After 4 years of mostly happy use, last month the TV wouldn't turn on at all and got a new mainboard under warranty. Initially it appeared to be fixed but over a couple of days it became clear that, without a soft restart, (long press on power button) the display was completely blank on all inputs. Back around the warranty claim I go and an engineer is going to come soon to replace the main board again.
It seems unlikely that a second replacement board is going to solve the problem and software seems a more likely cause - anybody here experience anything similar and / or have suggestions?
Thanks in advance.
