My PCM just went blank randomly when driving. I was unable to switch it back on.

I tried the obvious turn off the car & back on, tried spare key etc but no success.

I had a look on the 718 forum & tried a tip from there which resolved it straight away.
It was just a case of pushing the volume/power button in for 15 seconds which rebooted the PCM & brought the screen back to life.
Hope this is helpful for others.
