Hi Guys Its been a while since i have been on here and even picked up my marker. I have just changed the battery in the handle and charged the marker to fire a few rounds in the garden but my problem is the marker display is stuck on the Nexus logo and wont fire, having been around 3 years since i picked the marker up last i cant remember what button does what, i have held all of them for a few seconds individual and nothing happens. I havent got a manual as i got the marker 2nd hand I believe its an EGO Nexus London 2.0 Hope one of you can help Cheers in advanse Update I have spoken to PE today and the marker is a 06 Nexus EGO I have taken out the PCB and tried to power up as instructed, at first this wouldnt work so i left the PCB on the radiator shelf. I tried again about 2hours later and it worked fine, fitted back in marker and fired a few rounds then turned off the marker and put on the sofa Now it has just powered up on its own???? would you guys suspect i need a new PCB (if i can find one?
