Does the tv make a clicking noise like its trying to turn on before the tv goes into standby and the LED starts flashing? I suspect this is due to a shorted component, most likely to be in the 5V(switching) line and just want to be a bit certain before we start testing the power supply.

Hi rschutt01,
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.

Usually Sony and LG Blinking Codes are the same. Here is what I have.
