Ilo HD TV won't turn on

try another power cable (usually these tvs use the same power cords as a number of other electronics, such as desktop computers, etc) - if that doesn't work, try another power outlet - Also, try powering the tv on with the power cord out - this clears the static electricity off the system board, and helps w/ power issues sometimes - if still no power, then you can contact Wal Mart's customer service (since iLo is their in-house brand) @ 1-800-925-6278 to see if it's still under warranty or if they can put you in touch w/ an onsite technician.

Good luck - hope this helps!
