hey well i have a 2k4 alias, frenzy 116

i was playing tonight and i tried to go into the menu, so i would get the menu, then save would flash and take me back to the main screen, that was the first problem , at the time i was running a new energizer battery

i started to play and my gun would then turn off while shooting,
so i changed that battery and that problem ended, but still i couldnt get into the menu,
the third thing i noticed was the shot counter wouldnt work either it would go to 1 really quick then hit zero again also you cant shoot ropes either you can hit about 11 to 12 then it stops for half a second then u can hit 11 or 12 again
any thoughts? and if i take it to MR can i get it fixed if it is fixable or will i have to buy a new board?
thanks
