A while back I thought my new TV had horrendous light bleed. However after a recent cleaning of the unit I noticed that these patches of lit moved and more showed up. Turns out it was actually streak marks on my TV from being cleaned that give a faint yellow tinge to parts of it when black screen is viewed in the dark. O matter how hard I try I can't get rid of these, I can move them about but not completely remove them. So how do you all clean your TV's and how do you get rid of any streaky marks such as this?
