1) Power Error (R ED 2 tim es blink )
This indicates POWER Error, Low B error of 12V from G6 board. TV Micro (on ACW-TW board)
monitors pin79 and pin138 to detect POWER_ERR and shuts down chassis power to
Standby status.
monitors pin79 and pin138 to detect POWER_ERR and shuts down chassis power to
Standby status.
TV Micro pin138 Normal condition : Low / Error case : High
TV Micro pin79 i_lb_err< 0.7V(PW_ERR_LEV)
TV Micro pin79 i_lb_err< 0.7V(PW_ERR_LEV)
- Check 12V at CN 1000 on ACW-TW board. And F1001 on ACW-TW board has 12V or not.
- Check G6 board.
