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.

check for bad capacitor in the power supply board and then check shorted component parts at the sustain board.

I have an LG TV 50PV450 Plasma TV, and after a storm last night, it won't power on, however,standby light remains lit, solid.


Look for blown capacitors on the power supply board. They will have domed tops instead of flat tops Some will look puffy too. You can get a repair kit if you're handy with a soldering iron or replace the entire board from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

Replacing coaxial input


Coaxial cables are all standard for that kind of TV. I'm about 99% sure on that so just go to a electronics shop and buy one and double check with the person at the shop but I'm sure you'll be save just replacing your old one with the same size!!!!

LG 36" plasma flat screen


If the main power supply has failed then the cost of the SMPS must be checked. If there is an upgraded version the compatability also must be checked.
Also spending more on a plasma TV must be checked as the cost of new generation TV's have come down. So a good estimation with a Guaranteed service solution is the need and not one which you can take a chance resulting in total loss in case of a failure or a problem further in the motherboard when the power supply is installed.
