Sure this has been answered but I can't find it. Trying to get the circuit board out of a 5075N. Bottom off, pin connectors unscrewed. LGB diagram shows no internal attachment. Board not secured from the input/control terminal strip; moves up and down easily. Very secure from the control button side. Any way to get in to replace a bulb or switch?

There are a couple of those horrible sloppy snap in connectors, one each side. I destroyed on on one side to get into mine. You can see a gap where it has clipped into on the side.

As bodged with small holes for pins to hold in place

Hope I have the correct problem that you are asking about.

Thanks! Once the bottom was off and the pins removed did the board simply fall out? The LGB instruction sheet seems to indicate it should but this one is glued in along the edge opposite the screw terminal. The sheet (and the unit itself) seem to suggest the board is held in place by the pin extensions protruding from the bottom plate and pressing on the circuit board - which should fall out once the bottom and pins are removed. But this one is cemented in place in some way. Is that what you found or did your board fall out as I expected it should?

Ah, this is useful, I have a 5075 and a 51750 each with a switch which works interrmittently. I've been trying gently to prise off the base to get inside to vac round, but without success. Guided destruction seems to be the answer.
