SAMSUNG UN50EH5000 dead no power
It looks like it dead when i plug it in no pic no sound no red light on the power button. i checked the outlet, it has power, i checked the power cord on another TV and it worked. I replaced the 3 boards in the TV, the power board, main board, and T con. still no lights anywhere. Any ideas on what it could be? -
Re: Samsung 50 inch LED no picture model UN50EH5000
i removed the connector and put the red probe on each of the 14 pins in there for a reading and using the numbers you mentioned above as the layout.
1 - 12.4
2 - 3.3
4 - 12.4
5 - 12.4
6 - 2.9
Then when i touched 7 there were some very small sparks and now got no reading and when i go back to 1 through 6 they all read zero.Leave a comment:

Re: Samsung 50 inch LED no picture model UN50EH5000
So i got some measurements then reconnected plugged in and get no red light indicator and no response when trying to turn on. see pic it's all connected back the way it was and seems dead. Does this indicate anything? i dont think i broke any parts either. It's almost like i mentioned in my original post. Sometimes it would shut off maybe it comes back on in a second maybe it takes a minute maybe it takes hours. then it will go months without it happening. now it's dead....Leave a comment:

Re: Samsung 50 inch LED no picture model UN50EH5000
below is the voltmeter i have. what setting do i put the dial on?
and when you say on the pin, do you mean the metal pieces that come out the back of the connector and goes down do the board? and i assume the diagram next to it with the 7 boxes shows me which is which right?
Please be specific as to when i should have it plugged in and or turned on/off while doing this. i am a little nervous of sticking metal probes in something that is live with electricity....Leave a comment:

Re: Samsung 50 inch LED no picture model UN50EH5000
nothing happens it's black no back lights and looks pretty much dead when i disconnect 14.
the power button is on the side connected to the main board so by applying power you mean just plugging in?Leave a comment:

Samsung 50 inch LED no picture model UN50EH5000
I have done a little bit of trouble shooting and am hoping someone here can maybe give a diagnosis. I have sound but no picture. In a dark room with a flash light i can faintly see the picture. i have no back lights. The TV has had problems with randomly shutting off. Sometimes it comes right back on, Sometimes it does a few power cycles. Sometimes i can't get it to come back at all and just have to walk away. I don't see any bad caps on any of the boards and no obvious damage to them. Below are the Power board and T Con. Any suggestions are welcome. I'd rather not buy a new TV if i can fix i... -
Re: New Members - please post your introductions here
Hi All,
My name is John and I live in Florida. I am here mostly for help with my Samsung TV. I have 4 of them so i might be here a lot from what i have read in the forum already. I also have 2 PCs that will probably need some help at some point. Don't know much about them, i only keep them around to play Battlefield 1942.
