Samsung On/OFF problem. Bad Power Module?

My 14 month old LN52A750R1F has the same on/off problem as others. So I have spent the last couple days researching this issue. Since Samsung isn't interested in fixing their problem, and they won't repair it under warranty, I decide to take a peek at the capacitors on my power module. The board is a BN44-00201A SIP528A Rev 3
The caps look normal, not swollen like I was expecting. I searched and found a new board from discount TV Parts for around $90 shipped. It should arrive here in a couple of days. I will swap the complete board out instead of soldering in new caps.
I'm worried this won't fix the problem, since I read a post where a guy swapped in a new board and it still cycled on/off.
If mine still is not working, I will swap out another board or two until it gets fixed. Then I am going to change jobs to a TV technician:-)
I'm really disappointed in Samsung. I will never buy from them again, and will spread the word. I have filed complaints where ever possible.
