I bought my DIY PRO Indoor Monitor (Pre-Soldered Kit Verson) a couple of month ago and just recently put it together. It worked great, but after 1 week it suddenly started making a really loud, constant noise while running. When it starts up it gets even louder for a couple of seconds, before it continues with the loud, constant noise.
I didn’t reflash yet, maybe that will help.
Anyone else having this problem? Or even better a solution^ ^
