How did you find out you have to lift the motherboard at all?! It has its stable place by screws on the chassis of the TV. All you have to do is check for broken solders where the ribbon cables begin. You must use magnfying glass, they're too small to see something like a crack on them. The fact you move the motherboard and the picture changes it's quality tells that there's some weak link with the other boards and those connections are made by ribbon cables, directly sold or connected via sockets. In both cases we have solders which must be checked. That's for now.
