Half the LEDs Out on One of my Blackstar 240 Flower Panels

I then sold 4 of them and the people I sold those to had two fail. not totally , just dropped some rows.

FYI -- I just had to make the same repair on another of my BS240s. I probably should order some LEDs. I've just been bypassing the one that's out by soddering in a staple, lol.

Two more LEDs went out. My hands are sore from unscrewing and screwing 128 screws, lol. I really do need to order some replacement LEDs.

If this helps. I've noticed aliexpress/alibaba sells 240w blackstars with a 3 year warranty. And it clearly states 3 year warranty with and no shipping cost for returns on defective lights and they also will ship parts and instructions on repairs. Although the thought of doing repairs on my own seems a little mechanical. Hope it helps. They have really good -prices with free shipping especially if you keep an eye out for the promotions.
