One last detail is that when I connect my PS3 to the TV, TV shows that gets some kind of signal (as the "no signal" sign disappears) but I only get black screen.
Unfortunately, TV is not under warranty any more
The problem could be that the point in question is the one used for the protection signal. This is why the other devices probably work since they dont need the signal decrypted. This is the only thing I can think of. This will also explain why it shows a device connected but shows a black screen.
