Darkness problems with my Technika x22/14c-gb-tcd-uk?
When I switch it on, the picture will come up fine, and normal, but then after a period of around 5 seconds, the screen will suddenly turn black.
However, the picture doesn't actually go off, it just turns extremely dark. If I angle it right, and with the right light, I can barely see the picture, so it's not turning off. The sound is completely unaltered.
I've tried the wires, it doesn't seem like any of them are loose.
