Bad news. The Osram lamp arrived this afternoon. Says Original Epson on the box, so I was hoping it was what I'd get from Epson themselves, but that's not the case (which I suspected anyway). If it were Epson there would have been the little tool to spring open the plate atop the PJ that reveals the lamp. No matter, as long as the lamp has a good Osram bulb I figured I was OK.

I remove the lamp and look at the filament from in front and I see that it's quite askew. It's not pointing straight out, perpendicular to the plate in front of it but is pointing to the side quite obviously. I look from the side and see that the bulb was positioned crooked. I'd estimate at least 5 degrees, maybe 7 degrees off the perpendicular. Rats!

I turn the lamp around some more and see that the little screen wasn't applied correctly. It's bunched up, doesn't fit into the slot it's supposed to be in. WTH! What was wrong with the person who assembled this thing?

I call Amazon and explain for 20 minutes to the CSR, who displays substandard competence, but I stuck it out. I suggest that they should investigate this seller who appears to be selling substandard, grey goods. I find it hard to believe that this seller specializing in lamps (Dynamic Lamps, Amazon 3rd party seller) wouldn't have taken a look at what they were sending a customer. Inconceivable. She says they'll look into this. Meantime, my return is being processed and expect to get another prepaid shipping label and I'll be returning my 2nd lamp in two weeks.

I imagine that it's probably possible to remove the bulb and reassemble the lamp so it's got the bulb/housing orientation correctly, but obviously I should have to engage in that kind of activity with this, I'll just return it. Many people obviously have chosen to just pony up ~$250 for the Epson lamp because of the problems people have had with cheaper lamps. If money is no object, obviously that's the way to go. Well, like I said, the ins and outs of projector bulbs is something I knew nothing about. I'm now once bitten, twice shy, twice bitten, fairly nervous.

So, I'm going to return this lamp. Meantime, at least I have that cheapie lamp which seems to be what it's purported to be and gives me a for-now decent image.

Dam! You spend more and you get worse quality. It could also be a manufacturing defect. Not every thing made is always perfect. But I understand that it should not have had all those issues. I'm gonna get the ebay one that you recommended and use that as my main bulb and keep the original one as a backup. Let's see how well it holds up.

Yeah, I think you're talking about the one from Electrified. They sell on Amazon too. I think at Amazon it's almost the same price, might be safer to get it there. I read a lot or all of the user reviews for the Electrified ELPLP49 lamps at Amazon yesterday. I think it's something of a crapshoot. Some people have great luck, others don't. I maybe got lucky with mine. I was certainly unlucky with the two more expensive lamps I bought over the last week or two, which happened to cost 4-5 times as much as the $22 Electrified one. One sent me the wrong lamp, the other sent me one that was badly assembled in a factory. This was no small manufacturing defect. I had a closer look today (will send it back with prepaid shipping label tomorrow). They left off one of the 4 tabs that hold the bulb in place in the housing. The net effect was that the bulb is tilted about 7 degrees off axis.

I did more searching today. I even called Epson and asked them if they would send me a "spare bulb," something they were including with this PJ back when I bought it. I was told that they did that because a lot of the buyers were experiencing premature bulb burnout due to inferior bulbs. Epson's response was to give people a spare bulb with the PJ and they also changed manufacturers of the bulbs they were supplying. He said it took them two years to do that, I thought I heard him say that.

He put me on hold and then told me that they wouldn't send me a replacement. I think the reason is that they figure I didn't have premature bulb burnout, although he never asked me how many hours are on my bulb. I wasn't going to plead or argue, I just thanked him and that was that.

I started doing more research. There was a "spare bulb" that looked authentic and unused for auction on Ebay but I didn't bite. Reason is, I'd just heard this Epson guy say they used to supply inferior bulbs. Why would I want to take a chance on one of their bulbs from years ago? This one was evidently from 2009.

This whole business of replacement bulbs for Epson PJs is a confusing mishmash.

I'm thinking this now -- I have that cheap bulb that seems alright now and it has a 150 day warranty. I think I'll continue to use it until I use up that 150 days. Meantime, I'll take my time in getting another bulb.

EDIT! I turned the projector back on after discovering the 2nd anomaly, the one that makes the image unwatchable and indeed, as I'd hoped, that didn't reoccur. Hmm. It's not the first time that I've had a weird thing happen with this Epson 8700ub that was "cured" by a restart.

Hmm. I'm wondering if there are some things I can do in terms of maintenance, some things that will/might improve the image and prevent or delay deterioration/damage. Obviously, an important one is to clean the filter (which I just did for the first time last week). But I wonder if there's something else. Replacing the lamp (when the time comes) with a reliable lamp could be critical (read the below!). I have seen post(s) declaring that a faulty lamp has melted, fouling the projector.
- - - -
Crucial update!

I have changed my mind. If I were to go back a few weeks, with the experience I have now, I'd hope to just bite the bullet and buy a bulb off of Epson!

The movie I watched to test the $22 from Electrified was 2.40.1, so it didn't reveal the entire screen. When I turned on my HDTV image source this weekend (the obligatory British Open golf tournament), I discovered that there was a band at the very top of the screen that was darker than the rest, very noticeably. I'm color blind (partially) so I'm not sure, but I think that band, which covers the top ~6% of the screen area) is pinkish in tone. It doesn't make the image unwatchable, however, and I had the projector on about 18 hours over the weekend. I figure that it's not the bulb doing this, but something that's amiss in the projector besides the bulb. But here's the thing: I think it could be because of the bulb, it might be running too hot. Or, possibly something happened when I replaced the old bulb, something that pushed something out of alignment. What it is and what caused it are unkown to me.

This morning I turn on the PJ because I want to make sure that dark horizontal bar is still there at the top before I remove all the cables and put in the old bulb and retest (I expected that to have no effect and that the bar would still be there). Instead I do see the bar but I also see that the top ~20% of the image is cut off entirely, shows as white with that darkened bar on top still there. Now the image truly is unwatchable! I tried a different source, same thing.

Where I go from here I don't know. I have to figure the PJ may be history. Maybe I can have it repaired economically, maybe there's something I can do to repair it. I turned it off, haven't turned it on again ... maybe at least the 2nd condition will disappear, however naturally I'm not optimistic.

I have to wonder if this series of events aren't caused by this new bulb running too hot. Can anyone speak to that? Is there any way to determine if it is running too hot? I didn't notice the fan being on more than usual but I watch my stuff with sound blocking earbuds in, so I might not notice. But I think I would have noticed the fan running a lot more somehow anyway.

The now persistent (i.e. first) non show-stopping anomaly:

I just got the $21 bulb delivered yesterday. It sure takes a while for the bulb to turn on vs the original bulb. Definitely not as bright. Living Room and Dynamic are the same brightness. The only thing that changes between the two are color temperatures from what I've seen. To me, Living Room is the same brightness that Theater mode would have given me if I had a brand new Epson bulb. But then again, I can't complain too much since this was only $21 bucks.

I'm gonna stick with it to see how long it'll last. I keeping the original Epson bulb in the box.

Edit- I haven't noticed any color banding on mine. But then again, I probably only put 1 hour on it so far.

I'm virtually positive that the band at the top isn't produced by the bulb. There's something going on with my PJ. I will tackle it this week. Well, it may be something I have no idea how to deal with, but I'll try. Anyway, the image isn't terrible. If I weren't color blind maybe it would bother me more. Does it look pink to you?

No, to me, the living room color temperature seems the best one to use with ECO off and Auto Iris on. On the OEM bulb I had those turned off. I also lowered the Color Temp to 65K instead of 75K. I also lowered Saturation to 0 from 5. This is just naked eye calibration. Not using a calibration discs. Bear in mind that I only use the projector for special occasions like if there was a good movie that I know I will like or any huge AAA games like God of War or Uncharted. Otherwise most my screen time is going to my Sony 940C TV.

I don't remember if this happened to the original bulb but is there supposed to be this much light bleed off to the side?

Yeah, I guess it's the same one as I got recently. Mine seems OK, but something went haywire when I installed it. I have a pink band at the top. Mostly I don't notice it, partly because I'm partially color blind. So, I'm living with it for the time being. I found a thread here where flocks of people get help with this or similar problem but I haven't taken the time to get deep into it. I will when I have the time. Meantime, it's get my garage in shape before it starts raining and other priorities before I get to this one!!!

Replacement Bulb

For anyone looking for a replacement bulb, I'm happy with this one I found on Amazon: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

I replaced an Epson bulb that had 1,500 hours on it. Using a smart phone light meter app, it appears that brightness increased by 100% compared to the old bulb. Replacing the old bulb also resolved an issue with a pink bar I had on the right hand side of the projected image.

Input lag

Hi guys, this forum has a fair amount of posts and I'm having problems sifting through. I'm looking for an official input lag rating (i.e. using a leo bodnar device is possible). I'm looking at several used 8700ubs (would get squaretrade warranty) to stay in budget for wife, but game maybe 30% of the time and I can't find any readings for input lag, what I have found to all over the place (40-80ms). Of course, I'm most concerned with readings with all the processing off that could be interfering (including the dynamic iris). Any help would be appreciated, this looks like a great projector (I don't need 3d)!

Thanks for the suggestion! I just ordered it and will give it a try. God of War for PS4 comes out next Friday and I want to play it using the big screen experience!

Although I don't know the input lag myself, I've been able to play MP games like Uncharted 4 with no problems and have come in 1st to 3rd place most times. Just turn off motion interpolation for the least amount of lag. Sorry for the late reply but I came here myself looking for a new bulb for God of War!

Hello everyone.

I have this projector for many years now and my bulb life is at 970 hours.

1. I wonder how much more to go.

2. Does the bulb blow up when it is about to die?

3. I still got the free 2nd bulb I have not use. I am afraid of dust getting into it. Whats a good way of exchange it out?

Thanks.

Hi,

1) I'm not sure, but a genuine lamp should last about 3000h. This may vary according to use on eco or normal mode, and also conditions external do the lamp.

2) Anyway, as the lamp gets used, it will dim and dim until it starts flickering. The "noise reduction" option on the menu is supposed to deal with the flickering to a certain extent. But once it starts flickering it's a good time to replace it. About bulbs exploding, that's not as common as people seem to think. If the bulb starts flickering and you keep using it for some time, it will most likely just burn out. Still, it's best to avoid letting it die inside the projector, just to be safe.

3) I don't understand your concern about the dust. Is the replacement bulb not stored inside a box? Is it just a bulb or the whole lamp assembly with plastic casing?

1. 3000 hr is good. Yes I have the genuine lamp.

2. OK, I will keep this in mind. Thanks.

3. I was reading about dust blob inside the compartment. Thats what I was thinking when I change the bulb. Perhaps change in a dust free environment? Where to find one? LOL

Dust blobs can occur when dusts sets in on the surface of the LCD panels, the polarizer filters or the backside of the lens. Usually, it's the projector's own ventilation system that leads dust in there. You have nothing to worry about when opening the lamp compartment to replace the lamp.

3) I don't understand your concern about the dust. Is the replacement bulb not stored inside a box? Is it just a bulb or the whole lamp assembly with plastic casing?
Hello.

My first original bulb finally died on me. It has 1125 hrs. It just keep getting dimmer & dimmer to the point it is not bright to enjoy. So tonight the machine start, but no light. So I replace it and this is my free bulb from the promo.

I bought it new on Jan 9, 2012 for $1400 after all the free gc and cc promo.

I put in about 3-4 hrs a week on the projector. I never start or stop, just on it until I shut it off.

Ok, 1125hrs is not much, but I've read about many different situations of lamps lasting from 1000 to 5000 hours. The truth, I only know the general guidelines.

Is the new lamp ok?

4,3 x 2,8m semi-blacked out media room | 2010 MacMini > Pioneer VSX-520-K > JVC RS50 (X7) > 107", 1.1 gain, white screen | JVC X30 (RS45)

Yes, the new lamp is OK as off last night. Its the original ones from Epson. It is $380? Dang! I hope it last me another 8 years like the first one.

I hope in 5 years there is a real native 4K projector from Epson and a little affordable too.

I've had my 8700UB for 9 years and it's worked great. I've swapped the bulb a couple of times and the life of a bulb is a lot better when I switched it to the elevation mode where it gets more active cooling. Recently, I've noticed that it now has a red band on the bottom and then blue/green on the top. I found a Youtube video that talks about taking it apart to press down on a lens. There was one comment where someone was able to access this lens from the bulb opening. I was curious if anyone else had any tips to fix this issue.

Press down here with medium lightly with your thumbs to reseat the lense.

I do not think you can get access through the lamp. The upper PCB, iris, and CF switch bracket will need to be removed to get good access. Otherwise you can just remove the CF microswitch bracket and get some access, but not enough to get your thumb in there. It really isnt to big of a deal. Remove the upper PCB, then 3 screws on rubber pads hold down the iris. It will lift straight up. The whole process will take 30 minutes. This happens because there is no adhesive holding in that lense when you turn the projector upside down it can pop loose

Thanks for the help PhotonEngine! It's a good self-isolation task that I will try.
