It's really not hard at all. Now that I know how it comes apart, I'd say the whole process would take about 15 mins.

Here's a pic I just posted in another thread to show where the screws are (on my WD73740) if your curious.



Red screws are in the back, green covered in the front.

It made a huge difference on my TV, but my mirror was exceptionally dirty. biggrin.gif

BTW, to see just how dirty your mirror is - open up one of the side "portholes" and wipe off a section of the mirror.

WARNING: if you do this, you're gonna end up cleaning the whole mirror. wink.gif

Oh yeah, and don't try to clean the whole mirror from the porthole - ask me how I know! tongue.gif

It is a bit bigger job with the 92840. I won't even attempt without a couple of people here who are willing to hang in and around for a few hours.

Does the screen attach a lot differently on the 93" vs. the 73"?

For me, it would only take about 15-20 minutes now that I know what I'm doing.

See this thread, but I didn't really describe the cleaning method - I just used glass cleaner and paper towels.

New Thought: What will be the replacement for our dead Mits'?????????

My 82740 Mits is about 3.5 years old now and 6000 hours on the lamp. What will be the replacement for the cost effective DLP units (paid $1700 new) in the 80+ inch range?????

DLP are no longer being produced, but for other options, see this thread.

Is there a way to disable the power saving mode described below?

I have tried pressing sleep timer to turn off and looking in the menu for any power saving controls or whatever. I have everything working now, but in XBMC regular when watching a 3D movie in Total Media Theatre 3 I have to continuously press a button on the remote because that message keeps popping up and it is infuriating. Is there no way to disconnect the power saving settings part if it cant see the media which is clearly working fine?

I have a WD 82840 that I purchased in Dec 2011 and two days ago it started the constant green blinking light. From reading other posts, I see that other models have had bad caps on the DM power board and replacing those caps has corrected the issue. I believe my set does not have that same board in it. If any one can help please post.

Slow or fast blinking? Check your manual. If you have a timer set the green light will blink. I believe it also blinks until the lamp cools down. All are normal functions.

My bad, I have misled you. The set does not turn on and it is a fast blinking green status light. And by timer do you mean the sleep function? Have never used the sleep function on the set or any other timer feature. I have tried holding the power button on the set in for 10 seconds or so, and hear a click sound like it is trying to reset but then it goes back to just blinking the green status light.

Yes, left it unplugged over night, plugged it in next morning and same issue. I think it may be the main board. Still doing research.
