My box is not booting up at all. Unpacked x5 firmware files for AML V3 box, followed instructions on full factory reset, e.g. card in, power off, pin inserted and power on. No boot loader coming up at all. Strange.
I’m having the same problem with mine, no output to the tv at all, display on the front of the box stays black the box seems to power on i.e. the red light turns blue but thats all it does, tried the sd card on both formats on both the V3 S and the V3 software versions, nothing, note unit stays cool now when normally it runs rather warm, i have been in touch with support and it looks like my box will have to go back for a repair or replacement.
