Default WD-73734 Mitsubishi 73" DLP 1080p HDTV PROBLEM!!!

I have a WD-73734 Mitsubishi 73" DLP 1080p HDTV problem! I've had this TV for 2 years without having to replace the bulb once but just recently I started noticing black specks inside the screen. There was one at first than they're starting to appear all over. Could it be just dust inside the screen? Dead pixels? Should I replace the bulb? Please help!!!

I have a 57" Mits that was progressively was getting darker. It turned out to be the bulb was going out. Having specks appear on the screen almost sounds like dust on the bulb (Don't quote me on this). I would pull the bulb out of the back and inspect it. There is a lot of dust particles that flow near the bulb. That could be causing your specks. Otherwise, I would check http://www.mitsubishi-tv.com/ for a new bulb. They were actually the cheapest I could find and it comes in the new case and everything. Easy to install yourself. Let me know what you find. Good Luck!!!

Curse is right. There are a couple of screws and the whole unit pulls out. As long as you don't drop it on the floor, you should be fine.

Definitly not dead pixels. Did you put in a new bulb or same one? If you t.v. is still under warranty then you have that option. It sounds like dust though to me. I had a tiny, flying bug get inside my dlp mitsubishi one time, and could see it flying around the screen. Had to wait for the damn thing to die or escape.

more than likely its the mirrors in the DLP that are going out, eventually the specks will spread across the tv as the other mirrors begin to go out as well.

Yeah that's what my brother said as well...what should I do? My warranty is expired and the repair guy said I'm looking at at least $750 in repair...should I just sell this thing and buy a new TV? I really like this DLP and don't want to lose it but thinking about the repair cost I can buy a whole new LCD just smaller...

I put in a new bulb and my warranty expired...it's not bugs since the specks keep flickering as Tcan21 said I believe it's the mirrors...sadness

I'm in the same situation...instead of spending 500-700 in repairs I just bought a new LCD.

my warranty through Mitsubishi expired in November, but I just found out that since I paid with my AMEX card, they extended my warranty an extra year from the manufacturers warranty. So I may end up getting mine fixed for minimal to no charge at all, so I will give AMEX a call on Monday. So if you paid for yours with a credit card, you may wanna see if they have an extended warranty policy through that particular card company as well. Just another option.

I actually didn't pay with an AMEX card...I've decided I'm just going to save up and buy a 47" sony lcd...whats the point of repairing this DLP for so much when it's just going to get jacked up again 2 years later...?

Dang I hope this isn't a trend we just bought our first Mitsu 82'' diamond and its coming in a few weeks
Because it's easier to have courage from a safe distance away.

it looks like the OP had the DLP for two years before any trouble arose, which is the same case for myself

I think my bulb finally went on mine, I bought mine from Amazon on Nov 2007, It was used daily... No Tv in family room for a couple days. Luckily I bought a squaretrade warranty when I purchased it so the bulb should be covered

Is that about the lifespan of the bulbs on Mitsubishi's? cause the old 60'' sony rear projection tv my brother still uses for games has been running since 06.

We haven't even got our 82'' delivered yet and already I'm worried about that lol

I'm a little worried after reading thru this. I bought a MITSUBISHI 73" DLP WD73736 in April of 2009. Is there any more word of problems with these? I did notice a black speck at the very bottom center of my screen, but figured it was just dust. Hope it's not a major problem. I love the TV! Blu-rays look amazing on it and I really wouldn't trade it for anything.
