Communication Error
TV micro (on AG board) is communicating with EMMA2Lr (on FB2 board). If EMMA has any problems, TVM retries to communicate and
waits the response of EMMA. It will be timeout in about one minute, and TVM start power-up sequence without communicating with EMMA.
Then, picture appears, but No OSD.
