settings are all gd, same as when i got it and correct according to the manual
also any chance it could be the membrane? as well the eyes make the blue boot menu come up and then the red coems on then it turns off, and in the manual it says if the marker doesnt turn on and cycles through the boot up sequence it means the membrane needs chaning.
i know its not cycling through the boot sequence but it does it once and turns off.
(also not battery as i have bought 3 new and none make a difference)
