Have a 4x288 quantum boards in a 4x4 tent. Today when switched on, 2 of them went blank and they don't work now. What are the chances and reason for 2 of them going at the same time?
 
Two pics

If they're running on the same driver and I'm assuming it's an HLG driver? You can rule it out as the issue. All boards would be out if it was the driver.
I can't see two boards just burning out like that at the same time. So it has to be an issue with your wiring. Make sure everything is plugged in and connected properly between the driver and the boards. It's hard to diagnose accurately what your issue could without knowing exactly how its wired.
This is what I do for a living.
 
This is how it is wired in the picture. The connection in the second pic, was disconected for a couple of weeks, because the other light was used. I've reconnected it before the lights were switched on and two boards died. Other wiring wasn't touched. Is it that easy to burn these boards? Any way to check if they are dead completely before I buy new ones?

I'd try re wiring them, check the wires, be sure no breaks

Pull them outa the bds, and re isnert them

Try something


All mine are diy bds so pretty simple to work on
 
If the whole panel is not on, should be power supply problem or maybe the connection is lose. Usually the chip will not burn out easily, but there also might be a chance that one chip on the board is broken that will leads to the whole panel doesn't work. Anyway, just a few suggestion you can check with the light. Hopefully will be helpful. :Namaste:

I took one panel off, which was not working and connected it on its own to hlg driver and it was working. But as soon as I put it back on, it doesn't work. Tried to connect using new wires, still no luck. What could be the issue?
 
They are either in series or parallel connection

I run all mine in series

Re- wire from working bds to none working bds

Easy peasy

Series

Parallel

How would you rewire this? I'll add the pic of board.
