    Default tips for gettin'ut the goodies

    I put this up today but I was told that due to the touchiness of the maker that my thread my need to come down ----so look while you can and copy whatever you want.

    UPDATE I took it down myself- better me than admin- anyone running into probs getting the thing apart can ask DTR or myself. There are only a few hidden screws and if you try you will locate them yourself.

    Here is a post from the other place. Anyone tried to get the power supply working?

    Then jumping pin 1 to either pin 5 or 6 results in a fluctuating voltage from 4 to 4.5


    If any one with better testing tools can see if these yield a good voltage please test this out. I only have this DVM.
    And some more good info.

    I believe the Power ON to the 6-pin connector is an input, and the one on the 16-pin supply is an output, as the former is the input to a photocoupler, and the latter appears to be connected to the collector of a transistor (?) Q102.

    The +5V is always on as far as I can see, and is used to turn on the power supply through the photocoupler-connected lead. The power supply might be be providing 12V as well, or just staying on because the power on is floating. I'll have to test it later when I splice the cables.

    Edit:

    Power ON on the 6-pin connector is active-low. You're measuring 4.53V because of the diode in the photocoupler and the resistor in-line. The anode (+) is connected directly to the +5V input on the 6-pin connector.

    Default power supply

    I'll give it a shot I have one of these power supplies around here somewhere, I'll dig it up and see what I can find out...

    Sweet let us know.


    Also has anyone noticed the temp sensor is now missing on the diode blocks. I cant remember the last time I have seen one? Are they just going without them now.

    Old projectors XJ-A140's


    Newer XJ-A140V's no temp sensor.

    Default Temp sens

    Yes I have noticed it's been gone for about the last 5 units.
    they must have located it somewhere else.
