Just an update and a thumbs up to Epson for standing behind their product.

I bought my projector in late 2012, used it for ~100 hours and it has sat in my basement unused until this spring. Picture went dim last week after hitting the 300 hour mark and 6 months after the 2 year warranty (and well past the 90 day bulb warranty from 2012).
Called in to Epson today for second time and they have agreed to send me a free bulb!

Refreshing to have a company back a product well after the warranty.

I will buy and recommend Epson after this experience.

I have been buying my bulbs from ebay. Some company called electrified something or another. Can't remember off the top my head. I always have to search my history to find them.

Anyway the last bulb with the housing cost me about $30. I bought it several months ago and it is still new in the box. My current bulb which I purchased from them for about $39 over a year ago is still running at 1759 hours. They aren't quite as bright as the oem bulbs so I always run in living room mode. Yes 1759 hours on a $40 bulb in living room mode the whole time! I never got that kind of life out of an oem.

I will never pay $250 - $300 again.

Update, my $39 ebay bulb finally blew tonight on my 8500UB. It had 1938 hours on it. I had the replacement $30 bulb on hand (price keep dropping) and it is working fine so far (couple hours). Nothing like a fresh new bulb for a crisp bright image!

Failing fans ???

Hi all,


I love my 8500ub.


I know it's not 3d, 4k, or "state of the art" anymore, but it serves me well and has a flawless HD picture (after calibration) which is all that I ask.


After over 6 years of ownership, I think one or more of my fans are failing. As I understand it, this projector has 4 internal fans.


If I'm going to have it serviced, I think the safe approach would be to have all four fans replaced at once by an authorized service center.


My question boils down to, how much will this cost, and is it worth it? Or would it make more sense to buy a newer model???


Thanks for the input!

If you like the image.. You might just want to dump the current one you have and purchase this one from Epson:

Installed it last night and my projector is whisper quiet again. The fan I pulled out had gone loose on the spindle and was actually resting against the blower housing (which explains the god-awful noises it made as it spun up when you powered the projector on).

If you ever need a replacement fan for your 8500UB, I highly recommend scandig as a seller on eBay. He worked with me to figure out which fan I needed, assured me that these are the original OEM parts and provided a PDF of the exploded view of the 8500UB so I could see where each fan was and pick the right one. Very helpful!
The same thing happened to my power supply fan and im needing to replace it. I have been oiling it with cooking oil every 3 months for 2 years just to keep it going. Last night, I used motor oil.

Planning my upgrade from the 8500ub

Hey all. At long last I am making my plans to upgrade my 8500 to something like the 5040. I am curious how others have handled selling the 8500? Or if you did at all? Craigslists? The classifieds here? What kind of price is considered fair for this machine?

Thanks

Not sure if you are still needing this info, but you can find all the spec for the 8500 here;

I've had my 8500 UB since I moved into the house that came with it in 2011. We use this projector like a TV (since we don't have one), and it gets a good 5 hours per day easy. Been through 2 replacement bulbs that lasted over 2 years each time with no drama other than the picture suddenly dimming, then the projector shutting down to flashing red light mode. But a few days ago, I heard a loud pop and projector shut down to the red flashing light mode. Never had that happen before when the last 2 bulbs died. This one that popped is from the same company as the previous one. Does this sometimes happen, or should I be concerned that something caused it? I was expecting the bulb to go soon, because we're getting past 3500 hours. Should I be worried that the bulb actually shattered? It's suspended from the ceiling, so don't want to open it in place and have it all fall onto the sofa and floor. If I have to dismount it, I can, it's just a pain because it's so high up (10' ceilings).

Avax, what lamp model should we search for on ebay? I see one seller with an "Electrified Lamps" logo with a lightning bolt, with username "electrifieddiscountersinc203". Is that them?

3500 hours is impressive. What brand/company is the bulb from? How many hours was the lamp rated for?
Yes, lamps to go pop on occasion. This lamp is contained within a housing and damage should be contained within. Most likely little, if any, damage will have been caused to the projector. But, I'd hold a container (bucket, baking pan) below the lamp hatch when you open it to catch anything.

Best, Scott

projectorlampsource.ca since I'm in Canada and their office is local to me. There is also a projectorlampsource.com out of Florida that has the same web design, so I assume they are the same. Price was the cheapest I found for what they claim is authentic OEM Philips lamps, and they also had the longest warranty (1 year now).

But a lamp for $22 USD that lasts for 1700 hours is hard to resist. At that price, it's worth it even just as a backup, and even if it only lasts 1000 hours.

I've had a bulb pop in mine, also at about 3,500 hours. So now I replace them at 3,200 regardless (though I'll hang on to the bulb I pull in case I need a temporary spare). Been getting mine from Pureland Supply here in the states for years now, as they use the authentic Osram bulbs (and are usually the cheapest). If it tells you how much use mine gets, I'm on my 6th bulb.

Some things to be aware of: First, I would NOT pull the projector down from the ceiling with the glass still in it. You risk any loose glass going into the duct where the cooling fan blows air into the bulb housing. The LCD engine is all enclosed, so no worries on any damage there. Just have someone hold a bucket under it when you open the bulb cavity and remove the bulb. Odds are good that most of the glass will still be in the bulb housing you're pulling out... but when these things pop, they tend to expel powder-like shards. After you pull the bulb housing out, I recommend taking a vacuum nozzle and cleaning out the cavity, being careful not to brush against the diffuser lens that the bulb shines into. You can also CAREFULLY use canned air to blow it out, but be careful not to blow it in the direction of the duct that blows into the lens cavity. Blow it out toward the front of the projector, in the direction of the exhaust fan/vents.

Something you should look out for: When my bulb popped, it created enough force to shift the first lens after the diffuser out of alignment, causing a red line at the top of the screen. Don't panic! There's a thread here with detailed instructions on how to open your projector up and push that one lens back into place IF that happens to you. It's also a good thread to bookmark if you start getting a noisy fan, because you can get replacement fans on eBay and swap them out yourself once you know how to get to them. I changed out two of my fans.

Thanks Jeremy. I ended up ordering the EBAY bulb that Avax recommended. For $22 it's not much of a risk, and I can always use it as a backup if it's not great. Also, my projector has had the pink/blue bands for a while now, at least since the last bulb replacement. Just never felt like opening it up until this bulb exploded, but figured I gotta do it now to vac out all the glass dust that I can see after removing the lamp assembly.

I posted in the other thread, but I can't seem to get the top of the case off. The sides came off, but the top is stuck on something and I don't want to break any of the plastic tabs that are likely holding it together somewhere. Got any tips?

Can anyone help? I've removed 7 screws in total - 2 along each side, and 3 across the front. Did I miss any?

Nevermind, I found the other ones. One was hiding under the ceiling mount.

All back together now, blue and pink bands gone! Also, new $22 EBAY bulb installed. Picture looks great, but will check again during daylight to see if there are any brightness issues.
