So I got a chance to try a mainboard replacement, but the behavior is still the same. Funny thing - first I got the wrong board (BN41-02751A instead of BN94-15257K). They actually look identical, so I installed it.

When turning on the TV, the welcome sound played, but I only got lines on the screen.
With the replacement board (the right one this time), I cannot get any sound or picture, just backlight.
This seems to me like a T-Con problem, but I don't think this TV has one.
