I tries to find one and as far as I know Their is no schematic for both motors after weeks of looking , I tried to make one but the board appears to have hidden parts in the middle of it and gave up.
Thiers all kinds of YouTube video and forums, how to clean and rebuild them Xraytony has a video for the take up reel for the CT-F1250. Not it hard to do but need to be really careful. Good Luck
