Try a new/different power supply for the aandroid TV. It may have bad capacitors on the power supply which is especially problematic if you have a poor source of wall power.
Check your outlet...
1) Measure the voltage at the outlet
If it is ok for your region of the world,
2) get a volt meter that measures min/max and measure your outlet to see sags when you turn on the power. If so, you need to check other outlets to see if it is your whole house (and you cannot do anything about it). If it is limited to a few outlets, you have a structural problem.
