I've been running my SX 814 Pro a couple of years but after a short break I've been having issues with the bin1 data from the camera. Also the bin2 data looks weird.
The bin1 data is completely black, zero histogram and not even any sensor noise. The bin2 data does have some data in it and does show a histogram. But the image itself looks awfull. Shown here:

Tried multiple things to resolve the issue:
- reinstalled drivers
- different usb cable
- different power cables
- different laptop
- different power supply
Both coolers do kick in and the green light lits up after plugging in the power.
Now on the bench during the day the weird thing is that if I unplug any power and download bin2 data the histogram does show some data in the histogram with or without power. The bin1 doesn't change and stays black. It's like the sensor isn't getting any power passed on from the main board during bin1 operation.
Does anyone recognise this issue?
