As I was cleaning the screen I noticed 3 very small spots that at frist looked as if they dropplets from the cleaner. The largest is about 1.5mm in diameter the smallest .5 mm dia. Right side of screen from center to the upper right corner. My guess is that there is something on the mirror? Any suggestions, Thanks in advance

Re: spots on screen
If it looks fluid it's more likely something like windex or whatever you were using to clean the outer fresnal screen with got between the fresnal and lenticular screens. There are actually two screens there sandwiched together...

LCD screen is quite different with crt screen. You should be careful while do cleaning. Unplug the power supply before do cleaning.
How to clean lcd screen:
You can use isopropyl alcohol, hexane, petroleum benzine, glass cleaner with ammonia free.Apply the liquid to soft and clean cloth then wipe your screen. Repeat the steps until your lcd clean
Grease look on screen? Just use dampen cloth with water instead use above liquids as the may smear the contaminant across the screen.
Green is missing from the area where you see the pink (actually magenta) spot. This might be due to a large amount of dirt on the green lens. It may be due to damage to the face of the green picture tube. You need to remove the front screen so you can look into the lens and determine that.
Depending on the make and model of TV, the screen may be held on by snap fasteners and come loose when you pull on the plastic bezel surrounding it. Or the bezel may pull off to reveal brackets screwed into the cabinet that secure the screen. Or there may be a trim strip under the screen that pulls off to reveal screws. Remove those and the screen will swing up and off.
Once you can see the lenses, clean them with a soft rag and glass cleaner. With the set on, look down into the lens and you can see the face of the picture tube. If you see a dark spot on the face, the tube is damaged and would need to be replaced
The HD-ila sets accumulate a lot of dust in the light engine. The worst offender is the little fold mirror just under the lens. I take my set apart about every 8 months or so to clean all the dust from the light tunnel and all lenses, mirrors, diffusers etc. The picture really regains it's pop when this is done. Unless you are a skilled technician though, I would recommend against attemptimg this procedure as you need to disconnect the individual color lcds. Check with a local service center to get it properly cleaned.
The gray spots are caused by dust on your lens, very easy to clean.
Power down the TV.
If you open the right side access panel (right side as you are looking at the front of the TV) you can see it in the middle, it's not very big. Using a scratch/lint free cloth, gently wipe off the lens or use a vacuum to **** up the dust being careful not to actually touch the lens.
Replace the access panel and enjoy your spot free screen.
I fixed it!!!! If you can open one of the sides (on the JVC there is a little door with a screw), then you can clean the projector lense in the middle on the bottom. It kind of looks like a big light bulb. It seems there is just dust on the glass that is projected onto the screen. We had a big gray spot and cleaned it with a damp glass cloth and Ouila! It disappeared. I scored MAJOR brownie points with my husband for this one! He wanted to replace the TV!
why do i have blue spots on my grand wega small blue spots that flicker like stars shows up with black backgrounds it sounds like sony dont want to make good on there products by admitting they have a problem i had it cleand like they said witch cost me more money and spots are still there last time i by a sony.
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.
