Facing TV Problems? Ask a TV Technician.
Hi , I`m Jack , I will be helping you today Can you please send me a reply when you are ready to proceed ?Note that I need time to type and research for parts and info if needed so don't be surprised if there are delays between replies
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 ?
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
Do you have a voltmeter and more to the point , do you know how to use it ?
I`m saying that this will require troubleshooting
give me a few minutes please
Click the link below , that's your power board and look where I pointed ;
The website does not refresh the page , you have to look down to the last line .
That is it ??
Did you see what I wrote on it ?
Yes the TV's chassis is the ground reference
O.k and I assume that is with the tv power ON ?
Sorry bit i did tell you at first it could take time between replies
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

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 .
