The error code means
22-2A 7IC1, SDA5273P Analogue Teletext processor which is not related to your problem.
The error codes generated reflect status of various data buses and microprocessor connections, but cannot reflect the status of a missing EHT voltage unless there is lack of driver signal which would almost certainly effect other functions of the TV.
Given your comments in your previous posting on the subject and my response about dry joints, this is still the most likely problem area around the EHT transformer/ driver components..
