Samsung Tantus Slk407w Fuzzy Image
I have a Samsung Tantus SLK407W tv that has started to get a fuzzy image. Also, there are spots in image caused by internal dirt flecks. I cleaned the lamp, glass, and lens that lamp shines into but cannot get into internals of tv to clean anything else. Anybody know the proper procedure to take this thing apart for cleaning? Is there any other reason the image will be getting fuzzy? Thank you.

Hi:
I had same problem, here's what i did. Open your unit(remove about 20 screw from the back all around. remove 2nd fan located right hand side (two screws only), and with a little help from other person open front cover slowly and you will see that there is another lens (fish eye type) along with a mirror facing down on 45 degree angle. Clean lens only carefully with a lens cleaning solution used for reading glasses for example. put fan back and cover again. If still see spots or fussy image then open again your unit and clean VERY carefully the mirror do not separate the front cover from the back as it migth lose viewing angle.
Hope it helps
Good luck!
