    LG 60" 3d TV LG60LA6200UA Screws and LED Beads

    What size and head type are these circuit board screws?

    On the LED Strip is :
    SH S1 94V-0 N 1329. LG Innotek POLA2.0 60 Rev 0.1 L Type 2012.10.18

    I want to know what LED Beads to use for replacement and where can I read and learn what size and voltage is correct without relying on an ebay seller
    and where to buy them?

    What is POLA2.0, L Type?

    Most of the clear plastic (I'll call Filter Beads) glued over the LED Beads have fallen off leaving three black dots with clear plastic in them where they broke off. Do New Filter Beads have three feet dots that glue to the black dots or are the black dots part of the clear plastic filter bead? I would think "Distance from the LED Bead matters.
    I measured with my digital caliper I get about 2.8mm X 3.5mm

    I set my meter to diode and get .765 and .764, with leads reversed I get a dimly lit LED.

    Thank You

    If you want your repair to last, I would replace all the LEDs with new strips. The working ones will likely fail in the future since they have wear. There are two styles of the LG thick lens strips. In both, the lenses may also fall off over time and with gravity. Another reason to replace all your strips with new. POLA2.0 style uses a smaller lens in Heesung panels vs the larger lenses in the LB/LF series. L indicates it is a left strip.

    If you don't want to listen to my advice and just replace the LED module, they are likely 2835 1W 3V with small pad negative. Gluing the lens back on has to be aligned precisely or you will get halos or bright spots. Even turning down the backlight after repair, I've had repeat failures if you don't replace with new. If you test every lens, you will likely find many about to drop off.

      I have no idea why you would make a comment "If you don't want to listen to my advice".

      I am here seeking every possible way to replace the LED's and/or the strips.

      I have never done this before but my 3D TV broke, and after watching Youtube Videos from a man in Chicago take apart an LED TV and replace one led bead on a strip, rip the plastic sheet removing it then billing his customers drove me to do it myself and to come here for the best honest advice.

      I bought a complete new LG LED Strip exact set to replace mine.


      "POLA2.0 style uses a smaller lens in Heesung panels vs the larger lenses in the LB/LF series". You lost me with the "Heesung" panels.

      Is a New POLA2.0 style the same as my 2012 POLA2.0? or that POLA2.0 is a newer style than LB/LF? Where can I read and study this topic?

      This is all new to me. Where can I buy Backlight strips, are new better replacement strips available, Who do I trust?

      I was planning on rebuilding the old strips sometime in the future but looking at the lens and the black dots where they were glued on
      would be impossible unless the black dots are removed and new lens installed.

        neilc6 is just attempting to strongly express his view that in his experience, strip replacement is a better longterm repair than individual led replacements.
        Willing to help but I'm no expert.

          What was the point of your remark?

          I received not one part number for LED Beads or Lenses, procedures or any links to learn; just an emotional my way or the highway cognitive distortion.

            I searched "pola2.0 60" on ebay and got lots of matches. I also searched "2835 1W 3V LED" and got lots of matches as well.

            Usually when I recommend full strip replacement, the typical response is why pay that much for strips when LED modules are only a couple of bucks.

              They are called light emitting diodes, often shortened to LEDs.
              If a TV has a burnt out LED you can guarantee that all the other LEDs have been driven just as hard and aren't far away from dying themselves.

              Yes you can replace individual LEDs and the lenses however it's mostly a waste of time as others will die shortly and you have to be exactly precise with the spacing. You can replace individual strips but the others won't be far off from dying.

              Hence why Neil6 strongly suggested to fit all new strips to save you stripping down your TV again which takes time and increases the risk of LCD damage

              There are no part numbers for individual LEDs or their lenses.

                  I'm sorry if you don't understand I was correcting your incorrect terminology and reinforcing the message you're wasting your time just replacing individual LEDs or strips.

                  Most posters on here fix the stuff they are talking about and try to impart their knowledge to help, there's never any need to be rude.

                      this is wrong theory if change individual LEDs on LG Innoteck, will cause later other leds failing, in 2015 i replaced 2 LEDs on 47LA6208 till today the set working.. of course the backlight level brought it down. the questions always from which source you purchased the LED.

                      and what you will do if you changed all strips , and they make light spot because the lumen are higher than Original ... we read this issue over here too.

                        I haven't purchased any LED Beads. I am asking What exact LED Beads to use to replace all the LED's on all the strips. I Never implied replacing one LED Bead.
                        I want Part Numbers or size with mA rating and Voltage. I am not asking How to fix anything.

                            i would warning you too if you are going to replace all LED, you will fail by sitting the Lens. its very hard job... changing one LED you can play with lens but this game if you are going to try it to all LEDs Lenses no joy at all

                                Yes I agree, a very difficult task. I see it on YouTube in very poor countries.

                                  It's difficult, but doable, just need some time and patience.
                                  I also bought similar LB strips on aliexpress which had much warmer white and slight dark spots where the lenses are.

                                        Problem

                                        This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

No bulging caps. TV would start consuming about 7W immediately after plugging it in, but no response from the remote or power button. Thermal showed the main chip on the mobo getting warm and nothing else. Power supply appeared to deliver stable 12V to the mainboard.

                                        I ordered a replacement mobo(actually both mobo and PSU just to be sure) and popped it in. Picture! Sound! Endorphins! Then I noticed three long dark strips. Hmmm, had...

                                        Hi 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...

                                        What to do with bad LED strips?

                                        I 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...

                                        Hi 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...
