MP201 Hard Reset?
Posted: Fri Jul 24, 2020 11:48 am
A few months back my MP201 just stopped working.
It turns on, the screen lights up and the LED rings around the buttons light up at random.
However nothing shows up on the screen?
I tried turning it on while holding down various buttons. It not being uncommon for this to be a method of accessing boot modes like hard reset/firmware update etc on other devices I own.
All this gained me was getting different LED ring colors.
Opened it up and tested from the well marked, convenient test points.
5v and 8v both read 5V and 8V pretty consistently.
The sensor test point reads 0.225 to 5V pretty consistently.
(probably needs calibration).
So it seems fine, just maybe needing a reset? Either that or the microcontroller is fried somehow, but everything else is good?
