Samsung PN43D490A1DXZA

I've browsed the forums and can't exactly find anyone who has had my problem. I'll explain. Wife was playing on our PS3, was done and switch sources and the TV shut off. I came home, unplugged it, waited an hour and plugged it back in. When I did just clicked 3 or 4 times. The red led light would blink a bunch, but the TV would not turn on by using the remote or the controls on the TV itself. I do not even believe it was in a stable standby mode. So I figured it was probably a power supply as this had happened to a friends tv. So I replaced the entire power supply. It however did not fix my issue. It remains the same. So I tried unplugging the Y main, plugged it in and I only got the one click this time, but the red led light does not stay illuminated just blinks. The tv will not turn on, no grey. Just black. The same result came after I tried unplugging the X main. Any suggestions? Honestly my next idea would've have been to replace the main board. However, I know very little about this so I'm leaving my self at the mercy of the gods as it were.

I have the same problem. Even that the caps looked all ok, I replaced 3 caps and still the problem was there. 6-7 clicks, black screen and the red lid blinks.
I replaced the power supply board. Still the same problem. I don't know what else may be the problem. How do we find out what the problem may be?

Thanks.
