I bought a used axe FX 2 mk I last week and I've been noticing the screen has been flickering once every 5-10 minutes. The screen doesn't turn off but the contents of the display would disappear, leaving just the green screen background for like a millisecond before coming back. Tone doesn't drop out (I think), so is this a normal screen refresh thing for these older displays? or is my display on its way out 
? Still have the return window for it so any quick help would be greatly appreciated! Thank you!
