The power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
Good luck in solving the problem, and do take care in handling the fault, because it contains high voltages....

If the standby light is on and it does not respond, it is most likely to be a problem with the power supply . First try this, unplug and leave the set like that for a few hours. Then plug it back in to see if the tv attempts to turn on when you try to power it up. See if you hear a "click" even if it goes back to standby. Let me know what you found so that I can help you test the power supply board to confirm, if necessary.

This kind of symptoms is an indication of out-of-regulation condition on the power supply board(this is where the power cord's directly connected). It is caused by leaky/dried electrolytic capacitor. It will dropped the normal working voltage of the power supply and disable the unit.
Leaky electrolytic capacitor has a physical indication of fault like bulged/dome at the top and can be easily identify through visual inspection. If your unit is not under warranty period, take off the rear cover and inspect the capacitors on the output of the power supply board. Once found replaced it with same capacitance and working voltage that is printed on its body itself. Upgrade to higher working voltage is another option. Watch the video below for more info regarding electrolytic capacitors.
Dried electrolytic capacitor has no physical indication of fault. You must have a capacitor checker to determine its condition and pinpoint the faulty one. If not available, you may replace all electrolytic capacitor on the output of the power supply, it will not cost you much because this is one of the cheapest part on this board. Another option is to replace the entire power supply board for your convenient, it will not required any soldering. Click this LINK for the replacement. I would advice you to double check the actual part no. of your board that is printed on the white sticker on the board itself to ensure you will get the right replacement upon purchasing.
Let me know if you need further assistance.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
