    Hi All,

    Does anyone have the service codes (access to the service menu) for the Hitachi 42PD5200?

    Thanks in advance for any positive responses...

    Regards

    Hi,

    Did you get anywhere with finding a service code for Hitachi plasma?

    Thanks

    I did obtain the code to enter service mode but as it turns out, not a lot of use. It did however enable me to switch on the RS232 interface but the display does not appear to understand RC5 codes through the serial interface.

    If you PM me with your e-mail address I can send you the information I eventually received from Hitachi....

    Regards

    Be very careful ! The last person on here who played with the Hitachi service codes ended up switching off his remote control :eek:

    (Not me, I might add).

    Yep. That is noted on the documention from Hitachi. The serial port will lock-out the remote function when in use, where the serial port gets a "open" but no "close" command the remote will remain locked.

    Yes,

    that person really switched off his RC. But in the same time he promised to fix that and come back here with that fix - and here it is for your pleasure :D :

    In the Service menu, change the register 175 from "0" to "1" - it turns the RC on again and everything's OK :smashin:

    TBH, I have a few more hints in this regard, but no time to post it at whole

    Now, if someone can find the register to make the TV display 720p/50, I'll sit up and take notice :D

    Here is a link for RS232c application notes from Hitachi Europe. The right bit settings to enable or disable the RS232c is on the register location 180 - 0:disable 1:enable .

    Link to Hitachi's correct document (Right clic + SaveAs)

    To enter the service menu on plasma panels for :

    • 32PD5200 / 5300
    • 37PD5200 / 5300
    • 42PD5000 / 5100 / 5200 / 5300

    Using the buttons on the plasma :
    1. Switch into stand-by mode
    2. Press Position Down and Input buttons.
    3. While holding these buttons, press and hold Power On button until the Service Menu appears (5 sec)
