Argon One V2 daughter board video failure

I have two argone one V2 caes with raspberry pi 4 2GB models used as Libreelec TV boxes. One is now failing with bad HDMI ports. The pi (removed from the case and connected directly) works fine with the existing cables. I plan further testing. My question is can the daughter board be purchased separately as a replacement or repair part. I am beyond the 3 month warranty period. Please email a response as I will not have time to track the forum.
