    Sharp led strips

    I have a new to me sharp 70in that I replaced main board on it and picture looks great. When I first turn it on and the screen is black with just backlight on I see about 6 leds that have more of a spot light effect. I think the pic looks fine but wanted to order some strips for future use. Is there anyway to find out what part number strips are in it without disassembly? Thanks Michael

    You didn't include model number, a quick guess would be if it's a led backlit tv, maybe some of the lenses have fallen off and need to be glued back on. If that is the case observe how the others are positioned and glue them back on in the same position.

        Boy that bites, it's already mounted above the fire place. I wonder if Sharp would tell me part number by tv model. I didn't hear anything moving around in there while working on it. I will try to get a pic tomorrow and post.

          It doesn't take much to get the halo/spotlight effect, just a small misalignment, had a good thread on it not long ago, see if I can find it.

              Look like these don't have the normal round lens.

                According to the manual this panel uses 3 backlight strips along the bottom of the panel, any light spots around the edge is likely the lcd panel at fault

                  LED problem on samsung UE55F6475, 2 strips work. The rest is flashing every second.
                  by Kingfreddie
                  Ok.. this is the story:
                  Have an old Samsung LED 3D TV (UE55F6475). First it started to lose light on the lower 40% of the screen now and then. Like for 10-60 mins and then it would work again. Then a bit later it just got stuck in that position. The lower 40% of the screen is dark, and it gets progressively darker the lower u go so it's obviously that LED strips where not working. I also looked for similar errors online and saw an exact copy and on that one it was faulty LED strips.

                  This is kinda how it looked, just that mine were at the bottom of the screen:

                  by edugimeno
                  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?
                  by eccerr0r
                  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...

                  Grundig 40VLE7131BF led strips doesn't light up
                  by h4rdw4re
                  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...

                  Driving a Sharp TCON/panel with a universal main board
                  by advant
                  This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.

                  I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...
