    RP3700

    Hello everyone

    I recently retrieve a RP3700 out of order.

    I didn’t know since when but the previous owner said to me that the power supply is down (the part Power Supply Unit IX-H200 was dissambled of the RP). I re-installed it and made all connection, but nothing appened, no noise, no signal, no blink…

    I would like to know, how I can be sure about that the power supply is dead ? How to proceed (if they are some test to do / or check some part, like fuse…) ? What parts I have to check with multimeter ?

    Thanks a lot in adavance,

    Have a good day

    In the power supply there is a standby board, usualy it is necessary to change the STR G6153 chip on it

    Hello

    Thanks a lot for your answer, it's a good beginning for me.
    I checked the component and it seems to be a bit blackened, but I'm not sure about that. (you can see the picture in the attachement, there is a bit of dirt on the circuit around this area) My question is : can I do a continuity test on this component to check if it's dead ?

    Thanks,

    Turn on the risograph.
    Try to use hot air at this place, for example from a hair dryer.
    if after heating the risograph turns on, then it is likely that STR G6153 should be replaced.

    Thanks !!!! You made my day ! It's working the risograph turn on with hot air. I will have probably other error code but it's a really nice to see the screen on and hear some noise from the RP
    Thanks again and have nice day !
