Question about JVC Televison & Video
So from what you say the flat LCD JVC TV has a main power switch that you turned off and after power was restored you turned on the main power and also the other power switch (or remote on) and nothing lights up at all, not even the power light. Sounds like the power going off may have blown the internal fuse, or damaged the power supply.
you can open the back and see the power supply which has a wire running from where the AC goes in, check or replace the fuse located near the AC wire. if the fuse is good do a visual or the board for capacitors that look swollen or exploded. they can be replaced.
if good fuses and caps, then you need to measure for 5volts , best place if its not makred on the board is on the remote reciever sensor.
If 5 volts is there the power supply is probably Ok and the other board (signal board) is bad. there are only two main boards in most LCDs.
Hopefully its something simple like the main switch is have on or a blown fuse.
the circuit boards cost about $350 each, if the TV is under 1 year old you can get it fixed under warranty.

Please unplug TV from wall socket for couple of minutes, replug back in and turn ON.
If still does not power up, try it in another wall socket.
Also check standby/ power light flashing or its solid at TV.
If standby light is flashing or its not lit then TV got power supply problem and requires qualified TV tech. I hope TV is still under warranty so ask for warranty cover to store.
