True, if they have been around for a while, I would say go for it.
I thought it was a new place.

Yes the projectorplace is very reputable. I've bought from them in the past. They are also an authorized Mitsubishi dealer and listed on Mitsu's site. http://www.mitsubishi-presentations....cii_sZip=62959

I bought my refurbished 3800 back in October from them for under a grand with no problems whatsoever. And I got a free lamp with it with the mail-in rebate. The refurb had 90 hours on the lamp and its been working flawlessy.
post #5824 of 6366
Thanks for all the responds guys.

Called them and asked for a quote. A rep gave me and that was it. No pressure or talked me in to buy it. Later I called back and made a purchase. It's already delivery.

One thing though, on their site still lists free lamp with HC3800 but it was expired long time ago. Well.

Can't say why there are light streaks or how the light path works in these projectors. I had sent mine in to Mitsubishi to get eh random shutdown issue repaired (turnover in a couple of days) and it came back with a faint white blob on the screen. The blob is only visible when there is no picture present. No shutdowns so far but not happy about the faint blob. I think these units are ULTRA sensitive to being opened and cleaned.

It sounds like you pulled hair, or dust or something backwards through the light path by vacuuming from the lamp housing area. You could try vacuuming from air exhaust and see if it pulls it back the other way.
post #5827 of 6366
When you guys vacuum on the outside, do you vacuum the intake AND exhaust vents? Thanks.
post #5828 of 6366
It seems to me if you vacuum the intake, you'd be pulling unfiltered air in thru the exhaust further contaminating the PJ.
post #5829 of 6366
I never vacuum the vents. The manual says to wipe the vents down.

Use a soft cloth to clean the projector and the ventilation grilles. When the grilles become dirty, wipe them with a soft cloth dampened with diluted mild detergent, and then wipe them with a dry cloth.

Received the pj yesterday. Been able played one movie to test it out last night. The color out-of the-box is nice but needs more calibration. Coming from Optoma hd180, HD20, and then Benq W1000+, its picture sharpness is far better than Benq 1000+ and a bit better than Optoma HD180 and HD20.

Very happy with the purchase.
post #5831 of 6366
AVS66, congrats and welcome to the club. The 3800 is a really nice projector. After calibration it only gets better.

Please help! On my Mitsubishi HC3800 failure-when you turn on the projector image is normally displayed for 10-15 seconds, and then shatters into black and white artifacts on any of the video inputs on the projector (I've tried everything). Tell me please what could this be? and what can be done?
Thanks

Unplug the AC power cable from the HC3800 (after it has powered down of course) for a few minutes. Plug back in and try.

If that doesn't work, Re-seat the lamp (take it out, put back in). Unlikely this will help according to your symptoms, but worth a try.

If no luck, you're gonna have to call Mits support.
post #5834 of 6366
fleaman,I tried all your recommendations but
unfortunately the error remained. I can not give Mits support my projector since I live in Russia and we do not have service support! Thanks for answers

Ouch.

When it first powers up (before it goes crazy), go into the menu and try the test screens (crosshatch, black, white), leave the test screens up. Do they go crazy after the 15 secs or do they stay in their normal test screen mode?
post #5836 of 6366
I'm always late with the choice of the menu.
INSTALLATION- TEST PATTERN- cross hatch, black, white
Too quickly the screen goes crazy

but if this is important I will try to adapt himself and catch
post #5838 of 6366
Hmmm.

Did you try the service menu?

Service menu: up/down/enter on the PJ at same time (not the remote).

It's been a while since I've been in there, but i think there's a master reset to factory defaults? be careful in there....if you get desperate to change anything, write down the default #'s first!
post #5839 of 6366
Why I like the pj very much, the remote is horrible. Half of the time not responding. I have to press buttons twice, sometimes three. Is it normal or I got a defective remote?

My remote works fine. Are you pointing it at the projector?
post #5841 of 6366
Having gone through a couple of HC3800's in the early days, I did notice that the remote on the first one had a stronger signal than the remote that came with the HC3800 I ended up with.

Of course, I'm not sure if it was a remote (sender) or receiver (HC3800 sensor or firmware) that caused this, but I do know that while I can still bounce the remotes signals off my screen to my PJ, now I have to aim very carefully (like a billiards bank shot). The first remote/hc3800 combo had a very strong signal/connection, I could aim anywhere on the screen, at any angle, and it would work. With the combo I have now, I just aim the remote at the HC3800 since it's too difficult to find the sweet bounce spot on the screen.

That being said, make sure you have fresh non-chargeable batteries in there. Even if they are new, try another new set. I've had a AA cell short out for no reason, while the AA cell next to it was fine (out of the same new package). And maybe even a AC pwr cord disconnect-reconnect to the HC3800 might help.

I have Vikuiti LCD Setup Guide cd which I got it free years ago. When I am happy with the image, can I use this cd to setup or it is only good for lcd pj?

Hi Tal. I'm interested on how you solved the problem.
Me too, just received the projectors back from the repair center, and I've several white blobs...

Fleaman - you da man.

I have been using Component for over a year - blu-ray to HC3800. I had an old HMDI to M1 (left over from my old infocus SP4805) with an M1 to HMDI converter to the HC3800 - never worked. I finally decided to get a true HDMI cable from monoprice and fish it thru the ceiling - but I had the same snowstorm thru the windshield effect with lost signal. I am so glad I checked the forum. The instructions you gave help me find the menu item for cable length setting I needed. OMG - finally have 1080p achieved.

Thank you and to everyone who posts.
post #5845 of 6366
You're velcome

1080p Hdmi is nice huh? When it works
post #5846 of 6366
For sure. I had started getting some of my favorite and "best rated" movies on blu-ray. They look so much better now.

I am glad I had a PVC pipe conduit (from projector to equipment) installed when I did my basement. I had a feeling I would want to snake the cables thru someday. Highly recommend that. I got a flat HDMI cable which was much easier to pull thru then that M1 cable. The HDMI flat cable I got was 25 feet from monoprice.

Thank you again. This made my weekend.
post #5847 of 6366
I haven't been on this in awhile so hopefully someone can help me. I've had my HC3800 for just a little over a year now. A couple of weeks ago, in the top right corner, some color blobs have shown up, kind of blue, redish, bit of yellow in there I think. It's shifted a bit to more of the corner and side. It's not a huge deal because when it's a dark scene or if a movie is not 16x9 then you can't see it but I wanted to know what's causing it.

My bulb life has been on for roughly 2700hrs on low mode and I read that you can get roughly 5,000hrs out of it so I was hoping that wasn't the case. I do have a spare bulb but I didn't want to just put it in and test it until I had some more info. Could there be something inside like a hair or something causing this? That might be stupid but I don't know. It just came out of nowhere.

Unfortunately I can't take a pic and show you guys right now because my girlfriend has my camera and she's in England. She'll be back on Friday but I figured I'd ask anyway to get the ball rolling. I know it's not the source since it does it on my cable, xbox, ps3, etc.

Any help would be greatly appreciated. I tried searching but didn't seem to come up with much. Hard to search for color blobs. Hopefully someone has some knowledge on this. I'd hate it to be a bigger issue than needs be.

Thanks again.

Not stupid. It could be a hair or dust bunny. You can (often) get color fringing around the edges of the hair or dust bunny, basically a form of chromatic aberration, though it's not from the actual lens, it's from the hair/dust.

Thanks for the quick reply. Do you know how to get rid of it? Do i have to take the bulb out to do it? Any help is greatly appreciated.
post #5850 of 6366
Unfortunately there may not be an easy solution.

Usually you have to send the PJ in to have it removed.

Otherwise you'd have to take the PJ apart, get to the lens/optic path area, and try to find/clean it. But you practically need a 'clean room' to do that, or you'll probably end up introducing more dust bunnys

Ironically many will get a PJ back from service (for something else), and it will have a dust blob in the optic path, from the servicing.

What ever you do, never use an air canister duster, it will just blow thousands of dust particles everywhere

Can you see the hair/dust blob move/shake at all on the image? If so, that means it's seeing some of the cooling fan air and it might dislodge on it's own. Try running in high lamp (faster fan speed) for a while.

Usually hair/dust in the lamp area won't be visible on the screen like yours is. It has to be between the DLP chip and the lens assy. The lamp area is before the DLP chip. But there is no harm in checking. Even the act of taking the PJ down, turning it upright, lamp out, lamp in, back on ceiling, might dislodge the blob. You can also gently shake the PJ a little while you have it dismounted. But be warned, it's always possible you might end up with more dust blobs afterwards....
