ok i'm probably being noobish but i got this in a trade, put fresh battery in (duracell) but screen flicks from 'full' battery to what appears to be a small square with a 'hook' on top , turn on air with no leaks, (dry firing.....) pull trigger and fires with two loud bangs then drops pressure and get 'put-put' noise with bolt staying forward on some occasions (bolt pin is in correctly), leave it for 1-2 seconds then fires in the same cycle as stated above, i havent owned an ego since 05 and recently had a Geo+ with no problems, marker has recently been serviced at planet too.
any help would be appreciated, thanks
