    Lg 55la7900-ua

    Good day guys

    I got this 55" LG TV from a friend. The TV functionally works as it should, but for the two vertical darker bands on the display. I've read a lot off threads, and it seems as if it might be the panel. The bands are consistent, even when the backlights are turned down to around 10%.

    Thanks for any help. On the second photo the backlights are turned down to 10%. 3D is turned OFF

    I would suspect there are a few led's that are bad on the strips along the bottom in the panel. Shopjimmy lists the strips (2) for $54.95

        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:

        Backlight strip quality, Amazon vs Ebay vs ShopJimmy. Is there really a difference?
        by DXseekerMO
        Hello everyone!

        Recently I've noticed that some ShopJimmy backlight strips don't have double-sided tape installed upon them when an application calls for it, and I must purchase the tape separately. In a recent chat conversation with a customer service agent I told them if this tape wasn't applied when it was called for I would begin to consider ordering my backlight strips elsewhere. It looks like this time may have come.

        I recently got a TCL 65S4 with bad backlights. After looking at the SJ listing here: https://www.shopjimmy.com/tcl-jl-d65...365as-m-led-ba...

        Samsung UE48H6410 replaced Mainboard but backlights doesnt go on
        by max789
        Hello, I have a problem with my Samsung UE48H6410SSXZG with the main board BN41-02156A and the power board BN44-00709A. Everything seemed like this, the TV could no longer be switched on, the standby LED always flashed 5x2 times. Backlight was off and no sound from TV. Also made the flashlight test and there was no picture.

        I made the following tests:
        1. Disconnected the main board from Power Board = backlight works.
        2. Connected the main board and disconnected the T-Con = backlights does not work.

        So I ordered a main board from Ebay also BN41-02156A but from...

        RCA RLDED 4331B: 43 inch LED TV: Backlight issue
        by lmcancu
        Hi I am having an issue with the LED backlight of this TV. I can see the picture with a flash light, so I determined it was a backlight issue.

        Initially, after opening it I found 2 shorted and 1 open LED on 2 strips (total of 4). I removed the LEDs and shorted the pads together to verify if the backlight would work.

        Testing it, I found the backlight turned on and I measured 54V when TV was in standby (off), and 100v when TV was turned on. The 4 strips each contain 9 LEDs, so 36 in all minus 3.

        Instead of putting it back together I decided to replace...

        Help findinf LED strips for TDSystems K32DLT1H
        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...
