Official Mitsubishi WD XX833 Owners Thread - Page 117

Needing to replace a lamp with in a reasonable length of use is not considered a hiccup. This would be normal maintaince. Just like lamps and blubs in your home eventually will need replacements. 3000 hours is a little short but not really excessively so. I hear more about an average in the 5000 hour range. If this is accurate, it means 1/2 of the lamps fail before 5000 and 1/2 fail after.

Is there an explanation as to why I can't seem to change the keystone geometry for my HDMI input? The option is greyed out.

Has anyone experienced a problem where some of the controls on the remote either don't change settings on the set or work intermittently? I can't figure out if I have a problem with the remote or the TV receiving the commands, although I can use another remote to make changes. Yes, I changed batteries. Thanks.

I recently noticed the picture on my Mit 65833 was getting dimmer. I did some research and found what I'm sure you all already know, I guess that is what the bulbs do at the end of their lives. I've had this TV since December of 2007 so I have no complaints about the bulb life. In fact, other than the original calibration, I haven't done a thing to the TV. I plan to replace the bulb myself, but wonder if there aren't other maintenance items that should be done at this time?
I know that in the past when I had the lenses cleaned on my old Sony XBR rear projection it really brought the picture to life. Is there any cleaning or maintenance i should be considering at this time?
Should I have the TV calibrated again with the new bulb?
Also, any suggestions on replacement bulb? I don't mind paying a little more for peace of mind. Thanks for any suggestions. Steve.

From a post of mine over in another thread:

"I've had good results from Dynamic Lamps on Amazon: http://www.amazon.com/shops/dynamiclamps

Another poster here spoke very highly of Nio on eBay and they have high ratings: http://stores.ebay.com/neilampsandelectronics

In both cases you will find they sell clearly advertised-as-such Philips lamps, or Osram, as well as the cheaper Chinese no-name knockoffs. That is okay as long as they are clear with you what item you are getting and they ship that item.

In dealing with other sellers, beware of the term 'OEM equivalent', which does NOT mean 'OEM'. OEM-equivalent is a wishy-washy meaningless term. Another clue is the price, you will not get a genuine Philips or Osram bare lamp for less than $50.

Bare lamps might come with the pigtails and connector, or not. If the connector in your housing is in bad shape you should go for the housing + lamp."

Thanks Chuck, I ended up getting an Osram bulb and housing from Lamp Source. Could have paid less but feel the piece of mind of using the bulb Mitsubishi recommends and Lamp Sources warranty is well worth it. I plan on installing the bulb this weekend. We'll see how that goes. I'm still wondering about calibration and maintenance. Thanks, Steve.

Anyone interested in a 915P061010 Lamp Assy direct from Mitsubishi (a spare that I received for my WD-73833 at the time of purchase) should PM me with a best offer.  I was planning to E-Bay it but thought I would give AVS members looking for original OEM parts first crack.

 

EDIT:  Replacement lamp has been sold.  I'm entertaining chopping this baby up if anyone is looking for some spare parts?  I noticed that ShopJimmy is now selling the replacement DMD chip for $159 (wish they had it a year ago when the ants started marching in my screen!).  If anyone is interested in any components (e.g. the optical engine, DMD chip, PWB power supply board x2 or a what I believe to be the issue with my tv which is a defective PWB Main board) for spare parts then just PM me.  It will be going on Craigslist soon (Cleveland, OH area) in case anyone is interested in buying the whole TV for a modest amount?  If you can find the PWB main board anywhere or convince Mits to sell it to you (last price on ShopJimmy was around $150) then it's easy to replace and the DMD chip is only a year old.  I went a different upgrade path and no longer have space for the tv...great pic while it lasted though and my other TV is a Kuro.

Well. I just got my fist white dot today right in the MIDDLE of the picture. I've ordered the DMD for $159 at ShopJimmy and will do a thorough cleaning while I'm at it. I have just over 10300 hours on my set ( WD-65833 ) and just purchased my 3rd lamp at 9800 hours. Hopefully I can get another 3 or 4 years out of it before I am forced to buy a crappy LCD.

UPDATE:

Finally got the DMD. It took me about 90 minutes to install since I took a lot of time to clean the dust off the stuff I can't get to with the set assembled. Dust wasn't too bad on the DMD heatsink and Sirocco fan considering I never touched those until now -- 5 years later. My geometry was a little off ( about 1/8" tilt ) but was easy to fix in the geometry menu. The picture pretty-much looks brand new. I had 10467 hours on the set by the time I changed the DMD.

My white dots had grown to 5 and I also had a black dot too.

Hello All,

I know this is an 833 thread but I'm hoping one of you can help me out. I'm trying to check the hours on my 57831 and am having a hard time finding the info in the service menu. I checked it before but can't seem to find it once I'm in the menu.
Thanks in advance for any assistance!!

Press MENU-2-4-7-0 on the remote. Bulb hours will be shown in the lower left corner of the screen.

Beautiful. Thanks Amadeus!!!
