What is the tv doing now if anything ?
Is there a light or blinking light at the front , clicking sound from inside when you plug in the power cord or try to turn it on ?
Or completely dead no activity whatsoever ?

Light on in front. No clicking. Responds to remote the light that is. No sound. Have back open have been trying to tech out which board is bad
Customer reply replied 1 year ago
Control board has a 5 second on 2 second off pattern.
Customer reply replied 1 year ago
Unplugged each board and restarted tv with no response. Single click on ps when turned on as normal. Used multimeter to check voltage pins for ps. Seem to match what listed on the board
TV Technician: Jack, Technician replied 1 year ago

No schematic , nor service manual nor any help of any kind from Samsung on those TV's so you have to break out the multimeter and troubleshoot with experience

What are you saying exactly.

Do you have a voltmeter and more to the point , do you know how to use it ?

TV Technician: Jack, Technician replied 1 year ago

If you have no voltage or worse low voltage there when you press the power button then your $24 power board is defective , here is where you can get it ;http://www.shopjimmy.com/samsung-bn44-00511a-power-supply-unit.htm

Ordered the part. No way of knowing anything until it comes in. Will happily rate as excellent then. Thank you.
TV Technician: Jack, Technician replied 1 year ago

Your power board has low voltage , that tells me it is defective .

If it had zero voltage there i would`ve said then perhaps it is not being switched on but now it is and does not supply its voltage .
