I replaced led strips on this 40" samsung and already i think my worst fears are realized.I think its the panel even though i was super careful and have done this procedure many times before.Is there a sure way to tell?Ribbons look good and flat cables have been cleaned and reinserted various times.

Re: 40" samsungreplaced led strips
It looks like the tab bonding board on the right is not put in place correctly, it is sitting higher than the left side.Never stop learning

Re: 40" samsungreplaced led strips
Hey budm:I have an update.I used my microscope to check connections on the panel and couldn't find a problem with either.So out of curiosity i switched around the ribbon cables and low and behold the problem followed the cable.Its a bn96-24430a.I tried cleaning it to no avail,guess i have order one.Last edited by sputnikoff; 03-05-2019, 05:17 PM.Comment

by KingfreddieOk.. this is the story:
Have an old Samsung LED 3D TV (UE55F6475). First it started to lose light on the lower 40% of the screen now and then. Like for 10-60 mins and then it would work again. Then a bit later it just got stuck in that position. The lower 40% of the screen is dark, and it gets progressively darker the lower u go so it's obviously that LED strips where not working. I also looked for similar errors online and saw an exact copy and on that one it was faulty LED strips.
This is kinda how it looked, just that mine were at the bottom of the screen:

by edugimenoHi There!
I bought a broken 32" TV today. It has sound but no image. I checked with a flashlight and it was missing backlight
Disassembled down to the led strips and found this TV has been serviced before. Not sure if it was fixed, worked again for some time, and broke again, or maybe last repair wasn't successful
Looks like on previous repair, the center LED strip was replaced with a different model, 7 leds in it instead of 8, but when checking LEDS one by one, leds on the center strip were brighter with same test voltage (multimeter in DIODE mode) so maybe the... -
by eccerr0rI suspect a lot of you have done a lot of repairs and end up with a lot of bad LED strips...what do you do with them?
Wonder if I should get a pile of LED chips and try to replace the bad units for the heck of it, but I don't really need the strips at the moment because I bought the strips...
Oh... and I think I got my TV working again, though not 100% I don't think, on a white screen I can see a bit of the ghost of the LED strips, must have done something wrong or the LED strips aren't quite the same as the original... -
by h4rdw4reHi guys,
I have one very old TV.
Main problem I have with this tv is that led strips won't light.
I measured voltage levels, and inverter input is 24V.
other voltages are also ok.
What I found is that removing and connecting again connector CN1 led strips lights for shorts time (but only once). When led strips lights up then light is uniformly spread on whole panel.
First I thought that led strips are dead, but I'm quite sure that problem is not strips related.
I don't know what voltage level is at output of inverter board (samsung SSL400_3E2A) and how... -
by mc900fthannaSo... I have the patchy back light issue with my Visio M70, meaning some light up, others do not. I finally got around to testing the LED driver board and found that was not the issue (swapped another one in and the same issue persisted) and I am considering if i dare dive deeper into this TV and go after the LED strips.
Right away i see that they don't seem to stock them anywhere out there (E700DLB0016-002) is a part number that i see a you tube / seller guy list out. He has a nice video of how to get into my exact TV out there: https://www.youtube.com/watch?v=0AcUPiN83Tg
