    Hello guys,

    I asked this same question on the manufacturer's forum a couple of days ago, but I got no answers.

    The thing is I have a TV dongle (Rikomagic MK802) and the WiFi suddenly stopped working after a blackout. I did all what I could via software, but the problem persisted. So I opened the device up and I found 2 components that seems to be burned out.

    Can you please take a look at the attached picture and tell me if I'm right and if you can identify the components?

    Thank you!

    That looks like some kind of epoxy or glue.

    Sounds like it could have been a power surge but, the power supply would have to be effected as well..

    Below the red power cable there's a 0ohm resistor, is it open?
