Hi group....

Here's a baffling one...
I have a fully functional SDS7 (Ser# 71163) with an intermittent issue... when powered ON, sometimes the Front 2 digit LED Display above the Increment Knob on the Control Panel does not light up despite everything else normal. All buttons and LEDs are fully functional.

I've removed the Control Panel and tried a different one and cable that are known good.. and the same results. Out of 10 attempts, the LED remained unlit 3 times. I suspected a power supply issue and tried a different one with the same result. I've also tried the suspect Control Panel in another SDS7 and it worked fine, lighting up 100% of the time.

It appears that there might an issue with something on the SDS7's main board or other issue with the supply that powers the 2 digit LED display??

Thoughts?

Cheers
Alan
