Thanks, folks! This was more helpful than you know. I just scored this exact model "broken" TV for $30. I already suspected a bad backlight, since it powers up normally and produces sound, and that's exactly what the problem is. This video will help avoid making any big mistakes when I order the replacement backlight. Cheers!
Yes, thank you, you're definitely right. I've done a few screen replacements before, and haven't screwed anything up yet... but this will be the biggest one yet, and the only one I'm keeping for myself!
The backlight replacement went well! I had to refer back to your video to see if you had to deal with a damaged edge of your fresnel lens. You did, but mine was way worse. I had to dig out burnt bits and sand it smooth. It was partially cracked from the heat, too, so I have a bright spot near the bottom of the TV. No big deal, really. Thanks again!
@@djdrocco common issue the burned reflective plastiglass by the leds and i do the same cleaning it and shold works right. But not perfect. Sometimes may have a big cracks that time will needs a replacement glass
sosfix thanks for the video,the strip backlight are easier to replace than the one you just replace,i`m in norway where are you living?(country).i like the way you`re teaching your son he will be a good technician when he grows up
Great informative video! I have the same tv but a 65" un65nu7100, when you plug it in, the "Samsung splash screen" shows, then the screen goes black for 4 or 5 seconds(off), then the screen lights up but black, no sound, no picture, and stays that way until i unplug it. Im not sure, but i feel that the leds are fine given the splash screen is clear and working fine, but im not a expert. Any suggestions would be greatly appreciated, as i like working on things, and dont really want to buy a new tv.
The screen goes off because maybe some LED is burned, so to protect all the panel the system shutdown all the panel ... But it's produced by a LED damage in the panel .. did you find the solution?
Hey did you have to remove those metal wires on the sides and top? I don't think you did and I can't see any purpose for them but saw them do it on the shopjimmy video.Just trying to figure out if I even need to waste my time pulling those
Hello, did you measure the volts on the LED power supply output, that 2 wires going on LED strips? I get 200 VDC from both on output, dunno if that's right, sounds a bit too much to me.
Be careful when doing this. i just attempted it and the glass broke in the process. be very careful with the glas panel and LCD panel. Its a 2 man job for sure, dont try it alone like i did. But besides that it did work, but now i have a broken lcd unfortunately
I have this same model tv.. samsung 55 led.. the tv cuts on and off with a flashing standby light.i hear a start up sound and see a blue screen when this happens.. when I disconnect the main board from the power board the backlight alluminates.. any suggestion what may be the problem?
sounds like power board + backlight are good, your problem between mainboard and screen ( no tcon in this model) try to cover some traces on the flex cables thats going to the screen, see if you get some lines or even some picture, i think i faced some of these series with faulty sceen
After seeing you and your kid fixing or taking the tv apart, it encourages me to do it. Thanks in advance bro!
You can do it!
Very cool guys open up a service .. for tvs not many places for TV repair these days ..
Thanks a lot for you and all the other youtubers. I managed to watch these videos and fix my TV for just 1/10th of the repair cost.

the led output voltage should be marked on the power board

Bonjour j'ai le même téléviseur ou trouvé ces deux barres led merci

Hi! Was there only 2 total led strips?
yes this model has only 2 led strips in the bottom
@@SOSfixElectronics just to confirm you only need 2 led strips for the 55nu7100?
well my LCD panel decided to crack time to trash that tv and never buy samsung again but the backlight replacement worked >_>
sorry, the screen is very fragile
Backlight can go bad on any brand, it's a matter of if you keep the backlight in settings on 100%
Hi, can I know the LED strip size(cm)?
sorry i dont know
Wtf this looks tedious as hell, whats with the fast forward portion, I have no idea what is being done and why. I have lost interest in fixing my tv.
