I have a TRV82 with a C:31:22 error, un-powered it, smacked it a few times and it was a miracle. This was the fix, I too couldn’t believe it. Back in the old days I had a TV that I would smack and would work fine, who would think that high tech electronics would also work with a smack. Funny if someone smacked me I would stop working. LOL Thank you for the fix.
