Report "When I turn the rcx400 scope on (from park position) it will rotate in the R.A. direction (as it should), "but" if the ambient temp is (approx.) below 50 deg F, when it has stopped it will not move in the DEC direction (only move in R.A.).... However if I remove the DEC housing and "push" on the circuit board, it will again move. I have drilled a small hole in the DEC cover and when the temp is belw 50 deg, I push a pencil through the hole to press on the cicuit board and the DEC will then move o.k. What is the problem? Loose conection, cracked circuit board, ??? I tried to push on all connections to make sure they are seated, but does not fix problem...?"
