hi there canderous here
sounds to me like your beam reading lens could be a bit dirty .if you ever shone your torch on to a wall then coved it with paper this beam is reduced by more then half same thing is happing with your console there are air born dust on your beam.
therefore blocking the lens from reading it i havent lost you
there are a few mesures that you can do to fix it you could try buying a lens cleaning disk i perfer wet ones they tend to clean better then dry then after running the disk wait for as long as its mentiond in the instuctions on the disk
this same problem happend to me earlier today i just did what i said above and it fixed it not even needing to reload.but anthor thing is your system near any magnetic sorces like amp or sub or anything like that those can make it go funny .
IM HERE IF YOU WANT SOMETHING DONE RIGHT
