With all the TV troubles and blown ballasts people are having with aftermarket and wrongly spec'd lamps, I wouldn't risk it. Stick with the correct lamp supplied by the manufacturer.

There is no orange LED. If it's flashing yellow, check that your lamp door is completely closed.

If there is no orange then it must be red but it looks orange to me and my wife. I have never replaced the lamp (bought it in Dec 2011) so maybe it just needs a new lamp?

Nothing really important to say. I am close to 9000 hours on my 92840. The extended warranty is good till around Christmas this year (2015). I hope the set hangs in there another 12 months or so. No maintenance other than lamps so far.


No affordable jumbo displays out there yet. The 2015 Vizio M 80 inch is $4K but that is not big enough and all the ULTA HD stuff spec wise is still in flux. Hoping the old monster keep going long enough till there is a viable replacement on the market. I will be calling Mits for yet another lamp before the NFL Regular Season starts again. Good luck to all of us with the 2011 sets.

I want to bring this up as mine (WD92840) just now wouldn't power on for the first time. I've owned it since 12/2012. I read that I should use Mitsubishi lamps which i'm fine with. I'll probably order 2 of them to have a spare. (or not)

With the lamp out is there any cleaning to do for the dust? I'm assuming no compressed air so nothing gets on the mirrors but wanted to see what is recommended since i'm changing the lamp now.

I should note that I'm assuming it's a lamp since its a solid red light but wanted to check (Lamp wont start). I don't know the total hours since it won't come on but once it's replaced i'll post how much i got out of it.

EDIT: do the lamps include the housing form Mitsubishi?

Why? The warranty on the second lamp will expire, and you would just waste the money. You should get 3000-6000 good hours from a lamp, and it normally dims a lot before failing (as you'll no doubt understand when you fire up the new one).

Good point. What is the warranty on the bulb? 1 year? Mine didn't dim that I know of.. Just didn't start up the next night. I had them second day air it so i can get it a little sooner and make it before the holiday. How long will Mits keep these bulbs around?

I've got a big shop vac with a hose of course. You just stick that down where the was and suck the dust? Or a different location? Any other maintenance?

They all dim, it's just so slow that it's hard to notice without a meter to measure it until it's really dim. I only get about a year out of my lamps until they dim below 30ft-L.

Warranty is 90 days. Vacuum the vents.

Lamp is in and works great. I'll check # of hours tomorrow. Is that power on but holding a remote button? Is there a way to check when it's already on?

Not much to see but comparison. New one on right

Hey gang...

Just dropped in to check on everyone's experience... Mine is still going strong, with only one new lamp, thankfully. I'm really going to miss this set when it's gone *, like GTGray... I worry about how I'll replace this beauty. Nothing currently is of interest to me.

Hoping it lasts a few more years, that's for sure!

BTW... Alan P-- did you ever find the problem to your strobing picture? I know the assumption is the ballast... but I'm curious if you've replaced it again. I've always had a bit of this issue on my set, kinda comes and goes (mostly goes, for long chunks of time, then I'll notice it one night... then it will be gone again).

* Ever since we got Mits to fix the damn red/white issue.

RE: Strobing.

Yeah, mine kinda comes and goes too....the last time it got really bad, I just kept on with the same lamp/ballast and it eventually stopped the strobing (I think I've been replacing lamps prematurely because of this...as soon as I saw the strobing I would put in a new lamp, have gone though 3 or 4 lamps in as many years). Now, like you say, it kind of comes and goes but never stays.

i have a brand new lamp I ordered about 6 months ago but have yet to install it. I'm waiting until the strobing is much more prevalent now.


I'm with you...there's nothing out there right now (for the price) that can compete with these giant DLP sets. Fingers crossed mine lasts until there is.

Where are you located? The higher you list it, the longer you'll sit on it. Buyers almost never appreciate the value in these sets, so sellers are at a disadvantage. I'd say $600-$900 if you need to move it, higher if you can afford to wait a few months for the right buyer.

Anyone know the response time for game lag etc... For the 840? I'm just curious, comparing to some current sets I'm lookin at and I've loved my 82840, and game lag doesn't seem to be an issue at all if ever, but I'm perhaps moving to another type of set and curious how comparing response times might be

Lag is not a problem with Mitsubishi DLPs. I remember reading that the early Samsung DLPs had a problem with lag, however.

That's what I mean mainly, are these 840 mits models lag free? I mean I've gamed a ton on mine, and I've thought it was lag free but it could simply be a super low refresh rate.

In any case, I guess my question is bumping to an led set will introduce me more to lag correct?

I'm lookin at the Samsung ju7100 75 model and I'm just hoping that gaming on it would be similar to my 82 840

Stink bugs!!!!

Inside of my 92840.

Literally flying around and doing some unmentionables on the screen?

Any suggestions on how to get these suckers out before they have babies?

Also, how did they get in there? I would think that a filter must be missing that needs to be fixed.

Thanks.
