I followed your instructions and found a board on eBay. Sorry you didn't make any money off the deal but I did give you the offer. Working great! and now I have 9 spares.

I have the same issue on the same model number. Wonder how much an inverter board cost and how to get one.

What if the transformers are all good? I did check all my transformers and all are Ok. Thanks
