I have the same problem, to boot off/on a main switch. Type of faulty capacitor in power, but I can not find a pattern.

I have this problem too, anyone can help us. Is there a capacitor C... like the duo have which can make such trobble. Would be very kind to get an answer?

Three boxes all die at the same time?... how odd. Are your boxes clones?

My genuine is working fine. Can I ask you post output from serial console so we can see what is happening.

Hi ,
1. Turn Off box from power switch for 5-10 min. and then ON . Box will boot normally .
2. You need change capacitor like the duo.
3. UNO Box is life again !

and check POWER Board for bad capacitor like this

Thanks for the pictures. Very helpful.

The replacement of the capacitors did not help me, but it helped reinstall the bootloader (FPGA update) even though it was the right version. I downloaded TS_DAT from vuplus.com.

My UNO board looks a little different on the bottom right side of the board near the HDD...and the C856 capacitor spot is empty with no capacitor mounted there....

99% there is a problem in the mainboard. You need a good electronic technician to change, very likely, some capacitors.
