8pre ES - Won’t Boot / Might Partially Boot

Post by motupanplayer »

My 8pre ES won’t consistently boot now. Sometimes it will light up all buttons, but no display. Sometimes it will get to the point of showing the MOTU logo in both screens. Sometimes it will go further, but get hung on the animated waves. And then sometimes it will make it through a full boot, but then become unresponsive in a couple of minutes.

I got this in 2020, so it’s well out of warranty. But geez… it’s now - $1100 brick??

Anyone know of a button combo that will reinitialize this device? Or a possible cause? Thanks!

If it is the power supply, MOTU will sell you the part for $30 plus shipping

I have a feeling that’s might be the cause, as it seems to go funky the longer it’s on. So the internal supply is easily replaced?

I bought the supply as a backup, but have not needed it to date, so I can't say I've actually opened up my 828ES or carefully inspected the supply. That said, I'm virtually certain it is a pretty simple, no soldering required, situation.
