Hi,
I have a Asus PB287Q monitor and when you turn it on it flashes brightly for a split-second, then only lights up the bottom quarter of the LED strip. When filming in high-speed mode on my phone it seems like all the LEDs do light up for a split second, except for two (see screen grabs attached). One of which pings on as a very last step. Slow-mo vid:

- Try to replace the OZ9998MGN LED controller (it was €1 to buy and should be here in a day or two). I don't have a good justification why I think that might be the issue, I just saw it would be cheap to replace.
- Grab a replacement power board off eBay when one comes up
- Keep poking bits with my multimeter pretending I know what I'm doing
- Something else
Cheers!
