LG 32LN5400 TV: Seeking Suitable Replacement for Burnt Backlight Diodes

Hello,
I have a question about the LEDs used in this TV 32ln5400. There are two strips - upper and lower - marked 6916L-1437A B2 and one strip 6916L-1438A B1. In my TV there were two LEDs at the bottom or B2 and one LED on the B1 strip.
When connecting the 18V power supply to check the LED strips, it turned out that the B1 strip is much darker than the B2 strips. I want to choose diodes that would match the current parameters as much as possible. I need to buy two types of diodes or can one solder be similar to both tapes? I found such LEDs like the TV LG 2835 model name LATWT470RELZK LED, but will they be good?
parameters:
SIZE: 3.5 * 2.8 * 0.65 MM
1 W led Cold Whtie
CAT: 110-140lm
CCT: 7000-10000 k
REF: 3.0-3.6 V
I (MA): 350ma-700ma

I can't find the parameters of the original diode from the B1 and B2 strips anywhere, so if someone has encountered this problem and solved it please help with what diode parameters to look for
greetings

Both slats available new at a reasonable price .... Why combine ...
And even the LEDs themselves are available ....
ps. the diodes have the same ...

Probably this middle strip barely glowed because of this one damaged diode. Thanks for the info that they are the same, I have already learned something. And it combines so because I have still peeled off one matrix tape next to the disc and I will still play with it and it can easily go something wrong. That's why I'm looking for LEDs for soldering and testing. It turns out that the diodes from the TV have dimensions of 2.8 x 3.5 - the same as I found in the first post. Only will the light intensity match in both cases?

18V you won't check the belts ...
Buy a whole new strip and you are sure that it will be ok, and so without checking each diode separately you will not know if in a moment you will not disassemble the TV again.
LEDs do not know what intensity ... or rather how many k.

I checked the strips with an 18V power supply. The first from above shone strongly and all the LEDs. In the middle bar, the LEDs lit up very weakly, including one for replacement. The bottom bar was shining strongly apart from the two diodes that are to be replaced. I will order LEDs 2835 solder and I will know if the original ones also have around 110 - 140 lumens. Unless someone knows the symbol of the diode that best fits or the original data?
PS I do not want to buy two new slats. I want to choose the most suitable LEDs, solder them and see how long it will be ...

Hello, I will stick to the topic, Reptajl - did you fix the TV, what strips did you use? .
original strips are marked:

while I found replacements marked:

32 '' ROW2.1 Rev 0.9 1 A1-Type 6916L-1204A

but I don't know if they will fit.

Hi. I ordered LEDs from Ali, but they are still on their way. On days should arrive. When I solder them, I will write what effects.
Greetings

The LEDs came, soldered in. One strip shines well and the other diodes barely glowed after soldering a non-illuminating diode there was no improvement. It probably broke the circuit somewhere. I dragged the cables to the diodes to check if the backlight would move and all the strips lit up well. Anyway, I have the matrix tape removed and I won't be able to do it anymore. The LEDs I used have the designation 2835. Solder should be done sensitively because they are extremely delicate and like to crack.

Or?
Did you damage the matrix?

The matrix is whole. One tape is peeled off and vertical stripes appear on the matrix. I wrote about it somehow at the beginning of the topic. That is why I did not buy new LED strips because I wanted to do it at cost if it turned out that I could not cover the topic of the tape. If I find some time I will play with it yet. I've seen some patents on how you can try to connect this tape. After introductory familiarization with the subject, T-Con (among others) may be at fault.

Show photos of this tape damage.

Reptajl - for me, the situation is such that everything is ok, except for these 2 LED strips (there are damaged LEDs of 1 in each strip) I was able to buy strips in the replacement (PLN 22 with delivery for 2 strips), but now the question is what to stick to cases because they are without glue?

I glued with double-sided tape quite strong, cutting the strips under it. Buli1 tomorrow or the day after tomorrow I will take pictures of the detached tape and turned on the TV with these vertical stripes (hard time).

Today, I put on a strip, the TV shines nicely, everything is good, if someone needs a strip, they are on the Internet for PLN 7 per item, it doesn't pay to play soldering.
