Greetings. I have spent quite some time in this monstrous thread and I haven't come to any conclusions about the orange light issue for the TX-47F430S. This TV has been an almost flawless workhorse for 8 years, albeit with some burn-in from the senseless, non-floating info box. Now, I have the orange light with no power. My symptoms are: I took the stand off and mounted it on a wall mount and upon hooking it up, had the first orange light with no power-on. I unplugged and plugged it 10 or 15 times, held the power button, etc. all the typical attempts at a firmware reboot. Didn't work and walked away from it. An hour later, unplugged and plugged the power and it came right on. In a wonderful coincidence, had a power-outage that very same night, and haven't been able to get past the orange light again. Is there any way to know if I have a firmware or a cap issue from these symptoms?
Thanks to all the contributors.
