Anybody have any long term experience w/ this one? It seems to be, by far, the least expensive 720 pj out there w/ lens shift & would be ideal for my situation.
I've seen some rather good reviews & read the "feedback" on projectorcentral, but just wanted to see if anyone here had anything to add.....search didn't give me much.

I had the PJ-TX10 (Home-1) for a year and loved it... while it was working. The optical block degraded and left a blue haze all over the screen. But I got mine off eBay, so don't let that discourage the entire line. And the extended warranty through eBay paid off and I got most of my money back.

I would have bought the 100 as a replacement, except my room is so odd, that the throw would have resulted in an image larger than the area on my wall (would have had some spillover onto the ceiling).
Ended up going with a Z4 (more zoom and lens shift).

Audioholics gave it a good review. I'm interested as well, but to be honest the HD1000U is in the same price range, so I think I'm going to give that a shot first.

I've been looking at it also. I have a Hitachi RPTV and have been happy with it, and I think Hitachi has a good reputation.
It's a couple hundred dollars less than the H1000.
The issues I see are:
1. Contrast. One review tested a contrast ratio of 700:1. The AE900 tested at 1700:1 by comparison.
2. SDE. They talked about the sharp optics, but also the SDE.

It's not possible for me to preview any projectors (live in the middle of nowhere), so I have to rely on the opinions of the knowledgeable people here.

I'm in the same boat, judging like that worked out well for me with my first projector the Infocus 4805.

I just ordered the Infocus In72 off TD and took advantage of the 200 rebate running on it. I just noticed they have this projector for $699 and its 720p. I'm just not sure the 720p or higher is worth it until you get HD DVD and they are broadcasting more HD channels.

I sit about 12 feet away from the screen(130" screen) and had no issues with the 4805 and the 1080i HD looked awesome with it. If someone can convince me that the 720p Hitachi or Mitisubishi would be a big upgrade and worth the extra cost I would consider going that way as well over the IN72. For now I was going to hold out for the 1080p and blueray/hd-dvd etc. to get out there. Plus they need to start actually broadcasting TV in 1080p.

Looks like we have two topics with the same question running neck and neck...
http://www.avsforum.com/avs-vb/showthread.php?t=802610

My question is how does the Hitachi, being older, compare to the Mitz for about $150 more??? Probably a tough question, but has anyone been able to make a comparison??

The Hitachi PJTX-100 is a great deal and can be had for $699. 720P for $ 6-9-9 !!! Hitachi had some problems with their light engines in their rear projection TV's overheating and causing some damage to the panels. Newer panels are tougher and the problem has now been fixed according to the factory. They are not dumping projectors that won't last...they are undercutting the competition with a feature laden projector rather than a bare bones unit. No issues with positioning or throw range with the Hitachi. Superb optics. Back-lit remote.
5 pre-programmed modes and room for 4 saved memories. Very similar to Panasonic and Sanyo in this regard. The 1200 lumen output is ANSI lumens (it has a 150 watt bulb; the AE900U has a 130 watt bulb) and the 1200:1 contrast is ANSI contrast. Check out the projector at www.hitachi.us/

If in need of owner opinions, try www.projectorcentral.com and do a search under "Current Prices" by brand and model. 75 reviewers rated the Hitachi 4.8 out of 5. Their are dozens of 5 star reviews. For comparison, the AE900U, with 120 reviewers rated the Panny 4.6 out of 5. My own projector is a Panny AE900U. Wish it cost only $700.

I posted this in the other thread, but that one seems to be going away quickly.

For you owners/previous owners, can the PC input be used as a component input, and will this PJ allow horizontal adjustment to fill the screen on 2:35:1 AR movies?

Thanks

I just picked this one up too. I am rainbow sensitive and this looks like a heck of a deal!

Even though it is older, it still bested alot of the competition at the time.

Sounds good, and I totally agree. My thought is to buy this, and a good screen. Use the TX100 basically as a throw away for when 1080p is brighter and more reasonably priced.

OK... this is going to be my first projector.... Forgive my lack of knowledge here but the projector mount has three arms that extend out from the post mount. The projector has no holes in the top.... Is it mounted upside down when it hangs from the ceiling???

I very nearly purchased the Hitachi for the easier setup, but I settled on the HD1000U(it will arrive Thursday) because I've read of HDCP issues with the DVI input on the PJTX100. I plan on using the projector for both HD DVD and Blu-Ray, so that was a dealbreaker for me.

Has anyone here had any experience using the Hitachi with the new high def formats?

Blue-ray and hd-dvd will display 720p or 1080i over component- you only have to worry about 1080p over hdmi. This could change but it looks like the dvd companies are not going to enforce the copy protection and allow component out. Plus, I assume these are "late model" TX100s- it's possible that may not be an issue now.

As soon as my wife gets home tonight from work and I get the "ok" I'm ordering one tomorrow.

Where, exactly, did you order it for $599 (or is this a misquote)? I've seen it for $689, but nothing less..


This would be great for my brother.. It'll be tough finding a small (<=76" due to ambient light) Fixed Frame screen for him though (non-DIY, and below the price of the projector)

Good point SKoprowski, which is (probably) why Jason pm'd me. I'll have my brother check with them, but the only issue I see is that they don't offer an extended warranty (lamp or pj).

I guess folks like me on a budget should consider this projector.
Optoma has also dropped the price of the H31, so in the budget category it looks like the Hitachi, the IN72 and the H31.
Of those three, which would provide the best movie experience with standard dvd (480p) in a light controlled room with a 92" screen?
I'm thinking of color saturation and contrast (that includes shadow detail).
Would the higher resolution of the Hitachi offset the SDE inherent in LCD compared to DLP?
The Hitachi appears to have the highest lumen output. Is the difference significant?
Any advice would be appreciated.

Thanks

Hi jdfrietze.

Can you pls tell me more about your "blue haze" problem? I think I'm there too! I have PJ TX-100 with about 2,536hr on the clock. [yes, I'm on my second lamp]. Has worked like a dream since new. Awsome picture until the dreaded "blue haze" started from bottom-left corner of the screen [projector is upside-down, as its roof mounted] I'm about to hand it over to Hitachi Service Centre who suggested it might be Iris related; and if so, will most likely mean it will cost more to repair than replace. [ouch!] Good news is that I bought extended warranty to 5 years an so [I expect I] will be covered. I'd love to hear more about [what, where, when, how, etc.] your experience.

I''l know its exactly the same problem if you can tell me whether the "blue haze" replaces black colour projection when a TV/DVD etc. image is projected. So, on a white or light coloured part of the screen image it isfine. On a dark or black coloured part of the screen image, it comes out blue. [Is this bring back horrible memories?] Just to frustrate me even more, only 50% of the screen is effected [but its getting worse!!!] so on right of the screen it's perfect colours on the left hand side of the screen it sux.

Sure would welcome any [all] of your thoughts.
Thanks
