Contact the authorized service center for Zenith. The main power supply board to your TV has damaged.
If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

On the TV you need to select the port for the USB. You should have a source select button on your remote for this. If not it is in our video menu. Second, you have to make sure there is not a setting on our tablet that needs to be turned on for sharing.

Zenith Flat panel TVs usually only have two boards in them Plasmas have a few more, doing a visual inspection of the power supply capacitors usually reveals swollen or bulging capacitors.
If the capacitors look good, voltage checks would be needed to isolate the problem to either the main board or power supply. Check for 5 volts to the IR board (& or keyboard) , if five volts is present suspect the main board
If this TV has voltages from power supply , suspect the Z, X and buffers
