I have a mitsubishi 63 inch 1080pi and and at the bottom of the screen it has a black spot about 1 inch on it...what is the cause of it and what need to be did to fix it?

it might be a dead bug or something inside the projection area behinb the screen. If you gently shake theTV (with it off) does the spot then move when you turn it back on? If so, you can get inside the projection area and vacuum it out.

Round black spot in middle of the picture/screen

Hi :-)

The round blotch your seeing on the screen is the melting of an acrylic lens inside the light engine. Its a design flaw which unfortunately Infocus will not stand behind. To fix this problem requires opening the light engine and putting an equivalent lens in place. This task is very involved, but this problem is repairable and you need a glass smith to cut the right size lens from the original.

Black spot in bottom of tv

I just had my caps replaced and after the tech put it back together there was a spot. He tok the screen off and cleaned the mirrors around the bulb and the large mirrors(they were reaaaalllllly dirty. It did brighten up the picture and it looks crisper, oh and the spot was gone.
P.S.. Like nettiser stated. If it's unde warrenty have them do it. If you drop something "you will be pissed" if you don't !

Hazy yellow spot in the left lower corner of the screen

It could be a cob web inside the tv or something laying on one of the guns, like a dead bug. If it's a cob web, you should be able to move the tv a little side to side and see it change from the moving air current. I would remove the back and vacuum off the lenses of the guns and look for cob webs. It's safe to touch and clean the lenses, just don't touch any electronics.If this doesn't fix it, it's probably fluid starting to cloud up in the guns or IC chip problems.

Water stain on the front of our Akai PT5499 Projection TV

Hmm... should evaporate on its own. The only way to access behind the screen is to take the whole back off the TV, and then inside theres another panel that covers the main reflector and screen. I wouldnt recommend doing that just for water tho.

Dark spots on tv

I have the same TV, and I was getting the black spots on my screen as well. It is dust settling on the bottom mirror. Yoiu can call Mitsubishi and spend 150-200 on getting it cleaned, or you can do like I did and take the front panel off and the 10 screws around the edge on the back of the black plastic border around the screen. Then lift up gently and have someone hold the screen for you and gently dust the bottom mirror. I did this by myself, but it would be wise to have 2 people do it.

Screen spot

Since you have a black spot,you need to look at the mirror or inside screen. If it were a certain color, like purple or yellow, for instance, I would suggest a lens or picture tube, but, since it is black in one spot, I would suspect debris in those areas.
