Hello, I am trying to bring back to life my Toshiba 55U7863DG, which has never been the most reliable device - keep on annoying me with its slowness and some random start-up/shutdown issues requiring to unplug the AC. But yesterday it finally said goodbye and decided to not turn on again. Green light is blinking, I've seen this behaviour before and thought that these are some temporary whims again, but unfortunately not this time.

I have checked that my TV is build based on the 17MB130S board, which seems to be quite popular and easy to buy as a used one. Still I would like to ask...
