Touch screen not turning on.c4 grand picasso 2017

Hello

Bk in Dec 25 my touch screen decided it wanted to give up. While driving it frozen did a restart back to normal this as happened a few a year. Then 2 min later frozen then reset again this happen for the reset on the 20 Min journey. Next time I went out same thing happened but after about the 3rd reset the screen wouldn't come bk on. You could see it was trying but the screen flickering. Then blue screen sorry can't recall the message. After a few week of this now it's just black screen a few attempts then a parking sensor unavailable message. So replaced the battery after reading about issue may be cause by the battery. Replaced battery on Sunday Monday morning after a drive unit came on wow couldn't believe it. Soon as I turn engine off didn't come bk on. Few hours later came on again but after I restarted the car later that day stopped working. I've tried a BSI reset not sure if a ecu reset is the same thing but I don't really want a factory reset because it will set my car to kph not mph with no way of changing it back. I also got the heaters on because I can't switch them off. Winter was fine but as we in spring. If anybody as had this issue with a fix.

Thank you
George

This does sound like your screen is in its final days, they do give in and go blank eventually, especially if they have been used with low voltage supplies. I had the same issues with one of my C5s and eventually I had to replace the screen with one from Romania.

Hi
I did think that but held of picking a new one up in case there was some other issues for it not starting. I'll replace see how that goes hopefully that's the problem

Thanks
