How will these be repaired? I’d just ask them for a replacement board.

I talked to a local computer repair shop and they said they could solder the diodes. its possible to do that type of soldering by hand right?

ive discovered that leds 1 and 2 in the series are faulty, if I bridge over them the rest of the series lights up. meijiu is going to pay for replacement leds and repairs. meijiu is telling me that the leds they used on my board are AZ V4 S6. now I understand that this means the the flux bin was S6 ...

so I bought a 800 board from meijiu with a meanwell hlg-320h-48b driver and it appears that the light was damaged during shipping. one of the rows doesn't light up when turned on. im new to electrical type stuff but I am a quick learner. I have a multimeter. I believe the board is 50 series of 16 LE...
