fixing black box LED

So I "upgraded" to LED about 6 months ago with a pair of black box China things. For some reason now the white channel on one of them doesn't want to come on. Are the drivers really that terrible? I opened it up and they have an interesting design with the driver having both a high voltage output and a constant 12V for running accessories (fans). Has anyone ever tried to replace these? I can't seem to find a match online. I know replacing the fixture will set me back ~$80 but if I can find a ballast I would like to fix it. Any recommendations?

The sicker says Excelvan model ZX-55*3W-KTG-Y
I suppose it could be one of the LEDs or one of the numerous solder points, I didn't open the array panel.
