I hope it was VERY close to nothing.

This is a 7" electrostatic (ES) focus machine. Tube condition dictates how will it will focus and it will never focus even close to as well as an 8" electromagnetic (EM) machine. It will not fully resolve either 1080i or 720p, though 1080i is the best to run it in due to the lower bandwidth.

These machines were somewhat popular in home theater circles when the best digital projectors were horrid LCDs like the early Sonys costing $10,000 and the top CRT projectors where over $12,000. An ECP back then would go for a couple grand and be a bargain.

But times have changed. The only things it will do better than something like the HD7100 is absolute black level and on/off CR. Personally, I would not hang one of these today as the availability both in the CRT and digital world of projectors costing under $1000 (or even under $800) that are vastly superior.

I'm using an HD7100 with a Lumagen scaler. I have some occassional tearing issues when outputing 720p/72 or 720p/48. 720p/60 always yields perfect results. I'm not sure what the issue is and if I can get perfect 720p/72 100% of the time.

You have to have your HD3000 "unlocked" to be able to output 72Hz. See this thread for details.

One thing to bear in mind is the downscaling is a relatively simple to effectively implement function (much easier that upscaling). I'm not familiar with the HD3000, but I doubt it will accept 1080p/60. If it accepts 1080p/24, that is your best bet--period. If it does not, than you have likely two choices:1080i/60 or 720p/60. If the HD3000 has a good film-mode deinterlacer, than 1080i/60 would most likely be the best. However, given that downscaling is easy, outputting 720p/60 from the player will either yield extremely similar or exact results.

As far as getting the frame rate correct, if the scaler correctly handles the 3:2 factoring in drop frames, etc, then conversion from 60 to 72 should be similar or identical to 24 to 72 (the 24 to 72 is just so much easier because there is not "thinking" to do).

picked it up for 100 pecos(translated $). Except for its size I thought it would be fun to play with. Has less than 2000 hours on it. Has been sitting for a while. Thought I'd take the chance. There are also a couple of Kloss Novabeams available dirt cheap but not sure about these. I have the 7100 with the 3000 scaler I'm very happy with but decided another toy would be OK to play with. Didn't go with the Runco cause they wanted too much money for it.

Thanks for the info. It's not 'unlocked', but I thought that was only to enable 1080p... I guess I am stuck with 720p60 output only.

The unit has the Gennum GF9350 VXP video processor chip, and is billed in the manual as having "Studio-grade 480i/576i Standard Definition de-interlacing and 1080i High Definition de-interlacing." but this came out ~2 years ago so not sure how that compares with today's HW. The manual says it only accepts up to 1080i...

In addition to the Blu-ray player (leaning toward Samsung BD-P1500/2500), I'll be feeding HD content from an HD-DVR (Sony DHG-HDD250). I was hoping to get some definitive input as to whether there be much improvement if I use the HD3000 for de-interlacing/downscaling compared to just letting each of these units de-interlace 1080i and downscale to 720p.

If there is not much difference in the 1080i->720p performance, I still have to consider DVD playback since I have heard that DVD upscaling is not so good in many Blu-ray players. I assume the HD3000 will maximize the quality of that output as well if I just use 480i/480p mode from the player. I also want the best upscaling from the component out of my 400-disc Sony DVD changer.

FYI, I'll be feeding everything into an Onkyo TX-SR606 receiver for switching and HDMI conversion and then either direct to the projector or via the HD3000.

Do not get these, they are video only (i.e. 480i only).

Sam Runco originally made is living by painting things black and slapping a name plate on other peoples products (not a bad for making money if you can charge $4000 for a $10 paint job and $3 name plate!). As such the vast majority of the Runco CRTs are either NEC or Barco CRTs. What was the model number of the Runco?

HD3000 accepts 1080p@60hz. I will try 24 fps and will report back soon.

A runco DTV-947 is rebadged Barco 708 from previous post. Guy wanted a Grand.
post #2619 of 2851
I am at 560 hours and no problems for now (I am crossing my fingers) the false starts was solved for me by remaining the pj connected and powering the source after the pj put the "black source searching" screen (in my case a pc), no flickering for now...I hope that anyone can solve his problems
I can say that if I would not pay it really low considering features and quality (top notch for the 720p sector), I would never buy a "lucky pj" at normal price...

I saw a comparison with others PJ some weeks agò, and this Pj would do a good impression also with good and very good 1080p dlp (I saw planar 8130 and Benq W1000) but the epson tw5000 and jvc are way superior in all terms...

must be crazy. picked up my second torus today 78". Now I own a 60" and 72" as well. Came upon this accidentily trying to google info on CRT projectors.

Too much money by about $400.

I bought an HD7300 ~1 year ago and have finally gotten the media room setup. I mounted the PJ and fired up a movie last night for the kids. However, today when setting up the 7.1 systems the PJ wasn't showing anything from the receiver (Onkyo TX-SR606 with HDMI out) during setup, and then I heard a pop and then nothing else from the PJ.

There is no blue light even though the power is good (tries several outlets). I even tried installing a spare bulb I got with the PJ, but no luck.

Does anyone have any advice? This is pretty disheartening since I have < 20 hours on the PJ so far....
post #2623 of 2851
pcbrew,
I would contact Optoma asap. Your pj should have about 2 more years of warranty.
Good luck.
post #2624 of 2851
Thanks. I emailed them just before posting but was hoping there might be some magic cure. I had just mounted it in the HT room we just finished when it went out so this was a big downer on Saturday. They responded today and with an RMA form and said it needed to come back home for a few days.

Looks like I won't be watching the Texas Tech/OU game on the big screen after all.

Can you confirm the warranty is for 3 years? They did not mention whether it was covered or not so I just emailed back asking about that.
post #2625 of 2851
I only had 2 incidents with this projector to date. The first time I turned it on and attempted to adjust the feet on the unit. A momentary loss of power resulted so I don't
attempt any movement once I power It on . The other time I tried another scaler through the vga input which resulted in the overtemp light coming onwhile sequencing through it's inputs. Don't know whether these were just quarks but I pretty much don't experiment with trying out other equipment and stay with my routine of placing most inputs through the 3000 and religiously power up with all equipment off until I get the Logo then I turn on the other units. Powering down while the bulb is cooling I shutdown all connected equipment.
Since I have my unit table mounted. I listen to the slight whine in the balast during starup. There's an initial whine and a 2nd whine just before the bulb strike, a momentary
dim flash followed shortly thereafter with the logo then the DVI search.
Then I know all is well so far.
post #2626 of 2851
pcbrew,
Yes, the standard warranty for the HD7300 is 3 years. The lamp is not included in the 3 year warranty.
However, the issue you described looks like power supply failure and your pj should be ok after repair.
post #2627 of 2851
Thanks for the info on the failure mode.
I just got the RMA paperwork from Optoma so I'll be sending the unit out soon.
post #2628 of 2851
One other thing I forgot to mention is that after the logo appears then I power up all the connected sources.

This is exactly what I do and it is always on DVI I never use any other input (as the DVI input is fed from my Lumagen scaler). It is a bit of a pain because I can't have the PJ in my remote's start up macros, but I'll live. Over 6 months of use so far and no incidents (knock on wood).
post #2630 of 2851
PCBrew, did you get your projector back? I'm curious which configuration you ended up going with for your Blu-ray player. My HD-DVD player is basically a paper weight at this point, so I'll be picking up a Blu-ray player after Xmas. I've been 100% satisfied with the picture when outputting 1080i from the HD-DVD player (HD-A2) and letting the HD3000 down convert to 720p/60hz. The HD-A2 doesn't output 1080p, so I've never been able to test 1080p. I was hoping to be able to feed the HD3000 1080p/24 from the Blu-ray player but no-one seems to know if that's actually supported.

Let us know how things worked out.

If your HD3000 is a "locked" one then it won't take 1080p. If it has been unlocked, or was the unrestricted model, I think to remember that someone posted that through firmware update his unit could accept 1080p 24Hz. However, I have never, ever seen a fw update at Optoma's site.
You may wish to do a search in this thread. Pls. let us know if you find something.
Good luck.

Hey all,
Been awhile since I've been on, but just wanted to let you know the panasonic bd35 i recently acquired does connect to the 3000 scaler and is auto detected at 1080p 60hz through the hdmi connection. It is better than 1080I picture quality. My hd3000 is also the standard locked unit. I tried to switch the player to 24 but it would not.......not supported.
Peace
post #2633 of 2851
For those with an HD7100 (without the scaler), I'm using mine with a lumagen. I input 1080p/24 from BD and HD DVD and the scaler outputs a frame rate locked 720p/72 and it looks great. The scaler also performs the vertical stretch for CIH as well as image quality tweaks (this PJ crushes black, but the Lumagen allows a parametric grayscale tweaking that has let me pull the PJ out of black a little faster without disturbing the whole gamma curve and making the image look washed out).

Eric770,
This is great news because the HD3000 manual says (pg. 55) that it accepts as input 1080i at 60Hz and my own experience corroborates that; no 1080p input.
What is the fw version of your Hd3000?
Cheers.

Hope this helps, I definitely am enjoying the view.
post #2636 of 2851
Has anyone had problems getting HDMI signals recognized by their HD3000? None of the HDMI equipment that I have is detected by the unit! My PC, my new Dishnetwork VIP722 DVR, nor my DVD player will be detected. The PC and DVR both output at 720p and the DVD at 480i.
post #2637 of 2851
Have you tried to reset your hd3000 back to default settings.....maybe the timing or sync is out of whack....worth a try.

No I have not. Thanks for the tip; I'll give it a try when I get home.

I'm a bit hesitant on sending the unit in for RMA with some of the terrible stories which people have had with Optoma and their HD3000s(though I did send in my projector without problem)

Temporary use a short cable.. if solved you know it is the cable.
I have never had that issue since I switched to bluejean twisted pair 35'. Never have had false start either no matter what the sequence.

The cables from the HD3000 to the projector is fine & am not have issues with false starts. I cannot get the HD3000 to recognize sources connected to it via HDMI. I am using a 3' HDMI cables.
