Olevia LT42HVi - Need to toggle power switch on...

Question

We have an Olevia LT42HVi TV connected via Verizon FIOS. Almost reotuinely, the TV will not power on or off via the remote OR the Power button on the front of the TV. If you simply, toggle the on.off switch on the back of the TV udner the power cord, the TV power and remote then work. Is this a fuse problem that requires a technician call? I tried swapping out the Power strip and also just plugged the TV directly into the wall. No differrence. The TV is 14 months old.
