I bought an mwave bulb. It works, though I'll never manage to get it back out of the projector without damage (it's stuck in there real good) and I could never manage to calibrate the thing to get skin tones to look decent after installation. I think the new bulb or reflector are bluer than the original.

That and the fact that the projector stopped accepting signal from the remote indicated to me that it was time for a new projector.

I tried 2 of them. The 1st one was much dimmer than an OEM lamp with about 1000 hours on it. The 2nd one was worse than the 1st. I could barely see the screen! Both of these were only $79 or so but were the same ones others here had reported being quite happy with.
I will say that mwave was very good in taking them back and refunding my $$$ in both cases. They even provided a UPS prepaid label to return them.
Good luck!

Replacement projectors?

For those who are replacing their Pro 8100's, which projectors have caught your fancy?


Thanks,


Henry

I have had good luck with mine for over 2600 hours.

I believe that mgkdragn (Uncle Willie) has had similar experience.

Waiting for a 1080p 3D PJ. I haven't seen anything in the <$1,500 price point that can compare with the Pro8100.

In space, no one can hear you scream . . .

In for the re re re vitalization of the thread .. I have personally used 2 of the MWAVE lamps now with great luck, each slightly brighter than the VS lamps .. I have also installed 3 lamps in other folks units with great results ..


Currently, I have about 3000 hours on the last lamp, and the PJ itself has about 10,000 hours on it .. I've cleaned the filter once, I clean the lens about once a year .. I sold my spare unit for more than I paid but had to install it for the guy ..


Mine is still working flawlessly and with a well mastered BD, it still holds up well against the lower end new stuff that's out there .. and feature wise, it still can't be beat price wise considering what I paid ..


I just can't talk myself into any real compelling reason to ditch it and buy a current model of something .. if it ain't broke ..

Thanks Uncle Willie

Mine is still projecting a nice image with about 6000 hours on the projector and apprx. 3000 hours on the original bulb. I used another bulb from an internet source the other 3000 hours. There is no compelling reason for me to "upgrade" at this time. Just wondering what other owners are doing. My original question was about the bulbs available on mwave site. They have on at $149 and others at $105. Anyone know what the difference is? Considering buying one for a backup.


Thanks everybody.

Hey all, was just checking in, as it's been quite some time since I last posted... I'm up to 2000 hours on my MWave replacement lamp and about 6000 total hours on my projector, and it's going every bit as strong since the day I bought it. I've noticed less dimming on the MWave replacement than on my original, so I haven't had to recalibrate it as much either. Personally, at this rate, I've stopped looking at replacements. The reliability and image quality from the Pro8100 have been fantastic. In this day of throw away electronics, my Pro8100 still reigns as my center piece and the best single purchase I've ever made in AV gear!

I agree but I do remember it took several units before I got one that worked reliably and it had vertical banding that the timer fixes.

I have about 3,000 hours on my mwave bulb and still can't tell the difference between normal and economy mode. Took my original bulb out at 2,000 hours to have as spare. I guess Viewsonic got out of the home theater pj business.

Has anyone had their projector not power up? Normally there's a flashing green light indicating standby mode, but one belonging to a client of mine won't turn on and there's no flashing light.

He tested the outlet and it's fine. I'll replace the power cord but I doubt that's a problem.

Yea, mine did that once. I had to ship it back to Viewsonic for repair. They repaired and returned it in 4 days.

Long time, no see. Do you still have your Pro8100?

For those of you that weren't around at the beginning of the Pro8100, Meret created this thread that contains a treasure trove of Pro8100 info.

Yes he did and it was a great help to me when I was a Pro8100 newbie!

Yea, I do. It just got packed away in July during house renovations (we're moving later this year). It still looks and works like new. I am debating on upgrading to something newer next year but we'll see.

Thanks for the reply.

This one is out of warranty so I am going to take it to a local electronics repair shop.

Do you happen to know what failed and was repaired on yours? It might help the local shop pinpoint the problem.

Thanks

I'm still using mine. Same bulb for the last 4.5 years. Couple of movies per week on it.

(Same green dust blob for 4.5 years too )

sebberry, I had a small dust blob prior to replacing my bulb that I was able to get rid of it using a pancake air compressor with a blower nozzle and a straw to focus the blast. I did short blasts with the bulb out so there was no way to test whether it was effective until after wards, but sure enough, after replacing the bulb and powering up, the blob was gone!

Can you tell me where exactly you aimed the air with the lamp removed? I've had a small one that's only visible on a blank dark screen for a long time. Doesn't really bother me but like to know in case I get more.
Jeeze, I'd hate to blow air in there and end up with a screen full of 'em..........


Thanks!

I had the same fear initially, but it's unlikely you'll make it worse. Chances are that it was deposited there by the projectors internal cooling fan. There is no best route, as the light path hits several mirrors and lenses prior to passing through the lcd panels and hitting the prism and primary lens. I worked around the general area of the light path (direction lamp faces) with short blasts and I do recall you could feel the air come out the exhaust vent on the side of the PJ.

The main thing with any compressor is to make sure you've bled any water out first .. when I cleaned mine, I used an electric power blower, puts out more air than a can yet has no tank ..


You could probably rig an electric leaf blower to do the job ..
