Hi Jeff,
I feel sorry for you. It must be a horrible situation. :-( I hope that the board will be repaired quickly or that they will send you a replacement.
Have done a little research, which I hope might be of help.
I discovered this webpage on Europa.eu:
https://europa.eu/youreurope/citizens/consumers/shopping/shopping-consumer-rights/index_en.htm#I clicked the appropriate buttons - for example that the item was bought new Online, from a retailer and so forth. You can do the same and find out what rights you have. Here is an excerpt of what I got as a reply:
If goods you bought anywhere in the EU turn out to be faulty or do not look or work as advertised, the seller must repair or replace them free of charge or give you a price reduction or a full refund. You can usually only ask for a partial or full refund when it is not possible to repair or replace the goods.
Under EU consumer rules you always have the right to a 2-year minimum guarantee at no cost, regardless of whether you bought your goods in a shop, online or through distance selling, such as from a catalogue or by telephone. This 2-year guarantee is your minimum right, however national rules in your country may give you extra protection. and...
If your goods break within the first year, it is assumed that the problem existed when you received the goods, unless the trader can prove otherwise. Therefore, you have the right to have the goods repaired or replaced free of charge, or if this turns out to be too difficult or costly, you may be offered a price reduction (on your original purchase) or your money back.
In some countries, you may have the right to choose freely between these different options. The trader always has to provide a solution. In some EU countries you also have the right to request a solution from the manufacturer.
