your power supply needs new capacitors!

Unplug the set, press power and hold for 60 seconds, let it sit for 30 minutes and plug the TV back in, try to power on, if no change! the problem is power supply or high voltage issue.

Very good TV. Since this is LCD there's not much that goes wrong with them except their internal power source. You will have to get it serviced. It is not something you can do without the expertise.

You have a power supply fault. Look for short circuit diodes.

MAY BE PANEL LAMP BAD

Instead of just unplugging the TV, perform a power drain:
1. Unplug the product's power cable so the device is not grounded to the house. 2. Press and HOLD the product's own power button for 1 minute to drain the capacitors. 3. Plug the product back into a wall outlet and try to turn it on.
Note: This procedure works with battery operated devices as well so remove the batteries and hold down it's power button.  Electricity can remain in capacitors and on circuit boards enough to prevent normal functionality. By clearing the residue electricity, your product will have a fresh start and many times this will resolve a buggy or non-responsive device that appears to be dead.
If the TV still won't turn on, then it appears something is wrong with it's mainboard since the TV is still receiving power because the standby light is still coming on.  The cost of fixing an older TV's mainboard could be costly or impossible if the part is discontinued.

First off, try a power drain:
Unplug the TV's power cable so it is not grounded to the house.  Then press and hold the TV's own power button in for a minute.  Plug the TV back in and see if it works. If it sill won't work, are there any visible LED lights you can see in the back of the TV?  You need to determine if the TV's power supply is shot or the TV's mainboard.  Service would likely be required if the TV still won't turn on.

as you say it was ok before it was moved. so thre is a possibility that some parts must have gone loose while shifting .
