HEQ5 upgrade
I got an HEQ5 recently, and today got the upgrade to GOTO. Did the swap over of parts etc, and all went flawlessly (left the illuminated polar scope off - don't use it).
Turned it on, no problems, except after about 4 seconds of being on, I get an electrical high pitch hiss. I thought it may have been tracking, so turned that off. Nope, not tracking. Took off the covers again and listened, and it comes from the board (like a capacitor or something). Unplugged the board connector and replugged it, same deal.
Do these routinely hiss like this (quite high pitch), or should I be contacting Skywatcher/Tasco again to get a replacement board? It functions FLAWLESSLY in RA and DEC (superbly in fact), just the hiss is rather annoying/disconcerting.
Opinions please.
