I have the blooming video issue. I have tried to get my light engine replaced twice. This is my experience to date.

1. Service repair company 1 - They would come out and take a look at it. If it needed repairing they would take it back to their company to repair (no repair in the home). Not only that but they confirmed that they ship the TV on its face instead of up right. Claimed they had been doing this for 20 years without problems (I didn't know DLP had been around that long ). I passed!!

2. Service repair company 2 - Came out and looked at it and claimed it was dust on the light engine and that Mits wouldn't replace it. Suggested I waited until my extended warranty kicked in because they would. Wanted to charge me $200.00 to clean the dust off. I passed!!

I can call another one. But, how do I get Mits to replace the light engine?

It is hard to get them to do anything, and very hard to get parts in a timely manner. I wish reps from Mitsusbishi would read this, because Mitsubishi customer service and customer satisfaction is among the worst I have ever experienced. Maybe it would be wise for ths USA to give these Asians a run for the American electronics dollar in affordable, but not cheap market. Mitsubishi makes garbage.

mnurse,

It is evident you have an axe to grind with Mits. This post has nothing to do with getting Mits to do anything and nothing to do with parts; it is about finding a service center dabhome feels comfortable with and his/her belief that it needs a new light engine. You have added nothing useful, informative or helpful.

I have no idea what you are talking about. Where did you read about this? Can you provide a link or explain what your problem is? What is your model#?

So both of these companies were Mits authorized service centers? What is your zip code?

1. They did not come out so they did not verify any problem you are having. As for the rest... strange...

2. I have told customers things at their home and heard them attempt to tell their spouse what I had said and it ALWAYS come out wrong. I ask the customer to let me explain it to the spouse.

Per this servicer who did visit you and saw your problem it sounds like you need a generic RP cleaning...

DLP light engines do not have light path cooling so the dust cannot be inside the light engine. It does have a lens and inside your cabinet is a mirror and they will collect dust and need to be cleaned to maintain peak image performance. This is not covered by ANY manufacturers warranty. Some extended warranties offer regular cleanings as part of the contract and you should always verify that your contract actually says that rather than believing what a sales person told you. Any rear projection design will need a cleaning at some point - some sooner than others, even under warranty, due to the environment the consumer is using it in! The manufacturer is not responsible for your unique environment and cleanliness.

Based on the information you provided neither Mits nor the extended warranty is going to replace your light engine - that is not your problem.

On AVS Forum. I have a MITS 65732. Here is a link of an image from an AVS forum member who had a similiar problem. My display looks similiar.

Yes. 48154

I figured why have them come out if they were going to transport the TV on it's face. Besides, I wanted the TV fixed in my home.

Maybe. But, is $200.00 reasonable for a routine cleaning? Besides based on the picture above do you believe it is due to dust?

I agree if it is a dust problem then it is my problem. However, based on many of the postings on AVS Forum, with similiar problems, I do not believe it is a dust problem. At this point, it seems like the only way to determine if this is dust or a light engine problem is to get the lens cleaned and see if the problem goes away.

I looked at the picture and it looks like a psychological test Without some background of what I am looking at it is meaningless. How about the AVS forum link discussing this?

Looked up your zip at the Mits consumer site - Oh My God - you have 19 service centers within 20 miles. Surely one or more of those can get it right. Shipping on the face makes no sense and could crack the mirror. It can be done but we would not take that risk (if we had to move one). Upright is how it is shipped from the factory to retail.

In home service will vary and should not be expected. An ASC is only obligated to either repair it in home or provide the labor and transportation for pick up and delivery. The reason for this varies from the philosophical to the practical. I do On-Site service but if I were in New York that would not be practical at all. As noted you have plenty of choice - see who will do it your way.

The price seems steep on the surface but I have not torn into one yet. Some products are straight forward and others require near complete disassembly. 1st and 2nd gen Mits is straight forward. We charge less than what you were quoted but prices vary with location due to the local economies. you have choice so I would call around, explain that you have a problem that will need a tech to look at it and one company already said it needs a cleaning and you would like to know how much they charge for that if their tech determines the same.

BTW, taking that Mits list and comparing it to the NESDA service centers for your area could be VERY helpful in finding quality.

At this point I am going with the cleaning until you give me more info about this blooming video. Tech wise, that is a CRT term that relates to the way that beast works. An FPD can't bloom! They can clip either burying blacks or turning variations of peak white into one solid form. Solarization is another FPD performance term...

Sorry, I thought it was obvious that there was a "glow" around the edge of the person that shouldn't be there. This happens with all images that are bright (such as white) on black. Over time it has been getting worse and worse.

The link is http://www.avsforum.com/avs-vb/showthre ... ost9939098. This is just one of many, but because he posted pictures which show the problem I used it.

I should have called it a blooming effect. You are correct it is not "truly" blooming.

At the top of that thread is a great symptom description of cleaning...

I've noticed lately that when white letters are shown against a black screen, the black becomes "lighter."

In other words, I don't see pure white against pure black.

The whiteness of white text or a white image spills over into the black background making it a very light black.

I've also noticed whiteness spill over when watching images from DVDs and Dish.

For example, someone's white shirt will create a spilling over of white into all adjacent surroundings and objects.

I looked at a series of images called Mits Aurora XX... Don't know why that the one you posted appeared weird yesterday but I get it today

It all smells like a cleaning. That is your next step.

I test for this using a high 100IRE and low 20IRE window. You can get these patterns from calibration DVDs. Watch the black around the white box at 20IRE, switch to 100IRE, the black should look the same. If it became brighter you need a cleaning!

You are probably right. However, this all started to happen 4 months after I got the TV. I certainly hope I don't have to have a cleaning every 4 months.

I have the DVE HD-DVD disk. It doesn't seem to have a 20IRE and 100IRE window, but it does have a 20%-80% pluge image. Of course as the white gets brighter. It spills out more into the black. It is not that the black gets lighter. It is that the white produces a "glow" or reflection into the black. Exactly, what blooming would look like.

I think you are right. At this point, I will have to get somebody out to do the cleaning and then if that doesn't help, it will be a clear cut case to replace the light engine.

dabhome,

I have the exact same tv as you, Mitsubishi WD-65732, and I am on my third light engine due to the blooming problem. This is a known problem with these sets, and the replacement light engines are supposed to not have the problem. I have had this light engine now for almost 6 months without any issues. Your best bet is to call Mitsubishi customer care and ask to be transferred to their level 2 support to actually talk to someone that has working knowledge of the set. I hope it works out for you and you will be amazed at the difference and the detail that you were missing when you get new light engine.
