Hey Fellow Mits DLP TV Owners!
Just thought I'd share my experience calling Mits about my WD-73833 (manufactured February, 2008) which will hopefully encourage anyone else with the issue to call. A few days ago I noticed at least 1 bright white pixel on the left side of the screen (there may be more than 1 stuck open pixel in a cluster as it is very noticeable but it could also just be one at this point). I took a closer look (always dangerous as you may see things you never noticed before) and I found 5-7 dark pixels (stuck closed).
After finding so many posts with the same problem and reading enough recent positive responses from Mitsubishi, I called them about the issue. It took about 10 minutes total. They offered their "good will" replacement program to me right away for replacing the DMD chip. As I've read, I would have to pay the negotiated replacement service of $200. I was sure to ask if this replacement actually was an improvement over the original. He told me that Mitsubishi had identified the issue and the replacement would never have this problem. Of course I know there's no guarantee but it was good to hear that anyway (true or not). My service call is schedule for Friday with a local service shop whom I've already spoken to. The guy at the shop who answered (who is not the tech who will be doing the replacement) wondered out loud what Mitsubishi would do if there was something wrong with the light engine. I told him I actually raised that question when it was clear to me that the replacement was for the DMD only (I read earlier posts in some forums stating that Mits was replacing the DMD and Light Engine but apparently not anymore - at least to start). Mits told me that if the tech determined there was something wrong with the light engine, then they would cover that too. I wonder how the tech would determine that. Does anyone who has gone through this know if there is some kind of test they can do to determine the health of the light engine?
Not sure if it's related or not but one problem I have had with this set over the last couple years is that on the energy savings setting for the bulb, the picture will eventually start to flicker. Under bulb warranty, I had the same service company come out and replace the bulb back in 2010 but about 6 months or so later, the flicker was back. The way around this is to set the bulb on the normal setting and it never flickers - it's just a bit brighter and I suppose will shorten the life of the bulb. Not sure if this is a reflection of a problem in the light engine circuitry or something else. Does anyone know?
Anyway, it was really very encouraged by the call. I told the Mits customer service guy that it's great that Mitsubishi has acknowledged the problem and started this program which encourages me to keep buying Mitsubishi products in the future. Of course thanks as always with these things goes to the early pioneers in the first year or so that had to suffer through what was most likely lack of acknowledgment of a real widespread design issue. Probably this explains a lot of the early negative posts I saw.
Anyway, I just wanted to pass this along. Hopefully the replacement and results go as smoothly.
