It's enough of an issue to make me nervous considering how random it may be and how you are essentially screwed if it happens after the warranty is out.

the part is expensive.. make sure you allways clean the filter and make sure your room is cool.

Good advice, however, I cleaned the air filter every 30 days and it was always in a well cooled room. In fact, many times, when I cleaned the filter it wasnt even a little dirty.

IMHO, there is a flaw somewhere (either design or implementation) as I have not had similar issues with other brands.

The optical block contains the 3 LCOS chips, correct?

I've read (a while ago) that LCOS chips aren't as durable with heat (compared to say DLP) and it was one of the reasons earlier model LCOS PJ's weren't that bright (lower watt lamps).

Now that the newer JVC's are much brighter, makes me even more nervous. Especially after counting a good 6 separate AVS members in the last 2 pgs that posted about their optical blocks going bad.

More light leaving the pj with the same power input (I don't believe the lamp power has increased) means that if anything the pj runs cooler.

Could be.

How are they increasing light output?

And what's your opinion on the optical block issues?

With the current layout they removed a folding mirror, good for ~5% more light.

I believe they changed filtering also, for more usable light at D65.

Can you explain/elaborate why?

I assume you should be able to, being your screen name is JVC Tech!

I have 1500 hours on my lamp and want to get a replacement bulb and keep this as a spare. Looks to be a $80 price delta (ish) between the lamp module and getting lamp and housing together. Anyone installed the lamp module in to their existing housing?

My pic is still plenty bright, thank you high power screen, but just want to be prepared...

I have a concern about the JVC HD350 projector. I got one last week because I wanted to go from 720p to 1080p. I was using a a Marantz 12s series projector,720p output..I installed then installed the jvc hd350 and man I was suprized..now bear in mind the jvc had only 124 hours on the lamp clock,which means still bright right..WRONG..the picture looks soft..washed out,,,not crisp,,,the Marantz blows it away.and the specs on the Marantz camera is about half of the JVC..everything is set correctly,I had to use the high output on the lamp to even get a watchable picture,,what could be wrong..? I have heard folks on this tread state they use normal setting,if I did that I couldn't even see the picture..please help....can't even put the Marantz back up..I sold it.please any advice here.

Going from DLP to LCOS is a big change.
Softness/Not as crisp: 3 chip LCOS will not look as sharp as your 1 chip DLP ... especially a Marantz DLP (excellent, sharp lens). Also, the 720p lower resolution will give an added sense of sharpness (at the expense of screen door effects)

Washed Out: If you have a very dark home theater (dark walls, ceilings, floor) which prevents room reflections, you may be missing the higher ANSI contrast of your old DLP projector when viewing bright scenes. However, with darker scenes, the RS10 should look better than the Marantz DLP due to its far superior on/off contrast abilities.

My RS10 is much softer than my old 1080p DLP Sharp 20k. However, my RS10 is WAY brighter and has noticeably better On/Off contrast in dark scenes. I don't have good reflection control in my room, so I don't notice any difference in ANSI contrast. Are you certain the bulb only has 124 hours on it? The RS10 should be noticeably brighter than your old Marantz 12s

Hey Ed. Thanks for the help..my room is lite green, white ceiling, camel color carpet. I was totally shocked at the differance between the Marantz 720 p and the JVC 1080 p lite output. I just purchased a light meter off eBay. I am going to check the lite output of the projector..what should the lumens be with the bulb at 125 hrs. I am thinking the guy I purchased from reset the lamp clock..can't trust anyone today. Also could you point me to a place where I can get a step by step on doing the correct output measurements on this projector..I would be surprised if this bulb isn't at 1500 hrs..but without checking the measurements I can't prove it..so tell me how to do it...lol...about what should the measurement be at 125hrs of clocks time.. I am about 15 to 16 ft from my elite 100" screen..I am also using a DVDO VP50 with the projector.couldmthis be a problem ? Worked beautifully with the Marantz 12s PJ..kinda wish I had keep the Marantz ..but I sold it to a guy in the UK..the JVC appears to be in perfect condition..cab is perfect..no dust scratches ,,lense is perfect,everything works flawlessly.even the remote is super clean.can you point me in the right direction ? Or is this the nature of the JVC..like I said my old Maramtz would blow this PJ out of the water...help Ed.......Larry

I purchased on last spring from BB a floor sample When i got it set up same issue very dark and soft. I put in a new bulb and it is terrific. So my guess based on your info that either the bulb was bad or The lamp hours were reset by the seller. Just my evil .02 Bet a new bulb would solve your issues. I have white walls and beige carpet and I think my pic on this unit is amazing. yes the jvc is a little soft but still great to me.

The JVC is definitely a different image than the Marantz, but the JVC with only 120 hours on the bulb should be much brighter than your Marantz with an old bulb. So it sounds like you definitely have a brightness issue.

My guess is that your bulb has a lot more than 125 hours on it. Personally, I'd probably just go buy another bulb (it never hurts to have a backup)

You also might want to check out this thread ...

Some people have significantly increased brightness by cleaning some of the internal parts. I haven't encountered any brightness issues, so I don't have any direct experience.

I only know of the whole package about $300 to $389 and llike the fellow said a good cleaning of the intterior of the lamp case on the pj will also help but your proboem ill bet is a bulb with a lot of hours. Good luck let us know how you make out. The instructions for cleaning are somewhere on the thread i just do not remember where

Sorry, I don't have a light meter, so I wouldn't know. You might want to wait for the new bulb before spending time with the light meter. The brightness difference between my Sharp 20k (max contrast) and the RS10 (max contrast) was huge.

Art at projector reviews had over 700 lumens, calibrated, on his.
http://www.projectorreviews.com/jvc/...nce.php#bright

I would expect half that at 1500 hours but others can chime in as I have not tested mine at 1500 hours. Anyone just bought a bare bulb and added to their original housing?

I bought a HD350 of ebay and had similar problem. The bulb had 1200h but it was simply too dark. It turns out the glass covering the lamp was shattered also. There are other things to look out for. There's a thread that explains how to clean the part in the projector where the lamp resides. Sometimes it will be covered in dust and the image will be very dark. Don't remember the thread name.
I bought an original new lamp to replace and it is much better although for my taste still a bit too dark. I have white walls and ceiling and my former projector was a Benq W6000, a light torch. Blacks are no match though.

Hey folks,, I installed the new bulb, and man nite and day,, it's super bright, now I have 3 extra bulbs, I think I will let 2 go at a great price, I will keep one for a spare, I also cleaned the inner lense, made a heck of a differance. I think the fair price would be 125.00 per bulb. And 10.00!shipping. I am in the USA, so I will double box them if you want one or both. Pm me if you would like them thanks for all your help with this hd350.
