I bought this tv with it needing a new dmd chip, a couple months after that replacement the lamp went out. With the new lamp and dmd chip the tv worked great, except for a couple bugs with the inputs. I have some aspects of my OCD I haven't been able to kick and the organization of the inputs on my living room tv is one of them. There were duplicates of the input devices and they didn't match what I had hooked up and I couldn't change them so I figured hey, there's an 11.03 update. Maybe that's what it needs. Nope, it bricked my tv. I performed the format and the unzip correctly, I waited for the tv to fully power down and I've repeated the 3rd through 5th step I don't know how many times. The green light blinks green with the blue welcome screen and it does not shut itself down. DIY trouble code shows no failure. Yahdayah. All I can find is that it's more than likely the main board. My primary question is, how do I undo whatever I did. If the answer is I can't then my next question is, how could the update have ruined the main board in this tv.
Corrupt or wrong firmware will make the board seem bad to diagnostics. Do you have or can you get a copy of the old version firmware? If so I'd try to restore it. You also might try re-downloading the update (after triple-checking that you selected the right model.)
Beyond that there's a chance (albeit unlikely) that tech support might be of some value, specifically I'd ask if they've had many reports of problems with the latest firmware upgrade, and I'd insist they provide me with a copy of the old version -- even if it's not on their web site you know they still have it.
Since the update facility is still apparently operable all may not be lost, it all hinges on obtaining firmware that's valid for the hardware.
(Note that It's possible that a portion of the flash memory has failed and can't be rewritten, in which you are likely screwed.)
