It's not turning on j have tried so many power supplies what should I do now
It's still not turning on or showing the red light what can I do now to turn it on
Since you've tried many power supplies but making sure it's at lease 5v with 2 amp. Connect the box to tv whatever the input is see if any progress, some time it's working without the red light's on.
If nothing shows then your box is dead, but last try to unplug and plug few time see if it helps.
