in the closet and went to Saudi Arabia. Returned last week and... same problem, but havent had time to get into it yet. I don't have immediate access to a Linux machine or another LG so I'm going to take it ito a BestBuy and test it on one of their store displays. Not conclusive but, if the DRV it works, a Linux approach will likely solve the problem.
Only thing is, yesterday my LG TV (yeah.. that one) was running pixel refresh and suddenly went completly dead - no video, no audio. The Power LED DOES blink 3 times before it goes dead as well.
I'm looking for schematics and technical data now. Dang! Is there a LG hardware forum out there?
Again, many thanks
Michael
