Default yet another unhappy customer

I have a 65" Mitsubishi I just started to see white dots a week ago it's the same thing as everyone else has experienced I call Mitsubishi
customer service and they are going to call me back in a day or so. I have had my TV for about 2 years. From what I have read it is the DLP chip there was a defective batch of chips that were installed in several TV manufactures TV’s. Reading all of the post this is a real problem that Mitsubishi has known about for a while now. I will let you know how it goes I know the chip is 299.95 if I was to buy it my self and install it. I wouldn’t recommend trying to install it you’re self unless you are a service technician.

I've had a Mitsubishi tv for a few years now and about 2 months ago, I noticed one white dot, the next day there were 3 and now the screen is covered in white dots. I just got off the phone with Mitsubishi and they said the chip that would have to be replaced would cost $150.00 which they agreed to pay for, however, I would be on the hook for the labor, $370.00. I complained about this because this has been a known problem and I should not have to pay for it. The guy put me on hold and came back and said they would pay for half the labor costs. I probably could have gotten them to pay for more even though they said that was the final offer. I just didn't feel like dealing with it anymore. So now I'm waiting for a service repairman to call to come out and fix it.

Default Another unhappy star gazer

We have had our 65" Mitsu. DlP for 3 years and 10 months, bought it 2/2008 at H.H. Gregg paid over $2,500 for this TV. I just replaced the lamp 3 weeks ago, exactly one week later we got our first white dot, now 14 days later we have over 150. I have researched and read all over the internet that this is apparently a big issue with this TV. We are going to contact Mitsu. and see what they will do if anything. I definitely want to be part of a class action suit if necessary. There is no doubt this is their problem, not ours. I will keep you all posted.

Afterwards, I called the repair shop and they confirmed that I will only owe $125 (of which I already paid $70 for the diagnostics trip).

Now, the repair shop will order the chip (which apparently is back-ordered due to heavy demand), then call me to set up a date to install.

So, looks promising. Will update as things progress.
Update - Jan 9

Received a call from Mits Cust Service on Jan 6, saying DMD chip was shipped to repair shop on 12/30 and received on Jan 6. They even supplied a UPS Tracking Number. Called repair shop today; they confirmed they had the chip.

Install is scheduled for Jan 16; still keeping fingers crossed, but I'm feeling reasonably confident it's going to get fixed.

I got lucky here.

Around October I noticed the little black spot on my screen. It almost looked like a chunk of dirt, but it wouldn't wipe off. Wondering if somehow something got inside, and wondering how to clean it, I stumbled across this thread.

Since October I have noticed more and more black spots, and now a couple of really irritating white spots on my screen. This thread held true: the problem gets progressively worse. I am now up to about 20 black spots and 3 white spots, though that doesn't sound nearly as bad as most members have posted.

I called ABC Warehouse where I purchased the set in Dec 2007 and was surprised to find out I got a 5-year warranty with it, not just 4. Yay!!

Techs should be calling within 24 hours to schedule an appointment, free of all charges. I will reply with the results, but I have to thank these forums for all the information that let me know what to expect from this problem.

Cheers!

Tech already called back, service call for the morning of the 12th. Excellent!

I have to agree with others in this thread, though. For $2200 I would expect a TV to be problem free for many, many years. I went into DLP knowing I would have to replace a bulb or two over its lifetime, but I didn't expect other problems. Heck, I still have a Fisher 25" CRT console TV from 1982 that works perfectly. You must love modern technology. Just like the Coleman cooler chest I purchased in the '70s that still holds ice for a week, compared to today's items where the hinges break off after a year. :-)

Still, I love my DLP, and I absolutely think it was the best bang-for-the-buck 5 years ago, when a 65" plasma or LCD was over $10,000 and had a very slow refresh rate. Now that they're more affordable, though, I won't opt for DLP again.

I also have the same issue with my Mitsubishi DLP. I thought I was reading my own story. It is 4 years old, I've replaced one bulb after 2 years and a couple of weeks ago I got my first white spot. Now their are about 7 with numerous black spots as well. Hopefully Mitsubishi will do something about it at least. I will post results as well. Very unhappy with an expensive tv at the time.

Tech was in and out in about 20 minutes. He replaced the DMD IC and cleaned the inside of the unit. Yay! No more spots!

He then told me I had to do a better job of keeping it clean -- just hit the back vents with a vacuum (don't blow!) once in awhile.

What has been been the best deal Mits is willing to do? part plus half of labor? Still seems like that would be around $200 dpending on the labor charge. I've seen the part for only $125-$150, and judging from the video another user posted on, i'm fairly confident i can do the replacement my self. I'm considering skipping calling them altogether unless someone has had any luck with them covering the entire replacement.

The original offer I got was Mits would pay for the part, and I would pay for all labor ($250). I told them that was unacceptable, and I offered splitting the labor, which they agreed to.
I already paid $70 for the initial diagnostics that Mits required, and the repair shop will apply that to the $125 labor, so it should only cost me an additional $55. Considering this is the first time I had any issues with the tv, I feel the cost is reasonable (under the circumstances).
I could definitely do it myself, but I've seen a few posts where there were some issues with the picture after the chip was replaced by DIY'ers, so I figure the peace of mind is worth $55. (plus I get a 90 day warranty from the repair shop on parts and labor)
Just my 2 cents...
