How to remove display window to clean dust? I cannot see my display.

Sounds like you may have a dust/dirt issue inside the machine. Open the case, and clean around the CPU fan (it's the fan that sticks up from the board, with a large fin type thing under it). I use a paperclip (carefully!) to remove the dust from inside the fins.

Also, it's worth checking the graphics card (if it has one) as they can also get dirty, and cause problems starting up and displaying. Check for dirt, and also check to see if the cables are connected correctly.

There are other reasons this could be happening, but try these two first.

Power down and disconnect AC power from your PC. Remove the AGP card and DIMM again and use some "canned air" or dusting spray to get any dust off the contacts on your motherboard and your memory and AGP card. Wiping the AGP card contacts with some isopropyl alcohol (also known as IPA or "rubbing alcohol") and a clean, lint-free cloth can also help. When everything is dry, put your card and memory back in and try powering up again.

Hi there you are right in your place. Its a dust. but you need to clean in different way. because the dust stick in side the lens and its not easily clean by that dust clean option. Some how your camera get moisture and dust stick on it. After drying the moisture that dust permanently stick there. So i suggest you visit a service center and submit your camera for manual cleaning. They use alcohol and cotton so the dust easily clean by them. Thanks.

There are two main causes for this dimming:

1. Dust & other particle buildup on the front of the display glass and the rear of the display window. This can be cleaned.

Cleaning the display is easy, but you need to be careful so you don't break the glass.

First you would unplug the microwave or turn off its breaker.

Then see the video here that shows you how to remove your control panel assembly in less than 5 minutes.

Next, disconnect the keypad strip as shown in the photo below, then remove the screws that hold your circuit board in the plastic frame.


Then carefully (since the display is made of glass) remove your circuit board.

Using a soft cloth (since paper towels can scratch) lightly dampened with non-ammonia cleaner (since ammonia can damage some polycarbonate plastics), gently wipe off the front of the glass.

Then gently wipe off the back side of the plastic display window in the plastic control panel frame.

Reassemble, reinstall, and power it up, and it should be brighter, sometimes a whole lot brighter!

If that does not brighten it up enough, then...

2. Your vacuum display tube is wearing out and either the VFD display tube or the whole control circuit board must be replaced, depending on your model number, which you didn't mention.

If you'll contact me with your model number, I can give you an estimate and free do it yourself info.

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.

Unfortunately, no. Unless you're willing to risk breaking the display lense on the Omni terminals you can try and pry-off the display lense very carefully starting at the leftside edge of the display lense and slowly lift off the lense. By doing this, you'll need to let the double-sided sticky tape used to apply the lense lift off the case/housing. In most cases it would be wise to send in the terminals for general cleaning/maintenance. I can do these for you cheaply.

Hello timbick45,

You want to remove the top rear panel. Remove the screws and the top, along the sides, and along the middle of your TV (from the rear). Onec that is done be very careful because the mirroe is attached to the rear panel of the TV. set the back down and with a clean cloth and a can of air remove the dust off of the mirror, use a light window cleaner, after removing the dust. To clean the bulbs just use air to blow the dust off (not not attempt to clean the bulbs with any solvent.

I hope this helps

Thank you,

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.

the light engine is that part that displays the picture on the screen. its like a filmprojector. if you need the complete LE, you run in about 1200-1600 dollars.Mitsubishi DLP's are known for collecting great amounts of dust, so try to clean the filters first and remove all the dust you can find.be careful,do not use a vaccuum as they can damage the electronics and the fans.....
