Re: Samsung UN40F6300AF TV No Picture, Sound is working
Thanks for the tip. I'll do some searches and see if I can come up with something. The folks at shopjimmy said they don't carry the distribution strip and said it could be hard to find.
Agian, I appreciate the help....

Thank you! I did find the LED strips on aliexpress. I am working with shopjimmy to see if they have the LED Interface strip. Thanks for the confirmation that it's OK to test with power, since I don't have an LED tester.
This site is awesome....Leave a comment:

Re: Samsung UN40F6300AF TV No Picture, Sound is working
Thanks so much for the reply. No, I don't have those on the LED strips. No BNxx numbers at all. I searched online with these codes that are on the strip and I found it on aliexpress.com:
2013SVS40F L 8 Rev1.9 130212 (left side)
2013SVS40F R 5 8 Rev1.9 130212 (right side).
The power strip (LED Interface SF) has number BN96-25336A. It has been a little harder to find a replacement for this....Leave a comment:

Ok. What about the part number for the LED strips? I wasn't sure which set of numbers were actually the part number.
One other question, once I get the LED strips replaced, what is the best way to test them prior to putting the tv back together? Is it advisable to hook up the tv to power with it being apart?...Leave a comment:

Re: Samsung UN40F6300AF TV No Picture, Sound is working
I manged to get the TV apart and quickly discovered where the problem was. The first led light on the first strip burned out badly and actually fried the strip. It looks like it also may have damaged the strip that supplies power to the LED strips. Can someone tell me which set of numbers on the LED strips is the part number that I can use when ordering a set?
I think I should also order the strip that supplies power, and can I assume this is the part number - BN96-25336A?

Thanks for your reply. So backlights seem to be the problem here. I'll dismantle the tv to get to them. Can the light strips be tested individually to determine which one is bad?...Leave a comment:

Re: Samsung UN40F6300AF TV No Picture, Sound is working
I unplugged the cable between the boards, and the backlights did not come on. Sounds like they are bad. Can you replace individual light strips or should I get a full set for the tv? Thanks....Leave a comment:

Thanks for the quick response! This may be a stupid question, but I only can access 7 of the 14 pins of the connector that bridges from the power board to the main board. Short of turning the board over, not sure how to do that. I included a pic. Thanks....Leave a comment:

Samsung UN40F6300AF TV No Picture, Sound is working
Hello! I have a Samsung UN40F6300AF LED TV that does not have a picture but does have sound. I do see the picture when I use a flashlight against the screen. From the web info I've read, I believe it is a backlight issue with either the power board (BN44-00645D) or possibly a bad LED light.
I'm not sure how to determine where the issue lies. I visually inspected the power board and don't see an issue. I tested the CNL802 LED outputs with the LEDs plugged in and unplugged, and show them below. I tested with a multimeter with the neg lead on the TV chassis and pos lead on the PIN... -
