HOTA D6 Pro Charger Repair

I replace the encoder board in the HOTA D6 Pro battery charger.
Thanks to Serge at www.PyroDrone.com for sending me donor units for parts!!

Thx mate, would never found the 2 screws under the display!

I have the same problem but mine was both buttons. I do not need to replace the board or encoders to fix it. I sprayed electronis cleaner directly over the encoder and press them repeatedly. Repeat a few times, re-assembled and both buttons work perfectly

awesome job. I got a pair of bad hotas, making me want to try to make 1 working one with them.

These are quite well built and not to hard to work on. After the AC power supply mine failed - the charger still worked from DC - I replaced it with a slightly higher power one in the same size from CUI sold by Digikey. The problematic rotary encoder works a bit better after quickly spinning it in both directions for a while, probably by cleaning the contacts a bit.

Do you have a link to the replacement power supply you used?

Seems reliance on donor boards is a fate for many electronic devices at today. Because there is no chance to get circuit and PCB diagrams and especially - firmwares for myriad of controller chips used in them. Good job BTW.

NICE!

How much do you charge my A\C power went out.

[@runngunrc1991]

Mine just cut off while balancing any ideas?

I have the same charger but my fan stopped working and will only charge at 0.2 amps
