Quote:When you get both no response codes it is usually a connection problem between the HC and the MC board. You should look at the socket that the HC connect to the mount. Make sure the fine wire contacts are aligned correctly. With the mount turned on, wiggle the HC connection and see if you get a response. You could have a bad connection inside the HC or inside the mount where the Power board connects to the MC board. Also wiggle the full length of the coiled cable on the HC. There could also be a bad crimp on the RJ connector on the HC cable. I would not condemn the MC or Power boards yet.Stan

Quote:After removing the MCB from the freezer and reconnecting it as quickly as I could, the scope failed within 30 seconds of manual slewing. Was working fine before board went into freezer in the garage temperatures. I'm sure letting it warm up will result in it working fine again. I have some pictures of the MCB and some things I found odd. The solder connections on the capacitors look hand soldered, and the weird powder looking residue on the opposite side of the capacitors, and a surface mount resistor I believe. Not really sure what happened here but it seems to be effected by temperature.Think I might have any luck in resoldering the bad looking connections?
