Panel fault, failing edge driver causing lack and delay in horizontal scanning not fixable sorry. All Samsung panels seem to fail with horizontal scan issues

are you sure? because the panel work fine when is cold, but then in the next 20 minutes the problem arise again with the same pattern.... if this was a panel problem, this should not be a permanent fault?
