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 for your advice and check if there any specific requirements on these boards compatibility ?
I was trying to run the firmware upgrade, prepared the USB stick with the required files (4) and pressed the ‘OK' button following the instruction, but there was no reaction - there is a chance that the files which I've found are not the right ones.
Please find the photo of the label attached below, including the serial number, as I heard it might make a difference.
All information are more than welcome and I would like to thanks for your help in advance!
