Also, if anyone is nervous about swapping the housings just let me know. I am willing to post a "how to" with photos. It is fairly self explanatory but I know some people may be nervous.

That'd be great if you get time and don't mind.

Has anyone noticed a bit of play in the female connector inside the projector when replacing the bulb? I was trying to install an Mwave replacement last night and couldn't get it to fit. I'll try swapping the replacement to the original housing tonight. In my attempts, I notice that the female portion of the plug moves around quite a bit. Does everyone's do that?
post #9155 of 9206
can't honestly say that I noticed any play when I'm replaced mine but maybe to allow for any small misalignment between the connector on the bulb and the PJ.

I've replaced several in different units and never noticed .. although the MWAVE housing can require some force or slight modification in order to get it seated ..

I've yet to take my bulb out of my projector so I don't know. Often the connector inside will be a little use to allow for proper self-aligning of the contacts. I don't know if that's the case with the way the 8100 was designed.

I am sorry I haven't had time to post a "how to swap housings" pics.

In my opinion the aftermarket housing quality control seems to vary a lot. I strongly recommend swapping the bulb into the original OEM housing. It is easy to do and only takes a few minutes. Most of the horror stories we have read about are in reference to the housing not installing smoothly. Or worse, not being able to remove it. Swapping the bulb into the OEM housing solves this problem.

Since this lamp is used in some of the Mitsubishi PJ's, I've wondered if the housing design is just not fully compatible with the VS / Mitsu units ..

Sorry to ask as I know this is written in my manual somewhere; but do I have to remove the projector from the ceiling to replace a bulb?

Not if you have access to the side of the projector opposite the control buttons.

After a long fruitless attempt to get my cheap m-wave lamp to seat I finally broke down and took the projector apart to get the lamp in. I swapped housings with the original and that didn't solve my problem. So, I took off the cover. Luckily I didn't have to go much deeper than that. I did have to remove one exhaust duct to see the side of the lamp channel where the female portion of the plug is. The problem was that the plug was not shaped quite right and was getting hung up in one spot. I essentially had to tear off most of the plastic on the lamp portion of the plug in order to get it to mate with the projector side. Unfortunately, swapping housings does not change out the plugs, so if yours is bad you are going to have problems.

Luckily, after I put everything together the lamp seems to be working good. I'm going to give it some time before I re-calibrate the projector, but I'm happy.

hey guys smile.gif

i just put my theater back up for the winter. LOVING the image ! i think i am about 650 hours. though i do have 2 very dull dust blobs.
post #9167 of 9206
Has anybody had problems with their Pro8100 giving a “Lamp failure” blinking red light? My Pro8100 is about 3 years old, and the lamp is the original OEM one. I only have about 500 hours of usage on the projector. Sometimes if I let the projector go unused for a week or two, the first time I power it back up I will get that lamp failure. The solution is to unplug and plug the projector back in and try it over - that almost always “fixes” the problem. The bulb itself is bright and seems to be fine - it’s just that I get that failure occasionally…

Separately - any advice on blowing out a chunk of dust that’s somewhere inside the projector and distorting the picture? I’ve had a bit of dust mess the picture in the upper left hand corner since day one with the projector - as long as I am monkeying with it to take care of the “Lamp failure”, maybe I can get that dust out as well…

And finally - it looks like there isn’t any solution to the horizontal banding issue? I have the vertical banding handled via a timer that cuts the power to the projector each night, but I do have light horizontal banding as well - looks like that one is hopeless?

Thanks!
post #9168 of 9206
this thread is petering out. i wonder just how many are still using theirs ? i have no plans to replace it.
post #9169 of 9206
I don't think there was a fix for the HB. Mine has a slight case of it, nothing too distracting. I also have a single dust spot on the green panel somewhere in the bottom third of the image, but I've been putting up with it.

I have no plans to replace mine with something else yet. I've had it for 4-ish years, 900 hrs or so on the bulb and am still quite happy with it.

My only gripe is that dark scenes have always been a little too dark. Darker movies are a little hard to watch. I don't want to brighten the picture any more, daylight scenes are plenty bright and I don't want to start clipping the highlights.

Well they say it's the OEM bulb in a generic adapter. If true and even if the thing doesn't fit, you could transfer the bulb to your old one.
post #9172 of 9206
I'm gonna chance it. They offer a non oem too for cheaper, just concerned as I'm planning a big superbowl party and want to show off the projector at under 100h brightness . Hehehe

Best of luck. Be sure and let us know your results. Thanks!

Is your current bulb running on "Normal" or "Economy"?
post #9175 of 9206
Eco, but I did switch to normal from time to time.
post #9176 of 9206
Just thought it should be a little brighter on normal.

Wondering if anyone can help me out...

 

I've had this projector for about 2 years now. Been running on the original bulb with about 2300 hours and was looking to swap out for a new one. Tonight I tried putting in one that I picked up on MWAVE - only to find that after installing it all I would get is the Precision sign and then after a bit the projector would turn off.

 

I got a red light and a blinking red light - so assumed the lamp wasn't installing correctly. I fiddled with it a few times and thought I had it pushed in to the connector pretty well but still no luck.

 

After a few tries, I've taken out the new lamp/housing and reinstalled the original one just to see what was going on. The projector turns on fine but will only take me to the Precision screen without the display coming through. No matter how I switch the inputs, etc. nothing seems to come through.

 

Is it possible the lamp is still installed incorrectly? How do I remove the bulb from the new housing to install into the original housing?

 

The irony is that in the process, my two-year-old monoprice HDMI switcher has died - shows power but won't actually power on. I ended up plugging the HDMI cable directly into specific things to see if it would at least pick up the signal. At first, I got the Apple TV, but then could not get it going with my Xbox or Cable. Now, it's back to nothing but the default no-signal screen.

 

Any thoughts, advice, or suggestions?

 

Thanks a bunch!!

 

Kent

If I remember correctly the Pro8100 will turn off if it doesn't "sense" an input. Try to connect directly from a device, like a bluray player, to the Pro8100 using a known to be good HDMI cable.

Have you tried manually changing the source .. ?? Have you tried anything but HDMI .. ??
post #9180 of 9206

I have indeed tried changing the source both by remote and manually. I've also noticed that it doesn't work on either HDMI port no matter if I use my existing cables/switcher or use a fresh HDMI cable to plug in directly. I have a Wii hooked up composite as well and though it reads a signal it only displays a black screen.

 

I get a flashing amber sometimes when it's on - still wondering if the lamp just isn't seated in there correctly.

 

Hoping someone might have a clue and meanwhile I'll just keep fiddling!
