Here is my config if somebody points out any similarities:
Power supply is an original Raspberry Pi PSU (5.1V 3.0A) (Slave socket of the surge protector, so it turns on only when the TV is switched on)
This really caught my attention.
If you're powering on your Raspberry Pi at the exact same time that you're powering on your TV, then it may not display an output on the screen. For this reason, I strongly suggest that you don't use the switch, on your power strip, to turn on the TV and the Pi, at the same time. Instead, make sure that your TV is turned on, and the screen is expecting a signal, before you plug in your Raspberry Pi.
My suspicion is that the solution is something this simple. I'd be surprised if there are that many Raspberry Pis that are so defective.
This, also, could explain why it may have been working fine, one minute, but then it doesn't seem to work at all, the next time you boot. You may be dealing with a race condition, where, sometimes, the TV turns on fast enough to expect a signal, before the Pi produces one. While, other times, the Pi starts booting too fast, and beats the TV.
So, just make sure the TV is on, first, and is expecting a signal, then plug in the Pi.
