    As long as the diameter is the same you can make them work,I have used them.
    Still Email them and see if they have the double ones.i would think they would.

    All 4, i looked today in the daylight and saw that the other 2 are a bit black at the ends, so to hell with them. I dont want to have the same work in 2weeks, just because i want save a few bucks now.
    I think the problem with the universal ones is, that they dont fit. I need a double rubber and i didnt saw any on the internet.

    ^ I thought of them later last night.
    I would Email them and Ask about the silicone end caps,If you can't get exact replacements they do make universal ones.
    Were you able to test your other CCFLs,Or are you going to replace all 4?

    ok, i just found these here: http://cgi.ebay.de/2-4-x-420mm-Full-...item3a585acf88 These should fit and got even a fair price.

    Strange thing ccflwarehouse.com is delivering over ebay worldwide.

    I got one last problem, where i can buy these ccfl rubber things? 2 of 4 are burned in the panel... (see pics above)

    ^ If you’re able to use ccflwarehouse’s 800 telephone number call them and ask them those questions
    They are very courteous and helpful.
    The last time I checked they were offering 4 CCFLs for $30 and about $5 shipping. That would probably be your best bet

    Re: Burned Backlight - Samsung 943NW

    how do i find out, which color temp. and thickness they have?
    The new lights should just have the same thickness and length. Or are there some other things i should have an eye on? I dont want to buy something and then put it in the trash, because it doesnt fit....

    I would say you could get by replacing 2 CCFLs.
    You could be sure if you had another panel by plugging in 2 CCFLs from the other panel, and see if the lamps stay on.
    I would also suggest ordering some new silicone end caps, some members have used RTV silicone I find that rather messy and then I have to wait for it to set up.

    Edit
    I would say for sure test with 2 other good CCFLs to make sure the others are OK

    I have big dogs also, I am getting pretty good at lightly brushing things off with a soft cloth and quickly assembling before things get back on it.

    There are some pics of similar screens on the net, but no one is showing how to get to the ccfl's. ( like this: http://s807.photobucket.com/albums/y...t=DSC01173.jpg (not my photos))
    I am sure there pictures or video out there some ware. But it's really self explanatory.
    There is a sturdy metal frame around the lcd, The thin LDC panel is next. There is a black plastic frame that keeps all the diffusers in place. There is a very thick piece of plastic in the metal framework that the CCFL channels slide over. Just go slow and don't force anything, keep everything in order as you disassemble. I think dust and stray hairs are going to be your biggest problem.
    There are some panels that the CCFL channels simply slide out.
    If you could find a LCD with a damaged or broken panel it would give you an idea what you need to do.
    Most of the newer LCD are all alike And you are going to be surprised how easy it is

    Samsung QE82Q70RAT no backlight
    by sansanpartida
    Hi everyone!

    Hope you're all having a great day, and thank you very much for stopping by and taking the time to read this post to help me with my parents' Samsung TV.

    My issue: No backlight.

    Model: QE82Q70RAT
    Type No: QE82Q70RAT

    The TV was already serviced by Samsung once under warranty for the exact same issue, but six months after the fix, the backlight went out again. Now, Samsung is asking for nearly the same price as a brand new TV to fix this with the same 6-month guarantee.

    So hopefully, I can fix this cheaper.

    Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
    by Ierwin
    Hello everyone,
    Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
    The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
    He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
    I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
    Anyway I still fully expect that there has been something seriously damaged...

    by Max514
    Hi all,

    Ok so I have this beautiful un55h8000 samsung tv with sound but no video nor backlight. When turning the set on the red light blinks 5 times.

    The screen shows no damage and backlight turns on when I disconnect the power supply from the main board. The tcon board only has 2 out of 3 leds on.

    I came across this page and followed the different steps: https://techhometravel.com/samsung-u...ight-no-video/
