I'll definitely check the voltages on that slider next time i open the her up again. Since the data slider is the ONLY slider or button that seems to have any effect on my unit, i suspect that i have a larger issue at foot here, but the data slider solder joint still merits checking.
Thanks for the tip, and the service manual!

The value/data slider does react when it is moved (LCD immediately goes from "11 8.8 0" to "80 00"), but that's the only one that produces any response. Since the buttons do not work and the rear TAPE switch do not work, i am assuming that there is a much more deep level problem at hand.

The single edit slider can get dusty also.I've heard the stereo delays come and go with cable jiggle during live shows and the program change numeric buttons sometimes jump up 2 or 3 patches past the target.

I have changed the power cable socket to the three prong style and replaced the internal battery. The unit powers up fine but i have no sound output at all. It is my understanding that this is a normal condition when the battery is replaced (no programs in memory so no sound).
