I am not a tv person but your mention of I2C lines reminded me of a long struggle with a Sony set. I didn’t have a scope at the time but managed to ascertain that the I2C was misbehaving but which of several chips could be responsible? Turned out to be a (spike protection ?) zener on the line which had gone partial short (3v ish rather than 5v6) leading to indeterminate logic states. Worth a check.
