Doesn't matter. TV LED is not lighting also. Because I can't find MB, I am planning to use TV LCD panel for future project.

if you still have TV you could try put the firmware on USB and turn on TV maybe is searching for correct files or get from some rooted TV file with name SubMicomEU.bin or something similar and try also with this file. Could be useful or don't, I don't know, I never tried. I have this file on usb st...

Yes, from service menu. I just saw "Upgrading"... and nothing more happened. Where I can find information how to fix my TV?

Hello,

I tried all ways to fully reset my F5410. However, after TV power off old channel information always came back. When I found INFO – MENU – MUTE – POWER feature and run Upgrade... However, after that my TV looks like totally dead - no red light, can't power on.

Any ideas or solution?
