Replacing a Samsung LN40B610A5F LCD TV Fluorescent Lamp Assembly

This video outlines the replacement process for a Samsung LN40B610A5F LCD TV CCFL (Cold Cathode Fluorescent Lamp) Assembly. I created this video to assist others as I found little information about this process at the time I was troubleshooting this TV’s problem. Sorry it’s lengthy but hey it’s a kinda big job. If you choose to do this, be wise, take your time and don’t hurt yourself. There are almost 30 sections or chapters, eek. The verbosity will be appreciated by the newbie I am sure.

Comments/Questions and constructive criticisms are always welcome. Idiotic comments will be ignored. Don’t feed the trolls.

Here’s the start time of the major sections;

    Hi…there is anyway to know what kind of lamp i need for my lcd (marantz 32) ?
    Its flickering and when i opened it up there was dust. I have cleaned it but nothing changed so i think its the backlight

    Awesome job. Feels good to fix things that other people won't take the time to do. I have 2 of the Samsung LCDs with the big push button in the middle that had bad capacitors in them and they both still work great,. I gave one to my ex and have been using the other in my bedroom. The picture quality on the new LEDs is not even close to the old school Samsungs. I wish there was an easy way to convert the CCFLs to LEDs because that thing is like an oven.

    You're the first to show how to change Lcd lamps. Maybe the other people are to stupid to know how to fix that on a LCD. I wonder can you get them new ? Thanks for the video you're ahead of the other TV men.

    Great video man! I really enjoy seeing people bring old electronics back for a second life

    I found one exactly like this in the trash today. I took it apart. Looked old. Its not working. Fuse is good. Capacitors are ok too. Won't light up. Is there anything I can make with the parts ?

    Hi Steve
    First, I must ask you to excuse my English.
    I have saved a lot Cold Cathode Fluorescent Lamp from a Samsung TV and had in mind and use them as backlight elsewhere than in a TV.
    For example a bookcase, under a bar or decorating a dressing table – yes the ideas are numerous. But I lack some technical specifications of the "Fluorescent Lamps" as how much power they use (Volt) and so on … Can you help with such information?

    Thanks in advance,
    Best regards Morten,
    from Denmark

    Thanks for the video Steve. Great job getting it going again and keeping it out of landfill.Cold Cathode Fluorescent Lamps contrary to their name are not "Cold". Burning at the ends of the tubes is caused by arcing or spluttering as the tubes age. The inverter board is shutting down because it is sensing a over current fault because one or two of the tubes have a arc track causing high resistance. The old CCFL's were run at maximum brightness causing them to age far quicker than they should of. When people buy a new LCD-TV (whether it be L.E.D. or CCFL backlight have the same problem) they will plug the unit in setup the channels and leave it at the factory default settings. These settings are always set at maximum backlight brightness causing their $2k plus LCD-TV to die sooner than it should. The manufacturer's always give the maximum power consumption IE: 250watts because that's the max power the set will pull from your house AC supply. Lowering the brightness of you're TV from 100% to 50% (I have a 52 inch LG TV and it only pulls 120 watts at 45% brightness) will not only save power it will save the TV set from self destruction. I been fixing these rubbish TV's for some time now and I am just starting to see more L.E.D. backlight TV's coming in with blown LED's in them causing dark spots in the panels. For your own sake turn the brightness of the backlight down as low as you can and save yourself loads of money by not having to replace you're new TV at 2 or 3 years old and not having to pay all that money running a 250watt TV at maximum and run it at 40% brightness and running at 120watts. Makes sense I should think!
