Dolphin M5 (green) out of order.

On start, it does his 1/4 turn left and right, then stops while trying to start the pump.
I tested all 3 motors: OK
Conclusion: The board has a failure.
Is it still possible to find one?
Mine is labelled:
"dynamic premium MAYTRONICS 2410110LF rev03", and a sticker on the square chip says: "BIO 2013 55A7"

Or may I mount an M500 (blue) board?

Thx a lot for replying.
