Samsung Ln52a650 Power Supply? not Capacitors.

Question...
Same story, turn it on, it clicks 10+ times then turns on.
I replaced the capacitors on the PB on mine due to all the discussion about bad capacitors. Upon initial inspection, they were not swollen, but replaced them anyway.
So, it is still doing the same thing. I am seeing the power supply board could be bad, so I have no issue replacing it, BUT I really dont want to buy another samsung board and end up replacing it in another 2+ years or so.
Do they make an aftermarket board that would work with the samsung and has the correct capacitors already in place? Spending 150 on a new board then replacing the capacitors seems kind of backwards. thoughts?

Just for discussion

If you google SAMSUNG BAD CAPS you should find the discussion where the debate was if the caps were the wrong values. I agree that the caps were the right values but that's just for discussion.

If you don't want to take a chance it's the wrong board, it's time to let a Samsung tech fix this.

so, its not the power board, BUT I discovered...

I saw where a guy out his samsung tv in a room with a wall heater and it began to work fine. so..I took the back off and used a small ceramic heater. I tried heating the back and not much difference. by accident, I pointed the heater in the area where all the a/v connections go. it is covered with a metal box, but it has holes in it. gave it 2 mins or so and booo yaaa. it came on.
so, tried to find some threads where temp was an issue and didnt see much. I am going to d/l the latest firmware tomorrow, but I am thinking it is some sort of temp sensor that is not working properly. the tv works great when on...so far...
any ideas?
thank you.

That's a FINE CLUE.

Heat not only affects parts but CONNECTIONS. If you are in the tech repair world you know that connection failures account for a high percentage of failures.

Did you use your tech knowledge and unplug, plug in all connectors?

Hmmm...
Not in this particular area, but a good idea. I will take the box off and look over the connections to verify they work correctly or at least plugged in. Give me a few days and see what happens, but Bob, that is a great point. something to be said for forrest and trees.
thank you. be back in touch. jm
