2009 Mitsubishi Owners Thread (C9/737/837) - Page 355

I just want to say a big thanks to the members of the AVS forum. Did my first lamp replacement today and it was a piece of cake. I was worried it was something else, but researching here and reading about the Lamp light going to solid red I ordered a Mitsubishi replacement bulb. Received it in about 5 days. Had my 11 year old son help me turn the tv around and after unscrewing 3 screws, pulling out the housing, replacing with new housing, and screwing back in the 3 screws I'm happy to say I'm up and running again.

This is coming from a guy who has literally no mechanical skills what so ever. So thanks for all the help guys!!! I love my 65737

My 73837 says 11160 hours but it still looks really good. Not sure if a little dim in the daylight.
When do you all recommend a new bulb?

You are on the outside of a very long lamp life. You do not need to replace the lamp until it stops completely or gets too dim, however since you are on the end of very long lamp life, you may want to purchase a new lamp now so you have one when needed.

11,160 is a lot of hours even for about 3 - 4 years. You got your money's worth on that lamp.

I have 6825 on mine and I thought that was a lot.

Thanks for the reply. I did not even think about it until reading this thread recently. What is the thinking on the amazon priced generic bulbs vs. the 40 dollar higher manufacturer one?

Buy one directly from Mits, you will definitely notice how your old bulb has dimmed after you replace it.

I bought a bulb from amazon and its working great. Super bright after changing bulb.

I may be mistaken but I believe that mits is uses phillips bulbs. be sure not to handle the bulb directly. the oils from your skin will cause a hot spot that can destroy the longevity of the bulb.

Anyone else ever have an issue with the time and date being wrong when turned on? This has been going on for a week. I've had this set for nearly 2 years and this is the first time I've seen this. I know my time zone/daylight savings settings are right. I've even tried the hard reset to no avail. Any ideas on how to fix this? Should I go to the service menu and Initialize the set?

Mitsubishi does NOT use Phillips lamps, they use OSRAM. If you using another brand and it fails and damages your TV, Mitsubishi most likely will not help you. Use a lamp from Mitsubsihi and have a problem, they are known to help you.

You can buy origial equipment Mits factory lamps from Amazon. The price is the same or was when I bought my last and since I had Amazon Prime it was overnighted for the $3.99 upgrade fee.

If your TV is one of the models for this thread, I do not know and cannot think why you TV changes the date/time. The TV might wipeout date/time in a power failure (I am not sure). According to the owner's guide on Mitsubishi's web site, it does not have automatic clock set.

However if this is a model that is older and has automatic time set feature, often channels have incorrect information, especially cable channels, that reset the time. Also analog recordings from channels with automatic time set channels may also record that signal and when you playback the recording at a later time, it may reset a TV clock to the time recorded. Usually if you set the clock on manual, it will ignore the automatic time set feature. I had this problem on an older TV and it took almost two years to figure it out.

Hey all
I have a wd65c9 and was wondering if anyone has a good video calibration settings? I use it mainly for blu rays and 3D blu rays. Any help is appreciated

It depends, I have recently calibrated my wd-65837with an spectroradiometer using the Advanced calibration controls but that's with about 600 hours on the lamp. if your lamp isn't at a similar point in its life the settings will not be accurate. they probably wouldn't be accurate anyway but you can see if you like them as our sets are close enough ,parts wise.

I used a PS3 as the pattern source with AVS709 patterns.
if you have a XBOX 360 it may require a few bumps up in the brightness control to compensate for its non linear hardware gamma crushing blacks in some games. salt and pepper to taste where required.

keep in mind my set has a auto iris that could throw things off for similar sets without an iris. I calibrated with APL patterns to compensate for the iris.

good luck.

Hey Cid
Thanks alot for the response ill give those settings a try this weekend sometime when i find time. Thanks Alot!

Also, there's an FAQ linked in the first post of this thread which covers many topics, including sample settings from various people.

Regards,

Anyone still watching this thread that has it, could you toss the service manual up online somewhere? Mega Upload is dead.

Hey guys, I have a 82837 and I noticed one small white dot on the left side of the screen that doesn't go away until the lamp is done cooling down. Is the screen dirty or is the projector starting to go bad? Thanks!

I am sorry to tell you this, but there is a known issue with Mits DLP Light Engines that start out with little spots like that, then grow to to more and more spots until the picture becomes unwatchable. It happened to our 65736 (2008) and required a Light Engine replacement. The tech knew the symptoms all too well, and Google searches revealed many similar cases.

We had extended warranty from DTVExpress / Bankers Warranty, but they screwed us with a ridiculously low-balled cash replacement. Mitsubishi Customer Service helped out with a refurb'ed part, but it was still quite expensive for us.

I haven't watched this thread in ages and just happened to look today. Maybe other regular members have more info.

I had the same problem and have had it fixed. Read posts 10488 - 10493. Hope your set is still in warranty.

Hey guys, I have been a lurker for a while now and have scoured this thread....I
My Mitsu is turning off automatically, it seems to happen mostly when first turning the tv on for the day. It will shut it self off roughly every few minutes.

This past weekend it was happening constantly making TV unwatchable. During the end of my warranty I called Mitsu and they sent out a repair guy who stated my lamp doors have become warped and he replaced them. The TV worked for a short time after the fix, but then started turning off again. Mitsu will no longer help me seeing the TV is 2 years old, regardless of this being an ongoing documented problem.

I noticed others have had the same issue, and wanted to see if any resolution has been found for this problem. I do not want to get rid of the TV because when it is working it is beautiful. Let me know if you guys have any thoughts.

Thanks

the lamp door presses a button down when its closed. it prevents the TV from turning on when its not pressed. find a way to keep that button held down. if that fixes the problem you no that's the issue. find a way to rig it. there's also a temperature sensor in the set that may be acting up and may need to be relocated if its an older model. say 2007 era.

Seems to me it's overheating if the door warps, is the fan working?

It seems that sometimes I hear a snap type sound coming from my tv area. (hard to explain) It's not like a pop of the bulb (still working) sounds more like it's coming from the cabinet.. and I've heard the sound once in awhile since i've had the wd60-c9.. (couple of yrs) Wondering if anybody else had this quirk and if it means anything. Set works great.. thanks

This is just expansion or contraction of the plastic. You will pretty much hear this on any modern DLP rear projector. I have or had at one time Sammies, HP's and Mitsubishis in various sizes and from 2006 model years to the present and every one of them do it to some extent. I think my 2009 82" Mits did it the least. My 65" HP the most and the 2011 92" somewhere in the middle.

Yep, I've noticed that over the nearly 3 years w/ my 73737. It's very random but everything seems to be working fine- except for the two smudges on the screen. It looks like sunlight but it's not. The light engine was replaced two years ago because of this but it's been back for a while. The good thing is that it's only visible when the TV is off & the lights are on. It's under warranty through CPS but I don't know if it's worth the hassle.

If you see the smudges when the TV is turned off and the room lights are on, it is not the engine. It can be reflections of the room lights that will shine through the screen to the mirror and then back again or there might be some body oils on the screen or dust on the back side of the screen. However light engine problems show up only if the TV is turned on, now while it is turned off.

I've had almost no problems with my 65737 for about a year and half.

I went away for a long weekend, I come home and now nothing is projecting. It turns on, the light is green, but nothing ever pops up on the screen, no mitsu logo, nothing. It doesn't looking like much is going on when I opened up the side and looked.

Any ideas?

Have you tried resetting the bulb? Remove it, and place it back in?

I just tried doing that. It didn't work, green light flashed for about 10-15 seconds, then goes solid, but still nothing. BTW I can hear the color wheel spinning up.

Would a bulb just burn out without any warning? It's just weird that it wasn't being used or anything before it went.
