Hi there, thanks for the info.


The problem is a fault on what is called the P-board of your LCD TV. See page 34 of the following document.


You can buy the part here.



I would consider all this good news. Your Power supply board is only 40 bucks. I am always pained when I have to send a replacement power supply to someone with a Plasma that costs over 500 for the part alone.


Alot of times you can find failed caps on these things by seeing which ones on the board are "buldged" on the top, but in your case since this part is so cheap, I recommend buying the board and replacing.


A person with reasonable technical ability can take the back off of this TV and do this themselves. Might be a good idea to take pics along the way to make sure you reassemble everything properly.


Good luck,
