Is there a way to check if JYE117 is working correctly?
When JP2 shorted and powered by the USP everything works correctly. But when I unshort JP2 and momentary ( with the USB pluged in) if I Press the adjustment switch the oscilloscope only momentarily turns on , The LED on JYE118 blinks brightly and then is dimly lit. JYE117 acts as if it will not latch on. However if I momentarily sure JP2 then JYE117 will latch on. Once on, the oscilloscope will turn off if I press the adjustment switch for a couple seconds.
Is there a way to test JYE117 is working correctly?
Is there a way to get another JYE117?
Any ideas will be helpful.
