    I did a Google search for Mondo Stinger LED and the manual states:

    8. Exclusive power pilot LED resolves the question of whether the transmitter is getting power​
    and is “on.” The LED is on only when the switching power supply is functioning. This means​
    that the LED is only on when the unit is properly powered and the input voltage meets the​
    minimum voltage requirement as set by the battery saver selection switch. (See #10​
    below)​

    You can find the manual at http://www.iftrontech.com/images/media/MST5.8-User-Manual-Rev-B.pdf
    It doesn't seem to explain why the LED would be flashing, although it suggests that there is a power supply problem...as it does suggest the LED is a simple "on when the unit has power."

    On the Mondo Extreme 1500 mW Tx, the data I found (well, Mrs. Google found) is:

    On Board LED flashes for:​
    ● Number of cells detected upon power-up.​
    ● Battery low​
    ● Temperature too high (Fan blocked, etc.)​
    ● Immanent shutdown due to catastrophic over temp​

    See http://www.rcgroups.com/forums/showthread.php?t=1656554

    That all said, you might want to contact IftronTech at http://www.iftrontech.com/contact_us.php (or just email to info@iftrontech.com). They've been very responsive to me when I've emailed (my contact was Ira Faberman, but that was back in 2013 so I'm not sure he's still there).

    Hope this helps.
    Andy.

    Check the iftrontech website on the stinger/yellowjacket. If you don't see an answer give them a call. Ira the owner is very responsive. Sorry I don't remember the light indicator on the FF HDMI unit.

    Thank you so much Gary and Andy. I'm grateful for you lads going to the trouble.

    I managed to solve my particular issues (there were several in series). I had some whacky programming, and the channel coming off the PCB Ext to feed power to the video link components was set for flashing (like nav lights). So, the flashing indicator lights on the Stinger and HDMI-conv were responding perfectly to the power on-off cycle they were receiving.

    Once that was solved, I had to debug the convoluted wiring on my yellowjacket to monitor loom. All is well now.

    So in short, my FF HDMI converter works fine, although I'll second the terrible mechanical connection of the HDMI plug. I've re-soldered the feet and epoxied it down like Tommy did. I'll also 'permanently' zip tie a cable into it.

    As may be apparent, I've bought a second hand rig, and am concurrently learning this tech, and how what the previous owners have rigged it.

    Excellent! I guess the LED really was telling the truth!

    Computers and robots apparently can't lie...

    Nor can they tell the truth. :)

    This is getting complicated. I'd better consult Asimov...
