2007 Mitsubishi 732 series Owner's Thread (57732, 65732, 73732) - Page 87

I think what may have happened, as frequently happens with other products, sometime after initial introduction and broad acceptance, in subsequent production runs the manufacturer began squeezing the bill of materials. As a result I think later buyers may have purchased MITs TVs which had undergone some design changes ultimately resulting in these premature lamp failures that some have reported.

Quite the contrary with mine. My first lamp went out at approx 3500 hours and my 2nd lasted slightly longer. Both died from a melted mantel, having literally fried themselves from the intense heat. On my third lamp I noticed that the lamp vendor had replaced the filter screen with one having much larger holes in it, resulting in much improved air flow across the lamp and it never did burn out. I finally replaced it only because it was getting a little dark, though by that time it had 8177 hours on it, the mantel shows no signs of overheating and the lamp is still usable.

I received the notice of Class Action, but my WD65732 falls well outside the eligible qualifying purchase dates. (I bought mine in the Fall of 2006)

I have had zero service issues with it other than routine lamp replacement at what could only be classified as normal intervals. The only complaint I have with it is that it runs hotter than the dickens, producing A LOT of heat. Other than that it's been like the Energizer Bunny, just keeps going and going. Ours stays on (continuously) anywhere from 14 to 16 hours a day, every day for the past 5½ years. Ours is turned on around 5AM daily and stays on all day until typically 9 PM. Perhaps the lack of on/off/on/off cycles has contributed to its longevity. Whatever, we've been very pleased with our MITS.

If/When it ever dies we plan on replacing it with a more energy-efficient flat screen, but will try to stay with something about the same size (65").

So far no complaints....

As one of the beta testers for both the USRobotics top-of-the-line Courier "business class" modem as well as their consumer-grade "Sportster" I am reminded of the glowing review Consumer Reports gave "design rev 3" of the Sportster only to have replaced it with a substantially cheapened "rev 4" by the time the CR review hit the newstands. Rev 4 as some will recall was the piece of crap plagued by "Spiral Death Syndrome" where the modem constantly renegotiated the link speed lower and lower, ultimately settling in at 14,400k bps, less than half the advertised speed.

By comparison, the previous model (on which CR based their report) was a pretty decent little modem.

How many of these are still up & running?
My WD-65732 is still alive & well, approaching 6 years of ownership and so far the only thing I've had to do is replace an occasional lamp (and update the firmware to fix a Comcast CableCard issue). Waiting for it to die so I can justify something new. Wife wants one of the new Sammys

I too am on my 3rd lamp. I'd have to pull the set and look at the back to tell you when I last changed it, but we're presently approaching 22,000 total hours & no indications of any issues. I did a mod a couple yrs ago on the lamp module, completely removing the little filter screen (totally) and have not had a single lamp "failure" since though I can tell this one is aging because it's not as bright as it was when first changed. I also have a 4" muffin fan sitting next to the area of the cabinet (under left side of the base) where the lamp heat exhaust is located pulling the hot air away. I've been tempted to do the light engine teardown & lens cleaning, but since I have no problems with halos there's really no reason to. That plus I'd hear bitching from my wife about not being able to watch TV while it was scattered out on the dining room table. My chief complaint through all these years of ownership is that it just runs so blazing hot. Even with the fan on it, the discharge air coming out of it averages 112 degrees. (measured w/Taylor 9842 digital temp probe) I can't begin to imagine how hot it would be -without- the little fan.

I'm at the point where I'd really like to get something new, but really have not a single clue what to get. However, I don't want a 3D set because watching 3D gives me a splitting headache - (3D affects some people that way) of course now it's getting harder to find sets that aren't 3D capable, but I guess having a 3D set doesn't necessarily force you to watch in 3D. I'd like to stay at 65" screen size +/- 5 inches but have something that also isn't so dang bulky.
