NEC E424 RS232 Not working

I've created this module in efforts of adding on to it, but I can't even get the power to work. I've tried using ASCII, Hex, and a combination of both. The power codes, directly from thier manual, don't work. When I power the TV on manually, the HDMI input code works fine.
MODULE_NAME='NEC E424' (DEV dvTV, DEV vdvTV)

    If the input command is working then you know the baud rate and the cable is good.

    The power strings look correct. They are the same for many (if not all) of the NEC E series TVs.

    I had a power issue with one of the E4 series TV but I don?t remember exactly which model it was. Power ON didn?t work anymore and power OFF was actually doing a power TOGGLE. NEC confirmed it was a firmware bug. I don?t know if this is the same problem that you are experiencing but I would issue a power OFF command when the TV is OFF and see if it turns ON.

    I would also make sure the energy mode is turned off if it is not off already.

    And lastly I would cold boot the TV as that sometimes fixed the RS-232 comms.

    Good luck.

    NEC e series com port is very problematic, you may want to disconnect your TV from power source then do factory reset.
    Also download PD comms tool (http://www.necdisplay.com/support-and-services/pdcommstool/downloads) to test rs-232 commands.

    I've had nothing but trouble with the E series units. Even their own test program gets errors trying to control it. If it isn't ready it will reject your power codes. I finally started sending the power on/off codes 4 or 5 times with a wait between them to get them to turn on and off.
