Mitsubishi HC6800 LCD HD Projector (30,000:1 on/off) - Page 37

I was careless and my vacuum cleaner sucked in, and broke, the foam portion (gray) of my filter. Mitsu won't ship overseas, as I am located in Puerto Rico, and it could take a little long to get a replacement. Is there something with similar porosity that I may able to use. I know this is critical as I don't want to get any dust blubs inside the PJ.

BTW, I am also looking for a lens cover that I lost.

thks...

thks...

I wonder if a regular a/c foam filter cut to measure will do the trick?? I hate to wait for delivery of a new one. However, potential dust blobs concerns me.

Anyone has the number for the parts department...I still need a filter and a lens cover...emailed to Mitsu from their web page but no reply so far.

In case anyone needs this in the future, I contact Mitsu Parts @ 888-307-8404. They emailed an order form which I them faxed them....

p/n for filter is 761B504010 FOR $23.35
P/N FOR LENS CAP IS 761b535010 for $10.62

Just double check the parts # with Mitsu Tech Support @ 888-307-0309

BTW. I just got a JVC HD250, and that makes my HC6800 available is someone is interested...PM me...

Just to clarify, the P/N for the filter was provided by Mitsu tech support but apparently was incorrect...the box arrived and it indicates it is for the HC-5500/6000, so the housing won't fit the 6800. Although the elements fisically fit the 6800 housing, Mitsu tech support won't confirm if the specs of the elements will suit the 6800, although it looks it may. I will probably return it...the lens cap is ok.....

Upon further checking, I was able to confirm that the filter elements looks indentical to the original one. Mitsubishi told me to keep them, but credited my account, since it appeared was too expensive for them to pay return shipping and ship another set. So for all practical purposes got them for free...Installed them, and working beautifully....

Is anyone alive on this thread!!!...Remeber..I have an excellent condition, Mitsu HC6800 available for sale for anyone interested..just PM me

How do you find the JVC compared to the Mitsubishi? Much brighter, image quality etc? Would be interested to hear your thoughts. I have about 400 hours on my HC 6800 and on my 145 inch scope screen the image is still awesome in low lamp mode. It's fully light controlled however. It washes out considerably with lights on. I will probably be looking for an LED model at upgrade time. May be a few years down tbe track.

Its more brighter, better contrast and black levels. The mitsu throws a very good picture with good material, that's what I have found out...for example I was watching the movie Hanna a few months ago and the picture was beatiful....King Kong beatiful picture quailty........on less quality material the better contrast of the JVC tends to help it with less than better material....on the other hand the JVC has a little more blur on NBA action, but it's ok...Overall, I would say that the JVC is an upgrade and a better PJ....list price was $3k for the DLA-HD250 when it came out..so it was a bit more expensive than the mitsu....

I still have the Mitsu but have'nt have the opportunity for a side by side......

For anyone interested in the Mitsu..send me a PM with a reasonable offer....Its in perfect condition..no issues at all...very reliable..only owner...

A note about Mitsu bulb life: The stated figures are not guarantees and usually include phrasing like "up to" a stated hour life.

That said I can report that the original lamp in my HC6500, part number VLT-HC7000LP, gave it up at 1824 hrs. of mixed low and standard usage. I use the higher "standard" setting more than not because I prefer the added pop in every picture.

When the lamp died it gave little if any warning - no image darkening, no picture degradation that I can say I noticed. As I'd imagine most of you are, I'm generally tuned for any perceived changes in how my setup is working but I got no signal. The projector simple turned itself off one night. It wasn't overheated or dirty - seemed completely normal until it mystified me in darkness.

I keep a spare and was back up with less than a ten minute intermission.

In every way I like this projector and can't imagine ever owning any other brand. I'm completely hooked on it's remote controls.

If you have a longer than 6' HDMI cable run it's a very good idea to use the extra sized cable with larger conductors than is normally used in the shorter cables. HDMI is very sensitive about factors like cable length loss/resistance and when it meets a transitory change when going from component to component the entire signal will need another try and you can exprerience odd losses. Monoprice has HDMI cables in pretty long lengths - the longer the thicker.

My 1st bulb lasted almost 3800 hours. The only problem was I was reading in the manual that if it did get to the 4000 hours limit, it would automatically stop working or something. Has anyone gotten past 4000 hours on their 6800?

Regarding bulb life, I have read that it also depends on the usage habits...for example..need to leave the projector cool down, don't turn if off/on within short time frame, clean the filter frecuently, don't use your PJ as you would your TV, ect...In my case, I use if from 2-4 hrs at a time, let it cool down, clean the filter frecuently...I also have the PJ connected to a UPS to provide clean power and in case of power failure to allow it to follow its cool down cycle, although never had the need due to power failure so far.......so far so good at about 1500 hours on low power....brightness is still great!!!

Mine is at 3814 hours right now. I always use low power. I never clean my filter although it is ceiling mounted, so I imagine that helps a little bit. (Cat fur doesn't help though!)

I am getting the warning message of death now, which I presume means that the PJ will stop once the lamp gets to 4000. So tonight I ordered a replacement lamp.

When you change the lamp check the filter to see how much dirty it is...That's against all odds..not cleaning the filter, since it will tend to restrict air flow and thus will run the projector at higher temp. I am curios to see how much dust your filter collected..

I replaced the lamp and cleaned the filter for the first time. Pic is below of the gray filter. The "black" edges are the non-dirty parts, and once cleaned with vacuum it was all that color again. The lamp had been running for 3908 hours, all on "Low".
With the cleaned filter, I noticed that the sound from the fan on the PJ was much lower. (Before it wasn't that high, but now it is again almost imperceptible.)

Are the dire warnings in the manual about replacing the lamp or it might blow up really true? My prior PJ, an HC3000U, still has the original lamp working since July 2006. I gave it to a friend after upgrading to the HC6800 for 1080p. They had to reset the lamp timer after 3000 hours, but that's all they've done. I'm not sure how long they have gone, probably 5000 hours by now.

I suppose the theory is that extended periods of high heat can eventually weaken the glass and increase the possibility (and I mean 'possibility' and not 'likelihood') that a catastrophic failure could result from overuse.

Methinks this is a case of a mfr being extra careful (and attending to all possibilities) to protect themselves from consumer lawsuits if the glass DID explode and injure someone.

Of course another reason a lamp can blow-up is that it was manufactured with a defect that was not spotted during inspection. So maybe the above disclaimer is an attempt to add possible "other reasons" for use in a court case. Hey, they wouldn't print that if it weren't true, would they?

WOW man you are lucky...with all that amount of dust on the filter the air flow should have been very restricted and thus cause overheating of the PJ...Lucky that your have lasted so long.......I cleaned my filter several times every few hundred hours but the level of dust was very minimal.....

Hi - is your Mitsubishi projector for sale?

Please let me know the details.

Is 4000 hours a year too much or too little?

I would say way too much...its more than 11 hrs/day...about 1,000 seems more reasonable estimate....unless you use the PJ to do all your TV viewing,,,,the latter is a good number...I have a flat panel on my family room to watcch regular TV, partiuclarly day time viewing.......If you got/buy a receiver with two HDMI outputs, which I still don't have, this may be an easy setup.

Is $850 for refurbs HC6800 worth for the money?
Or should spend $1500 for refurbs HD250.
Thank you.

I think the 6800 is the finest PJ I've owned, and I've owned four in the past ten years.

This PJ is bright, sharp, quiet, reasonable black levels, great menu and controls.

I have zero interest in 3D, and as this unit passes its third birthday, the only issue I have is where is the best place to purchase a replacement bulb that is an original MItsu product?

At $850 go for it

Do you have a picture of it? how much?

Sorry to bump a oldish thread... But i just got a 6800 refurb (paid more than i should have, didnt do enough research) my main whats making me nuts is that i can't get anything near a black on this thing, anything near black is green and not just a little green its WAY green. Just curious if this is a known issue or if i might have a defective unit.. If it is an issue can it be adjusted out and if so, point me in the right direction? thanks guys...

P.S. with Auto Iris on i can really see the picture adjusting light back and forth when scenes change, should this be less visable?

I didnt mention but this is replacing a hc3800, i thought it would be an upgrade but other than the powered zoom/shift and all that, so far the 3800 was better to my eyes.. I realize these are about 4 years old now.. is there anything around $1k that is much better? thanks again

A little bump for my question above if anyone still owns a hc6800:)

I had the mits 5500 and 6500. That doesn't sound right, it's likely defective. Can you return it?

For around 1K, you can get a low mile JVC RS2. If you go up to $1500, you can find JVC RS-40's and Epson 5010's, both will have a great PQ compared to the older mitsubishi LCD's. These projectors were not known for great black levels.

I have a 6800 and agree that it does not have the greatest black levels. More a very dark grey but still very good. What the 6800 does have is a beautiful film like image quality and a very quiet fan. Mine has about 1000 hrs on the lamp and still lights up a 145 inch scope screen with plenty of pop on low lamp setting. I have some screen shots on my thread. Its certainly not green. Good luck

Thanks guys.. and yeah loved my last 2 mitsu's. whats killing me is this Auto IRIS.. if they had a way to lock it at 5 and leave it there i think the blacks issue would have not been a issue:) The fan on this is actually louder than my hd1000 or hc3800, i emailed the poeple where i bought it (projectorpeople), and was told tech support would call me.. i dont know what they can do to quiet a fan over the phone though:) Will see.. Kept messing with colors and have it all out of whack now though. I need to learn to actually do this properly for once..

I've had the 6800 for two years now, and it is by far my favorite LCD projector (prefer over Mitsu 5000, Panny 2000). To my eyes, the blacks are good, but the picture overall is supurb (smooth, sharp, great color, bright).

I have my fan on regular and it is very quiet. The auto iris is OK, I have it at the lowest setting and I never see it working during an actual movie.

I plan to keep this baby in my theater for at least another 1-2 years.
