Power issue

Hi,

I'm getting "power issue detected". But I cant where the problem goes from. Is it possible to read how low exactly power voltage was?
My setup is wanhao d7 with stock lcd and lcd driver, stock motherboard and rpi3b+. StockPSU(12V 6A) powering motherboad. Dedicated DC-DC (12 to 5V, 5A)  converter powers rpi and LCD driver.Whenever I'm getting power issue message, LCD dricer losts HDMI connection with rpi. Happens quite randomly. Half a day yesterday everything was fine, this morning got message nearly right after power up.

Re: Power issue

It is Pi's internal mechanism detecting low power. You can use linux dmesg to find out exact time it happens, but it is not possible to know how low it goes.
