Daikin PCB repair or replace

RX09NMVJU FTX09NMVJU
About 4 years ago I DIY installed this unit, 2 years later the PCB board failed L5 and I had to replace it, less than $200 IIRC. The board has failed again L5 and Daikin no longer manufactures the board and now it is in the $550 to $600 range. Only 4 years old and no longer supplying parts. Not likely that I would recommend Daikin to anyone.
Is there another source of boards or is there someone that will repair the 2 failed boards I have.

I'd replace the board at $260. Do you have the unit on a surge protector? Not sure you should have went through 2 boards that quickly. If everything else checks, out, I'd spend $260 on the board and $50 on a surge protector for it if you don't have one already.
