Same here-1 lamp, no maintenance.

Mine is also about 4 1/2 years but I use it in the bedroom so I don't think the hours on it are a lot. I did clean the mirrors on my old 62525 and it did make a big difference on the picture. I had step by step instructions to do it at the time. I haven't seen mirror cleaning instructions on the newer models so don't know how to do it on them? What are the hours on yours that you think you need to clean it?

I have a WD 65-738 model and recently moved from AZ to GA. I've had the tv for about 4 years. When the movers dropped it off and I set it up, the bulb blew, it was about that time anyways. Well, after ordering and installing the new bulb, every time I turn it on, it starts normal and after about 30 secs it starts to flicker and cuts off to the solid red light like many of you have stated here. I ended up replacing the ballast and the same problem continues to happen. When I check the error codes though, all I'm getting is error 34, lamp cartridge failure. I can hear it "flickering" when the screen flickers (if that makes sense), anyone have any ideas what my next step should be? Thanks in advance...

Did you get a new genuine Mitsubishi lamp cartridge or a 3rd party one? If not genuine, that could be the culprit.

I used the original housing. I just switched the bulb.

With a genuine or aftermarket bulb... The same thing applies - if you're not using original Mitsubishi parts, that could very well be the problem as lots of people have run into issues using aftermarket bulbs and/or housings.

If you didn't get the lamp from Mitsu, that's your culprit. Common thing w/ 3rd party lamps.

I have never changed bulb in my 82838, and I figured it's probably time to do it soon, thinking that it may be around 6,000 hours. Tonight checked my 82838 lamp timer: 11,681 hours!!! What!??? How long do these bulbs last


Definitely high time to order a spare bulb methinks

You should notice a significant difference once you get and install the new lamp !!!
If I were you I would order it straight Mits and not from some 3rd party vendor.
Post up once you get the new lamp !!

If you have it on the lower brightness lamp setting, they'll last much longer than usual. My original lamp was on the lower setting, and it had 9,000 when I replaced it(too dim).

I was I the same boat as you. I was definitely surprised to see 10,000 hrs on mine.

I was amazed to see the difference when I put the new bulb in. My eyes were getting used to the dim bulb. Believe me, it will be like getting a brand new tv.

Sorry, I've been busy so hadn't had time to look. My TV says that I almost made it to the 7000 hour mark. Not too bad I must say for a bulb. It has been running in ECO mode the majority of its life so that probably helped. So I think I should buy a bulb that way I'll have a spare in case something happens to the new one. Now I remember that the bulbs for this TV used to be going for $99 but after reading the past couple of pages it seems that is no longer the case. So where is the best place to get a bulb or is it still direct from Mitsubishi?

I would not trust getting it anywhere else after reading a lot of different ads. Some talk about original Philips bulb, other talk about original Osram bulb. Looks like everybody is lying, and I sure don't know who to trust!

My take is that the only way to be sure is to order it from mitsuparts.com.
$118.90 for bulb, $10.00 for shipping, $5.00 for handling plus sales tax for a total price of $142.92 to NC...
