A few users in an Italian forum have been reporting the same issue with their brand new 8605 TVs, namely the glass panel has dirt areas, halos as well as fingerprints (!!) in the internal side of the glass.
There are also reports of local service being unable to clean the internal side of the glass, making it dirtier and dirtier.
Is this a known issue? How can the internal side of the glass be so dirty...?
