How to disassemble the back cover to reach internal display panel to clean it up from a tiny dust?

Hi Alonzo,
To clean the dust inside the screen, you will have to disassemble the LCD panel. It is a very risky job and there is every chance of damaging the LCD screen unless you have a real good experience of doing it. If you are not good at doing such jobs, please let some professional do it for you.

Check for more screw(s) behind the label/sticker. Also, you may need to have a flat edge screwdriver or knife to prise open the remote.

condensation inside a watch means the watch's internal temperature and humidity reached dew point.
The watch needs to be disassembled "completely" and dried out. Get the battery OUT! Get a can of dust remover spray and get it dry. You can use some alcohol and a swab to clean it too. But careful, alcohol may act like a solvent and the parts may melt. If its been a few days, it might be too late. If you don't have the tiny tools or patience to do this yourself, try a local jeweler. They'll tell you right up front if its shot or not...

hello!
the problem is display panel connectors or panel itself(bad case). To solve it, you must disassemble the set till the point, when you will be able to see
t-con(display controller). It, usually have metal shield over it. you need to unscrew those tiny screws, may be remove sticking foil too. After you see the board itself, there are 1 or more flat ribbon cables connecting t-con board to display panel itself. Plugs have plastic locking, fragile! First, unlock the left side(opposite to your view) and pull cable out, then carefully reconnect it. If more, than one, repeat the procedure. got working? assemble everything back. Still have the problem: try to do the same with the other end of the ribbon(s). those, what connect display's boards. You may have insufficient space to reach plug's locks. Invent something to accomplish the task: use tweezers or metal picks. Try not to break anything. In most cases this problem caused by dust/dirt accumulation at those connectors. If nothing helps, I've seen the panels itself doing that. that's the end of DIY project, may be TV itself, unless you purchased extended replacement plan. cost of the panel will void any reasonable repair!
good luck,
thanks,
Alex.

Hi

Switch off your printer. disconnect the power cable or USB cable, and take him out or your room, take one blower and open the printer front cover and switch on your blower and clean the all dust and paper scrap...

The camera has to be taken apart. First - the front cover, then the back cover. You will need some compressed air.

Hello...The problem you're describing is related to the green lcd and most likely the main board(green channel). If the focusing removes the purple(you have *that* much dust in the unit?) then it *is* dust. You should be able to focus on the dust particles twice--dust on the front of the lcd and dust stuck to the back of it. I'm gonna give you the color table so you know what to look for and what you're seeing. Red LCD=cyan(baby blue) onscreen; Green LCD=violet(purple) onscreen; Blue LCD=yellow onscreen
If you have a lot of dust(and the green lcd usually is the main culprit by the design of the lcd panels around a glass "cube" internally) you might try blowing some air into the unit when it's cool. However, the unit probably needs a good cleaning--remember to clean the dust filter! To properly clean the unit, a trained tech will have to perform the job. The lcd panels are DELICATE and precisely positioned for displaying a sharp image.

No the front panel will only give you access to the CRT circuits. Remove the back panel. UNPLUG your set. You should be able to reach inside (its a stretch for sure) to clean the screen, clean the tubes and if you reach up behind you can actually clean the mirror. This will greatly improve your picture. Do not use windex just a damp soft cloth then dry with a soft cloth. The mirror cleaning is most important to get a nice bright picture. Over the years the mirror tends to get dull. Hope this helps.

Well, I pretty much knew that the display would have to be disassembled to clean the dust out. I should have been more specific by asking if the display "could" be taken apart to clean it out, especially since the dust is in between the image and light source layers.

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
