    Hah! I think I have an occasional problem like that, too. (Possibly
    loose HDMI cable, in my case.)

    In my case the machine (a streamer box in the living room) is on
    pretty much all the time, so the manifestation is the video signal
    occasionally disappears completely.

    Remembering that you need a 32 bit (not 64 bit) version of your chosen OS.

    An elderly Pi2B v1.1 seems to have quit running. On power cycle
    both red and green status LEDs stay on, no flashes. Roughly one

    the microSD card has no effect, unseating the microSD card has
    no effect, swapping the microSD card has no effect.

    Plugging a usb cable into the usb ports and connecting a voltmeter
    to the red and black wires shows an initial 5 volts, then zero,
    then 5 volts after a few seconds. Putting the meter on the power
    supply leads shows 5 volts steady.

    If I power cycle the Pi2 while the monitor remains powered
    and only a USB keyboard is connected the monitor shows the
    rainbow screen, about a page and a half of boot output, then
    blanks and enters "no signal" mode. The keyboard responds
    to caps lock.

    Can anybody suggest other things to test?
