Actually, think I may have identified the issue with mine. The 4435 MOSFET labeled as U1 appears to be the point of failure.

Did you ever figure this one out? On the larger board, it looks like the 4435 MOSFET near the red wire got cooked. i'm in a similar situation, looking for insights in how to repair this.

Hello and welcome!

My setup from the driveway. I've been experimenting with short exposure DSO captures using a planetary camera. Exposure settings determined through sensor analysis and smart histogram in SharpCap.

The mount has been completely rebuilt with new bearings and grease, but is still a work in progress.
