I have an EXT80-AT TC that apparently has a dead 494 controller. With batteries installed, the red light comes on in the motorized mount, but the controller does not function at all. No LEDs light up...nothing. I did pop the controller apart too see if anything was obvious inside, but all appears like new. The spiral cable appears good as well, not even any stretch in it at all in it. I bought this second hand from the original owner and she said she had only use it a few times and everything worked. I believed her as the scope had the appearance of being like brand new when it arrived.
Has anyone had experience with this particular problem and any pointers as to what I can check? I have been all over the internet, weaslers site, etc., to no avail.
I am trying to avoid buying (if I can) another used 494 controller online just to find out that was not the problem or that the next controller could have possibly arrived DOA as well, since the 494 is an old model. They are pricey and I would be in the same predicament that I am now (how would I know for sure if it is the controller or the drive?). BTW: I do not know anyone with a controller I can try. That has already occurred to me.
Just looking for advice I suppose, before I lose hope and toss it in the dumpster. LOL.
