2010 Mitsubishi 3D DLP Owners Thread (738/838 series) - Page 284

That's good.

Thanks for the info. Is there a time frame in terms of hours, I should consider replacing the bulb ?

Its' never too early to order one to have a spare around. Otherwise, just replace it when the picture gets noticeably dim or the bulb blows, but I wouldn't expect to need to replace it until at least ~1500 hours or so of use.

My 65C9 had over 5500 hours on it and still looked good to me.

Lets think about this more.

1. 3 hours a day, 365 days a year is 1095 hours of use in one year and that is most likely a little low for the average. Ray's TV is showing well under a year's use.

2. While the bell curve for lamp life is very broad which means average is not that helpful, the average life of a lamp (THEY ARE LAMPS, NOT BLUBS) is well over 1500 hours and 5000 is not unusal. I have heard of a lot of lamps that last over 10,000 hours.

3. Replacement lamps may or may not have a warranty but if they do, it is based on time from the date of purchase NOT INSTALLATION. Often warranties for replacement lamps are 90 days to one year. So if you purchase a lamp now and your original lamp lasts 5000 hours you will have the replacement lamp on the shelf for several years. After that 5000 point you install that replacement lamp and it last only 3 months (it can happen, anything can fail). Now you have no warranty for that replacement lamp.

4. If you are only at 664 hours, you have a better than even chance it will last much longer. Since most lamps are delievered in less than a week, I personally would wait longer before getting a new lamp.

When I ordered one straight from Mitsubishi they sent it via 2 day shipping.

Good post to make me think about "not" spending a 100.00 for the new lamp right now. This TV is located in a dedicated HT room where is gets played on the weekends and that 's why the hours show what they show.
Thanks for the info as well as to others who posted their thoughts . BTW do you know if I can get a service manual to show me how to get the codes on the remote to show the hours etc ?

Would this work with the 738?

I bought this in addition to the ps3 3d glasses. looking to run 3d through the ps3

u have to have a blue ray 3 d player also

That emitter should work. I just bought that along with 2 pair of universal glasses.

Got everything yesterday I'm still tinkering with it but I was able to see 3d off the sony/imax streaming site using my sony s570.

Pirates of the Caribbean that i rented has not worked as well though, still tinkering

Experienced some random brightness level increases and decreases while watching a BD recently (The Thin Red Line, yet another strong Criterion encode, so I knew it was not the disc). And am now experiencing a consistently darker picture. 4,358 hours on this lamp. Ordered a new one and am hoping that replacing the lamp solves the problem (and that it is not a light engine issue) as Mitsu's recent announcement of immediate cessation of making DLP RPTVs has me wanting to sell the 73-incher and step up the the 82 before the end of the month.

That's what I did even though I didn't need another TV. I already have a 65738 and an 82740 but went and bought the 92742 (was waiting for prices to go down) because I knew that we wouldn't be able to ever get any DLPs 'cause no one is going to make them. They are the best screen size for the money and who knows when the LCDs, Plasmas, etc. will go down so much to be affordable in this size screen?

Guys how do I factory reset?

I am tired of searching.

I had this all bookmarked but lost everything

Thanks

System Reset is not the same a Factroy Reset. Factory Reset wipes out all of the consumer adjsutements, setting and memories.

System Reset is basically the same as unplugging the TV and plugging it back in again. It is for situations where the TV seems to hang-up. It is like rebooting a comptuer. It does not wipe out memories (except for time).

A factory reset wipes out memories, however there may be a few that are not wiped out such as parental lock codes and Adv Picture mode settings. MENU>1>2>3 is how to do a factory reset.

Look in your Owner's Guide Trobleshooting section there are two entire pages on the different resets and what they do.

My understanding is that the lamp warranty clock starts ticking from the date of purchase not from the date of installation. Just something to keep in mind when ordering spares far in advance of expected time of need. This is of course even more of an issue now as many of us are likely concerned about legit/non-gray market lamp availability in the future.

Speaking of, I'm disappointed to note that the lamp I ordered Saturday with 2-day shipping did not/has not shipped today as expected. Shipment is "pending." Is this unusual? I'm wondering if MitsuParts is seeing a big uptick in lamp orders right now.

Hey all - had my 65738 now for about 18 months, still looks good. Hours are up to 5500 so I ordered a replacement lamp to have handy. I have noticed that the fan is louder than it used to be. Is there any maintenance I should do when I change the lamp for the fan? It seem way too loud. Has anyone replaced the fan?

Doing a quick search for wd65738 fan, I got this hit, http://www.hotpriceparts.com/servlet/the-14504/MITSUBISHI-WD-dsh-65738-FAN-GM1206PHV2-dsh-A/Detail

A fan for $26. I Then found a different post on eBay, and the fan looks completely different, http://www.ebay.com/itm/MITSUBISHI-WD-65738-FAN-BG0703-B042-00L-/330804364177

Can anyone confirm which is the correct fan?

Anyone had any issues with the fan?

Thanks!

Please help, I am getting mixed messages on what I need to get into the 3D game. The owners manual suggests that equipped with the latest firmware, no 3D emitter is required, however several vendors tell me I need to purchase an emitter. Do I need an emitter & glasses or just glasses to watch 3D DirecTV programming on my Mits 65738 that is running firmware 12.08?

Thanks

I just got my 3D glasses this week and am also still learning. My understanding is there are two options: the IR emitter route or the DLP Link route, if you look in the settings on the menu you will see you can select one or the other depending on your glasses. I'm only using Blue Ray 3D, not DirecTV so I'm not sure if there is a difference in the applications. But, basically if you purchase IR emiter glasses, then yes, you need an emitter that will need to plug into the back of the TV. The other option, which I chose, was to purchase DLP Link glasses which do not require an emitter. So far everything seems to be working ok. Page 33 of the latest manual posted on Mits's web site shows all this but, since you have the latest software you can set the Source Format setting in the menu to Automatic and the TV should detect any of the formats listed there on its own: side by side, top/bottom, checkerboard or frame packing. Just make sure your HDMI cables are 1.4 compliant. Try to find out what format DirecTV broadcasts in. Picking out which glasses you want is a whole chore in itself. But there are some informative threads in the 3D section of this web site.

Really - nobody has had any fan issues or loud noise and replaced their fan?? Very hard to believe.

I have had my 73838 since August of 2010. I can honestly say that I have never even heard the fan on my set. I am on my second lamp, the first having lasted over 5000 hours. I am not aware of any hearing problems , but I never even know when the fan comes on or goes off. There must b a wide range of behavior for that component.

Thanks marcusj50.

Just to share some information I found. There are 3 fans in the WD65738. They are,

Fan Dmd 299p359010 $52.8
Exhaust fan 299p357010 $15.5
Scirocco lamp fan 299p321020 $17.9

The fan that I think is loud is the lamp fan, so I'm going to order one of those and replace it when I replace the lamp.

I tried calling Mitts suppport and they refused to send me the fan or help at all. They said my unit was out of warranty by 4 months, meaning that this fan lasted 16 months! What a shame that they sell me a tv for $900. and the fan only lasted 16 months, and the refused to help in any way. I think this will be my last Mitts tv ever!

Either way, that's a pretty safe assumption since they've dropped out of the RPTV business .

In case anyone else cared/was curious, the lamp did indeed ship on the Monday after Saturday order. The tracking was just very late in updating. Arrived overnight so FWIW for anyone else in Southern California, it's not really worth it to pay for overnight or 2 Day service unless you absolutely want guaranteed date delivery since the lamp will likely arrive from Irvine in one or two days.


Check the 2011 and 2012 owners' threads. I recall an extended fan discussion somewhere regarding a guy who mounted an additional fan on the outside of the display's ventilation grills using the USB jack for power, purportedly for additional heat exhaust. He took temperature readings and everything, insisting it was providing additional chill over the objections of those who argued that obstructing the grills in any way was exacerbating the very issue he was seeking to mitigate.

Anywho, unless your fan is squealing (in which case I'd recommend a little WD-40) the increased noise is likely due to it being caked with a light or maybe even heavy amount of dust/dirt. It depends on how dusty of an environment you have the display in. Do you have good clearance behind the display? Have you been checking the grills to see if they need to be dusted/vaccumed? You may have some luck using an appropriate brush attachment to clean the fan when it is perhaps exposed when changing the lamp.

mits makes alot of cash of of lamp sales, so I doubt lamp availability will dip at all over the next 5-7 years.

Just because they make some money on lamp sales doesn't mean they can't make more money elsewhere and cease the lamp sales. And it's not my understanding that Mitsu actually makes the lamps? Aren't they manufactured by someone else and simply sold via Mitsu?

One can still order lamps from Samsung, and they've been out of the DLP business for years. I am not concerned about future lamp availability issues with Mitsubishi.

well given the fact that the fan is having issues and less than 2 yrs old and they won't support it, I wouldn't by any type of tv from them again.

Yours is a warranty issue, and your warranty is clearly expired. Lamp replacement is part of regular maintenance.
