From what I can tell it's a 19" LCD TV with a built in CD player.
What are the Warranty rules in Australia?
What can you try?
Not a lot really - plug something else into power socket to see if there's power available. Check the fuse in the plug and if you have no method to test it "borrow" a fuse from another plug as a short-term test - swap the fuses back to their original place immediately after the test.
The days of bashing a TV set to make it work are long gone - but you never know - it may be suffering from a bad connection deep inside but i doubt it.
Also gone are the days of an engineer coming to you and changing a failing valve (vacuum tube) - these days it's take it to a workshop where they diagnose major (expensive) components to replace.
Check the market for a new replacement
