repairing led lights

[beaslbob]

Just had two of four channels fail on a dsuny long skinny no fan led fixture.

Can anyone give my some analysis of how to repair it.

I presume some kind of channel driver burned out. the panel was in a new hood for a week and I presume there was not enough ventalization. It has 11 month in another hood that was higher and the panel sat lower in the hood for more air circulation.

TIA

If you familiat with a olt meter check voltage out of driver to leds. If no voltage coming out make sure voltage is going to driver. If voltage going in but not out its a bad driver
