Re: Samsung LED tv UN46C8000 no picture
I measured its resistance and it showed 1.9 kOhm.
Sorry, for confusion, the element actually is labelled as D116 not B116.
Thanks.

Re: Samsung LED tv UN46C8000 no picture
Today, I measured voltage on the black element labeled B116 next to F2 fuse on t-con(2nd brd). On its top, voltage was 12.5V on the bottom only 1.5mV.
Any idea what this element is for?
Thanks,

I do not see anything labeled with F on the main board (3rd pic). I see a lot of small parts which looks like a fuse but they are labeled with C.
Thanks,

Re: Samsung LED tv UN46C8000 no picture
Hello,
I have a digital multimeter, that can measure everything. I measured smd fuse resistance on psb and t-con a (1st nd and 2nd brds), with tv turned off. All of them showed 0 ohm. I also measured capacitance on psb(1st brd) of big black capacitors. Multimeter showed 0, 3 and then 83 mF on all of them, although I see 12mF is written on them.
Thanks.

retiredcaps,
I am not sure what are smd fuses? I located F1 and F2 fuses on the top of tcon board(2nd pic) and measured voltage on both ends. Both voltages were the same.
tom66,
When I connect to dvd player I have clear sound, but with tv channels no sound.
Appreciate any help on figuring out this issue.
Thanks.

Correction to the original post:I was unable must be read as I was able.
Here are pictures of three boards.
Thanks.

Hi PlainBill,
Thank you for your response. I do not see any violation of posting rules. There were posts on the same problem but for different models. This model's t-con and pcb look completely different that is why I did it as a different post.
Could you please let me know how can I figure out which board has a problem?
Thanks in advance.

Samsung LED tv UN46C8000 no picture
Hello,
I have bought Samsung LED tv UN46C8000 about 1.5 years ago. No picture, but sound problem. Menu also does not show up.
I have checked there is back light.
I read in this forum that a capacitor or fuse must be replaced for a different model. I took a look to capacitors, they look OK. None of them has a blown top. I was unable to locate a few fuses, measured voltage by millimeter, they also look fine.
Any ideas how to fix this problem?
Thanks.
