    I recently started to install a vista 20p system in my house to replace an
    existing system that was 20 years old at least. I am a novice but enjoy
    learning about this stuff. I bought most of everything used or new on ebay.
    I am in the process of getting all hooked up and turned on a 6150rf and
    found a problem. I can get the unit talking to the vista but the display is
    very hard to read. It seems like all the words are on but if you get your
    eyes at a certain angle, it is not all on and in fact it faintly shows what
    it is supposed to show but only when I have my eyes at the right level. I
    thought there was no backlighting but it turns out that it is on but only
    noticeable in the dark. Is it toast or is there something that can be done.
    I don't have the wireless stuff working as yet so I can't speak to whether
    that is working.

    the keypad needs addressed to 16 0r 17 on the key buss push in 1 and
    3 at same time see what address is many come defaulted at 31 . if
    defaulted to 31 then you need to program it so it displays properly.
    upon power up push 1 and 3 then set address and push star.

    Thanks but got that part done, I think. It is addressed as 17 and the vista
    P is set so it sees it and I can operate system from this keypad. I have a
    6160 addressed as 16. Problem is just the display.

    I'm not sure I like the sounds of your keypad - that backlight shouldn't
    need darkness to be noticeable.

    The first thing I would do is take it apart and make sure the display
    connections are all clean and tight.

    I don't have a lot of confidence that this will fix it but it's always
    possible and worth the effort.

    Also possible that you have a power issue but if that was the case it
    would probably be doing it to both keypads, though the rf is a bigger
    power hog than the other one. You could always try connecting it
    directly to the panel on just a few feet of wire - that can eliminate a
    few variables.

    Thanks for the note Joe, I think I may have found the issue but again maybe
    not. I took the keypad off the wall, disconnected it from the cable and then
    unclipped the board from the case. I lifted the board out and the display
    stayed in the case. Is it possible that the connection between display and
    board is a pressure connection between the board and the display. I put it
    back together and indeed the display is active but the same problem exists,
    I can read all the fixed english on the display except when I have the
    display square to my perspective. Also, the backlight, which works off of 3
    led's mounted on the board, does not seem to be lighting up very well.

    Do you think this is the issue with the keypad?THX

    Try connecting it directly to the panel with only a few feet of wire.
    That will rule out any problems you may have with the wiring.

    If the problem still persists take the keypad apart. Take the display
    board and everything out of the case. Examine all the parts to make
    sure you know where everything interfaces. Clean all the connections.
    You can use a cloth and alcohol or even a pencil eraser. When you put
    it back together make sure everything is lined up properly and that all
    connections are tight. If that doesn't fix it then I would say the
    keypad was being sold for a reason.
