The number one complaint is brightness, number two is longevity.

I should add for your information, from elsewhere on the internet:

Who Makes Projector Lamps?

High quality projector lamps that meet industry standards are only made by a few projector lamp manufacturers in the world. Manufacturing projector lamps is an incredibly expensive and challenging technological process that only a few companies are able to meet.

The major manufacturers in the projector lamp industry are -

Philips - The pioneer of the projector lamp world. In 1995 they began researching and developing the first metal halide lamps. They eventually developed a mercury vapor projector lamp, which they called a UHP lamp or ultra-high pressure mercury vapor. The new development made it possible for projection systems to emit a brightness never before seen, and made digital projectors possible. Philips remains a dominant force in the projector lamp industry, and some estimates indicate Philips has more than 70% control over the projector lamp manufacturing and sales market today worldwide.

Ushio - Founded in Japan, but now with offices around the world, Ushio manufactures hundreds of different industrial lights, lamps and bulbs. The company started in1964 as an industrial light manufacturer. Ushio manufactures projector lamps for Sony, Sanyo, BenQ, and many other companies. Estimates indicate they have a 10% share in the projector lamp market.

Osram - Osram started in Germany. The company specializes in producing the ARC tube in mercury vapor lamps and metal halide lamps. Osram claims to be the second largest lighting manufacturer in the world, with about a 7% market share.

The Others - There’s a handful of projector lamp manufacturers in Taiwan, Japan, and China. The most notable is Matsushita, which is a subsidiary of Epson and manufacturers all of Epson's lamps. Most smaller manufacturers of projector lamps don’t produce high quality lamps and aren’t commonly found in new projectors.

Where have people been getting replacement lamps lately with good results? I ordered one of the off brands of amazon a while back and it's been flickering quite a bit lately so I know it's close to the end now...

Edit, went and looked and I ordered this one last June 11th http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1

If you are talking about an OEM lamp, then Provantage. A company I (and others) have dealt with and highly recommend.

first replacement coming

So after a year and a half of projection bliss, my 8350 bit the dust the other night, unexpectedly. The day before it made a rapid "clicking" noise during startup, twice, and then yesterday I attempted to record the sound on my phone but I instead was greeted by a halting "grind", two blinking lights, and a very loud fan noise. I believe it's the auto-iris. Its funny because I don't remember having it on, but oh well.

Epson was very prompt on the phone, I swear it was a five minute call and I have a refurbished replacement heading my way. I have my fingers crossed that this one will be as near perfect as my first - I had a slight convergence issue but other than that, it was perfect.

I was wondering, and it's probably been asked - would they make a fuss if I pop out the old lamp and keep it as a spare before sending back the defunct unit? As I'm sure its an auto iris problem, I'm sure the old lamp should still be fine.

Also, now I've only got 6 months left in the the 2 year warranty - should anything like this happen again afterwards, has anyone had success getting extended support via their credit card coverage?

OEM bulb on my 8350 died today after only about 10 months and 1050 hours (it's used as my main TV). The original bulb that came with it lasted around 2400 hours and over 2 years. Really feel let down by this, seems more like the performance I should expect out of a cheap knock off not an expensive OEM.

Has anyone been able to successfully get Epson to replace a lamp like this outside of the 90 day warranty period? I'm curious if it's worth my time to call support and plead my case on the short life span, or if they're just going to tell me to go pound sand.

I've also been thinking about getting a replacement projector anyway, a refurb 5020 from VA. Do those bulbs tend to be a little more robust? Browsing through this thread, people seem to have a lot of Epson bulbs blowing early. Most everyone seemed to have good luck getting them replaced, however those projectors were still under warranty themselves. My 8350 is about 4 years old now.

bulbs are always a crapshoot. they can last 2000 hours, 1000 hours or 5,000 hours and that's off of the same "batch"

This is precisely why I'm considering the "after market" bulbs at one quarter the price! There are only so many places that actually make the lamp although I'll admit I haven't research that recently. I do know I've replaced more of my "10 year" CFLs in the past 3 years than I EVER remember replacing my incandescent bulbs (yes I know this has nothing directly to do with the conversation!!!!!!)

In my experience the auto-iris makes a sort of low level rattling sound when it is working. I sit only about 3 feet below the projector, and with a movie running I hardly notice it.

I've seen the light... and its "White 255"!! (or is it 235?)

Hello, I searched around and couldn't find anything. Does the Epson 8350 have a service manual? I want to fix my projector but didn't want to proceed until I read up a little. Thanks!

Deep color mode ps4

Been having a strange issue while using my ps4 with the epson 8350.
At first I thought it was my ps4 so I sent it in to be warrantied, got a new one back and it's doing the same thing so I'm afraid it's the projector.

Has anyone else had an issue where the screen goes black for a second and comes back with multicolored snow? It's the strangest effect, looks just like old tv no signal snow but with color in the mix, sometimes it will appear as a small box multicolored square, It only does this with the ps4 While my ps4 was shipped off I had my computer connected for two weeks straight and never had the issue reoccur.

I may have it tracked down to a deep color option in the ps4, so far with it off I have not had a problem but haven't had a chance to test it extensively.

Any opinions on what might be going on?


EDIT: just wanted to add that the issue is intermittent for about 5-15 seconds then picture comes back fine.

It's most likely your HDMI cable. With Deep Color turned off you have decreased the amount of data that has to be transmitted. Nothing really uses Deep Color at this time so having it off is not harming anything. Another test is to turn Deep Color back on but decrease resolution from 1080p to 720p. If it works this way (with less data being transmitted) it's again telling you that the HDMI is operating right at the edge. Replace the cable if it becomes an issue again.

I get the same issue, but only when playing BF4 and only when I have to be a class (assault, engineer, etc). It sucks because you can't change your class, spawn on a teammate, etc.

I'll try changing out the HDMI cable that goes to my projector, as well as switching the deep color OFF to see if it helps.

I managed to get rid of all the dust with this method, so thought I would post this up for others if they want to try it also. It was actually really easy, and I'm happy to have avoided the hassle of having to go the replaced/exchanged route with Epson. All you need is a can of compressed air, a phillips head screwdriver and 20 or so minutes. Obviously, do this at your own risk, I'm not responsible if your projector blows up etc...
I just had the exact same issue and this fixed it. Thanks for taking the time to post this solution!

My EPSON 8350 is connected to a HTPC via HDMI and VIDEO is connected to my audio receiver so that I can see the on-screen display and ensure the DD and DTS Bitstreams are coming through the way I hope (my equipment resides in a separate room from the Home Theater).


My problem is that when my wife starts up the home theater the Epson 8350 sees the VIDEO signal first and automatically displays the on-screen display for the audio receiver and it confuses her. I want it to default to HDMI always. Does anyone know if there is a way of doing this?
