Depends on the reset. 1. Unplug power cord wait 20-30 seconds plug back in. 2. total reset hit the little red button for 5-10 seconds then reprogram your unit. This red button on my unit is marked reset, and can be found by the HDMI and power plugin. on my stick it's by the power plug-in. Hopes this helps
I'd be happy to take a closer look to see how we can help.
