I had to replace the blown power supply in our Centroid M400S
controller console.
But now the LCD screen not coming on.
i hooked up an external LCD monitor to the video out put of the mother
board inside the console and that works.
So I assume internal LCD is not getting power or some thing got blown
in the LCD!
Any idea?
Thank you!

Here is a bunch of links on what is involved in finding and fitting a
replacement LCD.

What I read, if the LCD screen goes out so suddenly, means the
inverter, supplying high voltage to the back light lamps, broke.
Needs to be replaced.

You then need to determine which is easier/cheaper to get, an
individual part for a specific screen, possibly marked up 4,000% by an
MTB, or a generically available LCD screen.

One thing I don't know, where the screen/display get's the power?
From the power supply of the mother board or the main box mounted on
the mill?
Home PC's display has a separate 110V !
