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.

• Explore Scientific N208CF @ f/4.1 with HR Coma Corrector
• Main camera: Player One Neptune-C II (IMX464)
• ZWO 42mm filter drawer
  • Astronomik Luminance L-2 filter
  • Astronomik ProPlanet IR 642 BP filter
• Orion Thin Off-Axis Guider (TOAG)
• Primary guide camera: ZWO ASI290MM Mini
• Secondary guider for use with SharpCap polar align routine:
  • William Optics UniGuide 32mm
  • Player One Mars-M (IMX290)
• Celestron Advanced VX Mount with ADM Dual Saddle
  • 2x Celestron 5.4kg counterweights
  • 2x iOptron 1.35kg counterweights

To improve stability, I removed the stock handle and dovetail from the ES N208CF and replaced with a 15" ADM D-series universal dovetail bar. The mount has been completely rebuilt with new bearings and grease, but is still a work in progress.
