I have a G810-2M that I just replaced the FBT in. I've adjusted the screen and focus controls, but can't get a really sharp image as compared to a newer G810.
Are there any other focus adjustments or any other type of adjustments on the board that can be used to fine tune the focus?

Hi if the FBT was an aftermarket replacement some times the 2 focus wires have to be reversed.

I forgot to mention that I've already tried this and have the wires hooked up for the best focus.
