there may be dust behind the screen & also on the reflecting glass. u will see that upper back portion cover is removable. remove it & see that glass there is glass on inner side of cover. clean it, also clean the screen. u will see there are 3 picture tubes faces on bottom side, clean all of them.

if it does not work then u can increase brightness of tv by increasing "screen" control of tv which is on the lower back portion of tv. this can be done by any tv repair expert only.

try blowing out all of the dust from your keyboard using a fine air blower from an air compressor making VERY sure there is no MOISTURE in the lines.

You will need to remove the back cover. Here you will dust the lens with a pressure can of air only. Then you proceed to clean the lens with an eye glass damp cloth Get these from an eye doc). As for the mirror, you must use real caution. This mirror is made of a stretched plastic. The best way to clean this is to use a new feather duster. Do not even think of using anything wet to clean this mirror. It is very fragile. Let me add, that you want to do this from the rear also. Next, I would not recommend you try to pull the front cover (screen) off. It would be next to impossible to put the screen back on the TV. You will also feather dust the inside of the screen from the rear. No wetting solution here. Be sure your TV is not plugged in. Thanks for asking and show all hands of support!

Read Each Step Completely - Make Sure 3 Color Guns Are Off And Cool -
----------------------------------------------
1. Remove Rear Dust Cover 2. Remove the Front Speaker Cover May be Held In By Plastic Pins and or Anchors on the Bottom Note" - Remove The Plastic Cover Just Above Speaker Cover Maybe 2 Piece. Remove The Screws Holding Top Of Speaker Cover. Then Pull Toward You the Bottom Maybe Anchored So Lift Up. 4.Once Speaker Cover Removed, May Have Screws Just Below Center Plastic Cover Remove Them, Now Remove Center Cover Between Speakers -NOTE" Do Not Touch, Move Any Color Convergence KNOBS" - Lift Front Screen UP - Towards Roof - It Has 3 Flex Grab Anchors On Top And 2 Pins One On Each Side Of TV Frame. - NOTE" Lay Screen On Floor It Is Plexi Glass So It Will Brake If Bent Or Drop Hammer On. NOTE"- May Have To Remove plastic Cover Frame positioned Around Front Screen And Then Remove Screws. 5. I Use Windex Glass Cleaner And Either Cotton Balls Or White Tube Sock On Color Gun Lens Covers And Clean Mirror Like The One In Bath Room. 6. Take White Sheet Or Bead Spread And Anchor On top Of TV With Weights, Stretch Around Each Side Of TV Use Chairs To Anchor On Each Side Of TV. Place Dust Cover Or Heavy Card Board Where Plexi Glass Was Positioned. 7. Turn On TV - go To Rear and Now You Can Adjust Colors Brightness And Low Light - High Light - Horizontal - Ect....While Looking at Picture. 8. Install In REVERSE - Order Just Wipe Color Guns Lens Last. Note" - If you have Wet/Dry Vac or Fan Or Blow Dryer Take A 2 - to - 3 Inch Paint Brush And While Brushing Circuit Boards Any Dust For That Matter Blow Dust Off And Out Even Brush Speaker Cover"...ECT...Do This Before Any Cleaning 9. Just A Thought If You Ever Want to Change Color Gun Cooling Oil - Wrap All Circuit Boards With plastic Bags And then I use Bath Towol And Paper Towols To Catch As Much Spill As I Can And Then Spray With Windex To Make Dry While Blowing Air Onto Spill - Also I have Found Clear Mineral Oil Like Johnson Baby Oil To Work As Well If Not Better Then Glycol Oil. I Get For $2.50 For 20 Oz Bottle.

do not take black box apart the front screen will lift up but do this gently and if you take the frame off the screen make sure you do not allow to bend it is plexie GLASS and will BRAKE if you need to support it put a chair in front with a pillow for the screen to sit on....be slow take your time remember to blow out dust before cleaning miorror and projectors lens then blow out just before putting front screen back, then wipe the lens again last before putting dust cover back on the lower rear.

Shoels,
You could replace the screen and glass lens/cover but I having done this procedure a few times, don't think it's worth it as the Razr is a fragile phone and the case's just snap fit together.
There are cell phone repair shops (depending where you are located) that will replace both the screen and glass cover for a fee.
I personally would just look for a shady spot to view my display in daylight, as the V3 isn't worth the trouble/expense to repair (in my humble opinion of course).
Good luck

Wow, You are asking for a complete disasemmbly. If this is necessary, you have to remove any screws you can find that are connected to the front panel. Usually they are in the top of the set ( you'll find them after removing the mirror panel and mirror ). I wouldn't remove any tubes as the tube convergence would have to be all reset and that would require a cross hair generator. I do hope this has helped in some way, but all I can do is send you my best wishes as I certainaly don't suggest disassembly if there is any other way. Good luck

unless the warranty of your scanner has expired, you have to disassemble your scanner and clean the dust inside.
