That's good. Just hope the next one is working good. Good luck.
post #2672 of 2876
Hello All,

Been looking on the avs forum for something like my current issue, not sure if its similar.

My 8700s been working great. I recently reset it to factory to tinker with some settings. And after watching a few movies I notice a dull white "softball" size spot on my screen. Its not on the screen itself, because I can shift the lens up and down and the balls moves up and down with it. It's not visible during movies itself, only if the movie cuts to black. Its on the bottom center on the screen.

When booting up my sony Blu ray player, I don't see the blob anywhere on the screen on the menus or anything.

I gently wiped the front of the lens off as epson instructs, but its still there. Is this something to be worried about? I've only got about 30 hours on the original bulb, the projector itself is under a year old I believe.

Its hard to take a picture of it due to lighting and such, or I would have posted.

Any help would be appreciated. Thanks!!

For you 8700 owners, I'm looking at a refurb unit for a home theater in my basement. I'm planning on a 120" screen with a gain of about 1.2. Ambient light is not a problem as the room has no windows. My outlet and hdmi cable are mounted in the ceiling about 17' from the screen. I've been playing around with some calculators and am totally confused as to whether the 8700ub would work well with my room configuration. Can anyone help me out?
post #2674 of 2876
Update on my 8700. I received the replacement from Epson the other day. The color variation between the two sides is now minimal. I calibrated it using the AVSHD disc using the theater black1 setting and the picture looks great. So far I've been pleased with Epson projectors.

Having had an 8700 for almost two years in a fully light controlled room on the same size and gain screen with a throw distance of 16 feet I think you will be frustrated at 17 and will not be able to use eco mode. If you can't step up to a 5010 then I would say it would be worth the probably few hours hassle of moving your cables closer up like 13 or 14 feet....you will be much happier with the brightness and quieter eco mode.

Is it there when you pull up the pattern screen? Also have you called Epson to see if they have any other suggestions?
post #2679 of 2876
I did speak to epson, they gave me some things to try.

I unplugged all hdmi cables(I tested 3 diff cables, 2 diff blu ray players).

Shut of the machine an restarted it. There is no softball at this stage.

I plug in sony blu ray and start with no blu ray in. There is no softball at this stage.

I put in a blu ray and start playing, it then appears but only during cut or black scenes, with any blu ray or dvd i play. During a widescreen movie, there is no softball. But say that movie cuts to another scene, or a black screne frame. It then shows up, and does it every time.

I have cleaned the lens off again with a lint free cloth, still happeneing.

It's not a MAJOR issue, just kind of a "wtf is that"? I'm waiting on epsons second reply.

They assured me its probably not the board. But I am still waiting to hear. I would take a picture, but it's virtually impossible with my camera to make it show up.

Should I try to replace the bulb? Or even attempt any type of internal cleaning?

ANy help would be great! Thanks!biggrin.gif


BTW: Rise of the Planet of the Apes looked amazing on Blu-ray with default 8700 settings!! wink.gif

I heard back from Epson...

"The issue you may experiencing may not be an issue with just the lens. You may be having trouble with the optical engine of your projector"

They are able to replace the whole unit or offered up 3 places locally to service it under warranty.

Which do you think is a better option, replacing and probably getting a refurb? I've read some people having bad experiences getting refurb units.

Or bringing it to a service center and have them work on the one I have?

I would like to know your thoughts! confused.gif

I had a green dust blob in the top right-hand corner of my screen on my first 8700UB-R from Vapex. I tried to secure a new unit through Epson last week, but their inventory had, at the time, apparently dwindled to zero. I would be inclined to try the service center route. The unit might get a good look over and cleanup to a degree that perhaps Epson has been unable to provide with their volume of turnaround units. You will still be under warranty after the service center visit too. Anyway it seems that the message from previous posters on this forum is just to be persistent and that you will get a unit with a clean bill of health eventually. I, for one, don't mind waiting - I just want to get one that's right. I'm sure that's the same for you?
post #2682 of 2876
I also got a green dust blob and I got it from Vapex about 3 weeks ago. I'm going to wait awhile and see what happens.

Correct, I dont mind waiting for one thats right. I just don't want to ship back and forth if I get a bum refurb unit. I'm leaning taking it to the service center, which is about 20 mins away from me and letting them take a look. All else fails I can just go the epson refurn route I guess eh?
post #2684 of 2876
Had a problem with my 8700 it just power off by it's self. I waited about 5 minutes and turned it back on and no more problems This was the second time in two weeks that has happen. Have others had this problem before thanks. mad.gif

Is it possibly overheating?
post #2686 of 2876
It's on a shelf with a lot of open space around it and I had no warning lights on the projector.

Have you tried a different outlet and cord?

I would contact Epson support and see if they an offer assistance, espcially if it is under warranty.
post #2688 of 2876
Spoke to Epson support and I have to send it in for service. I'm taking my 8700 to a local service center that Epson give me.

Yes, I think you can. Plus it seems that the more problems and/or RMAs a particular customer has to deal with, the more Epson prioritizes that customer. There was one guy on this forum who I think ended up getting shipped a 5010 after successive returns of an 8700-R and another who actually received a brand new 8700. I would suggest just keeping a paper trail of all transactions and notes of customer service communications so you can present a complete history if the manufacturer requests it.
post #2690 of 2876
Great, thanks!

I have started a request with projector doctors in GA that epson referred me to. I'll post when I get it repaired, hopefully all is well!
post #2691 of 2876
Good morning,

After contemplating to buy the 8350 for the past 2 months, i somehow stumbled upon what i thought was a good deal on a brand new epson 8700ub. I paid $999.99 for a brand new unit yesterday when the 8350 is currently selling for 1149.00 on amazon. So far, i have been playing with this projector for about 3 hours and i like it. however, i dont have a screen yet (but will order it in the next few days). I have the projector in my living room, white walls all around which includes a white ceiling and a big window with vertical blinds so it does get some external light during the day. Here are a few of my concerns:



1. Should i get a grey screen or a white screen?? i have done lots of reading and grey seems to be best when walls are white and you have possible ambient light from the outside. I am going to project around 100 inches..

2. WHY do i feel as if the image is not very sharp? i have done the blue pattern and adjusted it over and over again, but even on blurays it looks somewhat "out of focus" like it doesnt have pretty spot on sharpness. Is it because i am using the wall right now? will it look sharper once i project the image on an actual screen?

3. I have read about a zillion reviews and most rave about the thx mode. I have personally used it and it looks somewhat "dull" or does not pop. Actually, i like the "theater 2" mode better. Does anyone feel the same way here?

4. I have tried looking for calibration settings from others to see if i can improve upon factory settings, but i have not found any. Can anyone link me to some good settiings?

thanks in advance for your help. Happy holidays to all of you.

My suggestion is to ask all these questions again once you have a screen. Also, if you want more "pop", don't get a grey screen. I'm still using my old Viewtec Silverstar 110" with my 8700UB. And it "POPS" in eco mode. Running in Theater 1 nicely calibrated. I didn't like THX either. BTW, the Silverstar is a +3 gain screen. I can watch TV with the drapes open in regular mode. Oh yeah, since I use a HTPC to drive it, I just let IT do a full color calibration using an iOne USB puck. Makes a damn fine PC desktop at 110" as well!
I don't use other sources, so for me a computer based calibration works well.

So your true results will depend on your screen choice before you start tweaking things. wink.gif It may also be sharper on a true flat surface, although some 8700's are not as sharp as others. Pin a sheet of paper to the wall and see if the pixels are visible. If they are, then that's it. There are limits to the optics in a product based on this price point. Also, if it is TOO sharp, you'll notice the pixel structure instead of enjoying a movie. Film isn't razor sharp either. My suggestion, focus it using a windows desk top. I got the best settings looking at black text on a white background and then left it alone.

That is a very good deal indeed. And as I'm sure that Tinman will attest to, the 8700UB has a wealth of brightness available with it's 1600 lumen output due to it's lens configuration and it's exceptional Dynamic Contrast specs. And at / on a 100" screen, from a average of 14' throw, you's get 24 foot lambert of reflected brightness on a 0.8 gain Gray surface. Bump up the gain to 1.2 and you achieve 36 fls...a truly "usable" level of reflected brightness.

All respect due Tinman, his referencing a SilverStar as an example isn't really relevant since even with adjustment to a more acceptable gain specification (2.5) than the ambiguous 3.0+ gain the Mfg originally stated, you'd be up in a stratospheric level of brightness...76 fls That's not "PoP"...that's more akin to having a unmitigated Solar Flare headed your direction. Hence, if a 8700 is calibrated to D65 and run on Low Lamp mode, any Screen with /or an excess of 1.2 gain will be sufficient for your needs.

Your in a pretty "Gray" area now (...a Pun, but an appropriate one...) because unless you do one or more of the following, your room will work decidedly against your maintaining optimal Image Quality.

  • Substantially reduce your Room's reflection index. The singular worst case is the Ceiling, unless the side walls are really crowding the outside edges of the screen. If you cannot consider changing your room's color scheme.....
  • ....You have to concentrate on using a +1.0 gain Gray surface, one that is just as retro-reflective as the SilverStar, so as to minimize / eliminate light scatter from reaching the ceiling / walls.
  • ....but that also means limiting yourself to the kind if projector positioning such screens require.

The type "Mfg" screens you need to consider that would effectively erase your ambient light concerns cost upwards of +3x what you managed to latch onto the 8700Ub for. Or more.....a LOT more. Owwww.

The Black Diamond / Silver Star / DNP Supernovas are the ones to reference . Check the AVS Classifieds, or the corresponding Screen Threads for each....because many people sell their old Screens quite often.

As for any other more 'sanity-based price' options, your saving grace is the smaller screen size you have....and if you can crowd the screen with a shortest possible Throw Distance (10'.2") and achieve a whoppin' 61 fls with a 1.2 gain Gray, you can then offset your room's reflections...leastwise as much as possible without having to repaint or cover the offending surfaces.

You can source a few Mfg Fixed Screens w/High Contrast Gray material that will price out at a more reasonable $800.00-$1000.00

........................or consider one of the high performance DIY Painted Screen options over on http://www.avsforum.com/f/110/diy-screen-section Why, at 100' diagonal, The Silver Spandex Screen application is also a consideration, and even the most expensive DIY option will price in at under $250.00 total. There are 1.3 / 1.4 gain Gray or Silver DIY Screens to consider.

Much has to do with surface smoothness, as well as pixel density. At 100" diagonal and with a 8700UB shooting from a minimum distance, clarity should NOT be an issue at all. You might want to consider match up your 8700UP with a Darbee Doublet processor. I've used them on PJs ranging from 1280 x 800 presentation PJs to top end JVCs and all of them can obtain a degree of improvement.

However........... if the 8700s convergence is way off, or you actually do have a optics issue, no processor or calibration will turn the proverbial Sow's Ear into a Silk Purse. I do tend to take slight issue with the comment that the 8700's optics could be inherently at fault out of hand (...price point wise...) , because when "New"...it most certainly was NOT a "el Cheapo" Projector, nor one considered to be a compromise performance or hardware wise. In fact, it has to be said that at the price you pad for it, your PJ has absolutely far better optics than it possibly could otherwise be expected to have

Viewing Mode selection is completely subjective. One Man's joy is another Man's sorrow. What is certain is that THX Mode in fact has more naysayers than advocates one the End User really starts exploring calibration options. THX Mode is a "Out of the Box" preset Mode that is intended to get you closer to what the Director / Editor intended you to see. That is not to say you'll be happy with it, and in your case, the greatly lessened Lumen output won't do much to help you combat the effects of ambient light wash-out. Any "projected Black" that hits the screen with more intensity than ambient or reflected light does will tend to maintain a higher degree of image quality than a image that has less to work with. while this may seem patently obvious, for many it's something that totally escapes their reasoning. ..............and, if the Screen surface also works to enhance black levels, and is supplied with adequate lumens, those same blacks will maintain their quality all the more readily and easily.

thanks in advance for your help. Happy holidays to all of you.

Forget about using other's settings. about the only time that can work at all is if you have a wholly optimal room set-up (...and you do not...) the PJ is placed exactly the same....and the Screen surface employed is identical. And even then, the variables between Lamp performance, calibration software, and personal preference makes successfully using such pre-tried settings a case of problematical success at very best. Reviewer's settings usually are simply to compensate for adverse Factory settings...that's about it.

Here's hoping you and yours all have a Happy, Blessed, and safe Holiday season. And hopefully you'll ring in the New year with a good understanding and directed purpose as to how to maximize yout great PJ investment.

Just received my 8700ub-r and wanted to make sure i wasn't crazy. When i put the projector into eco mode I get a loud buzzing that sounds like the fan but it's much too loud. There is no noise in normal lamp mode. I've had an 8500ub before and it didn't make this noise. This is abnormal correct?

Aggravating as the picture and convergence look good. I'll call Epson later tonight or tomorrow but wanted to make sure this wasn't a known issue.
post #2695 of 2876
i just tried doing the eco mode and i dont get the crazy noise you are talking about..i do hear more noise inside, but i dont hear the sound you are describing..
post #2696 of 2876
well, I left it on normal for 15-20 minutes then changed it back to eco and the noise is gone. I can now switch back and forth without reproducing it. I'll have to see if it reappears tomorrow after letting it sit turned off all night.

edit: well, powered up this morning and no noise. Switched to normal and back to eco and still no noise. Maybe it was just something shaken up a bit during shipping that's sorted itself out. As long as it doesn't reproduce itself I've got a keeper.

edit, again: gah, spoke too soon. Just started with the obnoxious sound again. Looks like I'll have to go through the replacement process with Epson.

post #2697 of 2876
really weird..my unit is flawless "knock on wood" and so far my only dliemna is figuring out what screen to buy for the projector.. i am inclined to purchase a grey unit, but i had someone tell me to purchase a matte white? all my walls and ceiling are white..
post #2698 of 2876
yeah, replacement is on the way. The picture was excellent, I think the convergence was off less than a pixel but I'm not the best judge of that unless it's way off. No uniformity issues. Without the obnoxious sound I could even hear over my 5.1 setup I would have been really happy with it.

I had to do a warranty claim with my 8500ub, as well, and Epson's customer service has been painless both times. Hopefully the replacement's a good one and I'll be done with it...or maybe if I keep having to be on the replacement carousel I'll get lucky like the few in this thread and end up with a 5010.

afraid I can't help much with the screen choice. I'm in a cave with dark blue walls and full light control and mine looked fantastic with my matte white screen at 120".
