    just run the power supply board in self test mode by do not have the cable between the power supply and the main board connected to test the backlights. You should invest in LED tester.

      Re: Samsung 60" LED blank screen and WILL NOT STAY OFF

      Well I pulled the panel back apart and tested each strip with a series of (5) 9v batteries... Turns out the old strip I put in to replace the charred one was actually good. The strip above it however, only one half works. So not only did the connector fry on one strip, but ANOTHER strip has a burnt LED now (the very first in sequence because the other 6 won't light, but the connecting 7 light up fine). I already contacted Shopjimmy a week ago and all they could offer me was $20 store credit. I understand that I'm far out of warranty, but not only do I have catastrophic manufacturing defect, but also a premature failure of another strand. With the amount they charge for a replacement set, they should far exceed "180 days". This is bullshit. I'm emailing them again and demanding a replacement set.

        Also tell them that there are lots of people on BADCAPS that see the failure, it will make shopjjimmy look really bad.

          I already sent it, but I was sure to include that if they don't replace them I will not purchase not ever recommend them in the future. If they don't succumb to my email, I will certainly follow up with what you said.


          Side note, as evidence, I've stiched together another working strip of the factory Backlights and with the PSU in self test mode, every single one is lit.

            I'm not buying any backlights from them, pretty sure they get theirs from china anyway so you can get m directly from allied for much cheaper.

              They have yet to email me back. At this point I think they are just ignoring me. I wanted to share my "Success Story" on the product page, but I read the process and they literally review your story before they'll post it. That way they don't get negative comments or reviews.

              I'm reluctantly going to reassemble with two strips of the OEM lights. Having a 60" panel lying on the floor makes me so nervous it's crazy, and I'm not waiting until I can afford new lights. I don't know how long the originals will last me, but I'm going to find out. I'll definitely turn the backlight down to about 60% though (usually keep it at 70).

              Side note, I found a complete set of brand new backlights on eBay for just under $55 shipped. It's a different brand though (Beented?). It's still nearly $40 less than the crap Shopjimmy has.

                Well if it's your own tv, I'd go with the lowest backlight setting you can tolerate, they might last quite a while, it's when they are maxed that they burn out pretty quickly and if one burns out you already know the drill.

                  Would it be true to say that they're similar to car parts? If one tie rod goes out, the other side isn't far behind because they've been through the same use and abuse?

                  I know LEDs are supposed to have an incredibly long lifetime, but it just seems that isn't even remotely true in TVs.

                    I wouldn't be surprised if they fail, They are overdriven, probably on purpose so they can sell more tvs, some peeps do a resistor mod to bring down the current, some tvs also have backlight settings in the service menu, some tvs not all of course as soon as you change a certain setting in regular menu, they jump up to vivid again which is max.

                      After revisiting the menu I found that the Backlight is 1-20 not 1-10 as I was previously thinking. I actually had it set at 12, so I've been running them at about 55%.

                      Also, results

                          Thanks! Would you know I've taken the panel apart 4 times in the last 3 years?!

                          Thanks to you, budm, and everyone else who helped me diagnose and fix it as well as my Hisense in another thread, which is still working great after hours of N64 use!

                            Good work, we have broken quite a few panels around here/the forums, they are so damn flimsy and delicate.

                              I'm embarrassed to say, but while on my knees reattaching the frame the previous time, I lost balance and actually rolled over onto the panel! Miraculously it did not crack! I did however have it placed onto a 3/4" comforter on the floor. Regardless, it goes against all odds that it survived, but you can only imagine my gratitude.
