regarding the WD-82742 manual try http://www.managemylife.com/mmh/lis_pdf/OWNM/1207220L.pdf

I've never had a problem in the past with lamp DLP sets being on for a long time. I don't have mine on everyday for that long, but sometimes I will have my Mitsubishi on for 10 hours up to 18 hours in one day.

I leave my set on about 6-8 hours a day nearly every day. I'm about 9 months on the original lamp so far. IMO, leaving the set on isn't bad for the lamp, but the lamp is rated in hours, so more hours in fewer days could be a reasonable expectation.

BTW, your link for the manual is the supplemental owner's manual, not the service one.

No problem. I apologize for not visiting more often lately. As for your question, yes, longer on time will result in shorter life, however being that I'm on my 2nd DLP in 10 yrs with at least 8-10 hrs/day use and I have only replaced a lamp once...I'm not worried about this one either.

The humidity is not bad, we run a dehumidifier in the summer months. I have a new bulb from Mitsu and convinced them to pay for a tech to check it out. The tech called and ahs done some research and I believe he is planning on replacing the ballast and power supply, hopefully that does the job.

Running the TV for long periods is less stressful on the bulb than cycling power multiple times a day. Most problems will occur when changing states ...off-on-off-on, etc.

Hey all, I have an issue with my 73742. Across all inputs I'm getting a flicker in brightness, where it gets brighter and goes back to normal. Seems to do it more on brighter scenes but is very random. Could do it a few times to as much as dozens of times a day. My warranty is up in November and I have called Mitsubishi and they have someone coming tomorrow 11/9. When the tech called and asked me about the issue, he seems to think it's the color wheel and has ordered one. But I'm thinking it's more of a lamp or iris thing. Anyone familiar with such an issue, any feedback would be appreciated!!

Do these sets even have an Iris? I thought they didn't?

The tech suggested it may be the iris, I don't know. He just called me after watching a video I sent him and he thinks it's the lamp and told me to call Mitsubishi to have them send me a new one under warranty replacement. He said Mitsubishi doesn't allow them to do it when it's under warranty. Am going to call them now and swap it out myself, will report back.

This is odd, my 82642 just started doing the same thing today. The picture started flickering. I have not seen this occur before today.

I guess I'll need to contact Mitsubishi and see if they will send a replacement lamp. If it is the lamp I would certainly like to get it replaced before the issue gets much worse. Right now it's only flickering occasionally.

Well I guess I should wait. Let us know if your lamp replacement fixes the issue.

That is very odd, for some reason I feel like I should apologize. My lamp will be here tomorrow, I'll let you know how it turns out. Here's to hoping that this is the fix!!

Thanks. I guess I'll need to contact Mitsubishi to see if I can get sent a replacement lamp.

I've owned two other lamp based DLP sets since 2005 and have never replaced a lamp. I still have the original lamp in my 2007 Toshiba DLP set. (Of course now I probably jinxed it,) So it's kind of surprising for me to have lamp issues with a set that is less than a year old. At least replacing the lamp is an easy fix.

Try putting your lamp on Bright mode. The 640/740/840 series had some weird flickering on Standard sometimes but when you'd turn it on Bright the flickering would stop.

How much does a new lamp cost? I was just on the phone with their warranty department and they are supposed to set up a service visit. I really don't want anyone messing around with the set if the lamp is the only problem.

I believe it's $99 directly from Mits but with all the extra charges (s&h, tax) it ends up being $121.xx. At least that's what it is for my 73736.

My WD-73C12 television is just past it's warranty period (figures) and had a failure last night. The self-diagnostic error code was "61"...meaning "LAMP-EN Detection" and the most likely cause is "Check Color Wheel / Check J6 & J7 circuitry /
Engine Failure".

I unplugged the TV for about a minute and the picture returned, but the video quality isn't as it was. The colors are off when I first start it, but they improve after a few minutes. The picture looks washed-out though, almost like I'm watching it thru a haze.

Any thoughts or recommendations??

After thinking about what the TV is doing and what I can address without buying parts, I visited the service manual and decided to try adjusting the Index Delay. The picture is much better now! I'm not sure why the index had changed on its own though....color wheel slippage maybe??

I bought a 73642 from Aarons two months ago to replace my 7yo Samsung 61". I had read through the forum before deciding on the Mits. I'm glad I went with DLP again ,my 3rd DLP set, as I really enjoyed the Samsung but the DMD chip failed two months after I had replaced the color wheel. The expense of repair plus the Samsung's age really made the decision. I hadn't planned on upgrading the TV to a 3D model but now I have everything since my Onkyo 809 and PS3 are already 3D. I wish Aaron's had a "742" so the 3D emitter was built in. The emitter and glasses will come later after I decide which though really leaning toward the PS3 glasses. Does anyone have experience how well they fit over regular glasses please? One other question I'm a bit confused as to what models used the CC or matte finish screen. Mine has the CC screen.

And I had debated on running the lamp on power saver or higher output and went with the higher setting. The lamp flicker on power saver may occur because the ballast is cutting voltage to the lamp. I wonder if it's a set cut or if it's variable depending on input. If you are having issues with lamp failure it could be a loose connection or the ballast. My TV had not been rented but was a floor display and has just over 1400 hours according to the service menu. It has a manufacture date of November 2012 so would that make it one of the last off the line. I plan on asking the store manager if they would order a replacement lamp or would I be better off calling Mitsubishi.

My televisions did it again last night. First sound went out, then the picture began freezing, then it went dark with the same error code "61". Being late, I decided to unplug the TV and let it reset itself while I went to bed. The next morning I plugged the TV back in and the light began flashing green immediately. After a while it stopped flashing and allowed me to turn it on. I may still call tech support, but I'm not hopeful since the TV is out of warranty.

I suppose this 14-month-old TV is almost dead now. mad.gif

Bought my tv last January, and the last couple of days, I've started to notice a flicker. Not all the time, but enough that I'm worried something is going out on the set. Any ideas, bulb, ballast or something else? What's the warranty on these sets as well?

How many hours on the lamp? You should have a spare lamp always on hand. The warranty is 1 year.

Not sure on the hours, but the tv is probably on 5 hours a day, so probably somewhere between 1500 and 2000. I thought the warranty was a year, so I guess I'll be making a phone call. Thanks for the help.

I'm thinking with my Mitsubishi I do. My 2005 Samsung DLP set that I used for three years never needed a replacement lamp( I also got an extended warranty that covered a replacement lamp but never needed it). And my 2007 Toshiba DLP is still on the original lamp after 6+ years(I also got a lamp replacement warranty and never needed it). Yet I'm unsure if my Mitsubishi lamp will make it to one year.

Of course with my Mitsubishi the 5 year extended warranty doesn't cover the lamp, and this seems like it will be my first DLP set that will need a replacement lamp at some point early in it's life.

Press "menu" on the remote then "2470" this will bring up the set hours not the lamp hours. In your case it will be both since the lamp has never been replaced.

DLP lamps dim over time I replace mine at approximately 6000 hours but I've never had an issue with a lamp.

The blinking green light after you've had the power pulled for awhile is a normal function as it 'boots' to some stage. I had that same thing when the main board on my 73742 was replaced. The tech said it is normal.

If the set is now running fine, I wouldn't worry about it unless it keeps giving issues.

I have the PS3 glasses and before I had cataract surgery, wore them with glasses with no problem. They fit over them just fine.
