I just replaced the lamp on my Epson 1080 projector and now something very weird has happened to my picture.

Basically there is a now a noticeable horizontal split between the upper 50% of the image and the lower 50%.

The upper half of my image seems to be lighter and less vivid, while the lower half seems to be the correct image. Where the lighter and darker halves meet in the middle of the screen it creates a very noticeable line through the middle.

Anyone got any thoughts or ideas?

Thanks for the help!

Aaron,

What was the end result with your issue? I am having the same problem. Put a new lamp in today and I have the same problem that you describe.

Aaron / Mike,

I had the exact same thing happen to me to today.

Any one figure out a fix? (maybe it corrects itself after some hours?)

Note that I purchased the replacement bulb from Epson directly (maybe a mistake?)

I have the same problem. Lamp out at 1560 hours. Replaced with no issue, but now I have the horizontal split screen.

Any help would be appreciated.

Does your old lamp still function at all? If it's not completely dead I'd reinstall it to see if the issue is present.

Thanks TF Ghost - But no, my old lamp is done. I don't believe it's possible that it's the lamp. The split is perfectly centered about the calibration image center line. Looks as though the projector is some sort of "mode".

I agree - I can't see how a lamp could cause the symptoms you're seeing unless there was some sort of film over half of it. There's no setting in the projector that can cause it...the only thing I can think of is a problem with the optical block or main board, but that's just a guess.

EDIT: No setting in the "regular" menu. I haven't played around much in the service menu...

Is the bulb housing screwed down all the way tight? I would try taking it out and reseating it, making sure it's in correctly. That's about all I can think of.

I would also look to see if the light defractor got bumped out of place (the clear bumpy panel that you can see when the bulb is removed.)

I had this problem with my 1080 UB, and was lucky because I still had a month left on the warrenty.

Epson replaced the projector (with a refurb unit).

Same issue for me here. Funny I was reading this post yesterday when I was prepping to swap the bulb. I have tried to reseat the bulb but same results. I guess a call to Epson?

Epson sent me a refurb today after a call on monday morning.
Good turn around.
The issue is fixed after hooking up the replacement.

They sent me a Black projector which looks like my Pro Cinema 1080UB, but the menus are different, I noticed the color options are not the same.

It appears that it is a Home Cinema Menu.

Looks like I'll have to call epson again and have them send another one.

Luckily, I don't have this problem. I have a small grey dust blob that you CANNOT see during movies, so no biggie. I have the international version; the EMP-TW2000....maybe there's some slight differences, ie where they are made, components, etc. GOOD LUCK YOU GUYS!

I came to the forum to start a thread, but found this one and was surprised to read that my problem is the exact same as the one in the OP.

From what I've read, replacement solves the problem (of course) but does anyone have any idea what it really is? Bulb? One of the LCD panels or light defracter panle as mentioned above?

When I replaced my bulb there was some problems getting the dead one out, but there wasn't any violent actions in removing it that might have damaged something - I think.

I sent my PJ to an Epson-recommended service center since it's not under warranty anymore, and they "cleaned the optical engine and performed an internal cleaning." However, when I tested it at home there was still a faint version of that same upper half. It's like 80% fixed, but the remaining 20% really bugs me. Annoyingly there's not a strong blue push in the bottom right corner of the image, which is another issue I'll have to point out to the service tech when I return it this week.

I find it very confusing that the issue still remains, but only in reduced state. I don't really see it on light or colourful images, only mid-dark ones (I notice it most when my PS3 is "blank" switching between applications, for instance). I can't image there would be any kind of "burn in" situation since the unit was only powered on for a minute or two when we I first noticed the problem.

Any help would be VERY appreciated.

EDIT: By the way, my unit is HC 1808, not the UB as listed in the OP.

I only want to see my name in lights...

I just replaced the bulb/lamp (2,350 hours) on my 4-year old Epson Powerlite Home Cinema 1080UB and I see the exact same horizontal line appearing across my screen.

My first thought was the new bulb must be defective but the comments here lead me to think it might be something else. Has anyone identified what exactly is causing the horizontal line? Is the bulb in the clear? I'm well beyond warranty.

I have the exact same problem after replacing lamp. I have a Epson 8350. The screen now has a subtle horizontal line and it seems one half is slightly darker than the other. Anyone found a solution other than replacing the projector? I am currently living in Europe and don't know if Epson's warranty covers it here.

Thanks,

Vasco

Just replaced the lamp in my PowerLite ®Home Cinema 1080 UB.  (Old lamp had approx 3100 hrs on it.)  Have the same issue that has been discribed by majority of the folks here in the forum on this treads. Here is a pic of it with just a blank screen projected. 

 

When there is an image on the screen it looks lighter at the top.  (Keep in mind my projector is ceiling mounted.)  Here is an example:

 

Other than replacement with a refurb has anyone had success at trying a different bulb or some other fix?  I've reset the lamp timer, cycled through the different color modes with the same result.  I have not reset "All" settings yet to see if that does anything.  Will call Epson tomorrow to see what they say. :/

I also have this issue now on an Epson HC 8350 after replacing my original lamp with a cheap ($58) unit I found on Amazon. I'll try to reseat the lamp tomorrow after the unit is cooled down. I can't turn it off for any extended period right now with the world series on.

Interesting...I too replaced my lamp with one from Amazon.  Is this the lamp/vendor?

Ordered a OEM Epson lamp.  I'll update on the outcome once I get it and get it installed in the projector.

I have an Epson 1080 UB and had this same problem when replacing the bulb (with an OEM Epson bulb).  Just run the projector.  After 10-15 hours or use the problem goes away and everything will be fine.

Hey thanks Bradword!  I'll try that and see.  Since I'm out of warranty when I called Epson they referred me to a local approved service center.  (Place that does repair on projectors, printers, etc)  The local center said $90/hour to check out the problem.  So I'll try your method first. :)

I have the exact same problem as described here on my 8350. Replacement lamp from Amazon (first one I recieved blew within 2 minutes, recevived replacement and now have this horizontal line half way through). I have put about 5 hours on the new lamp and have not noticed it going away at all...

Feedback or recommend solutions (other than replacing the projector) would be very much appreachated.

Thanks

Im @ around 25-30 hours the line still exists, it is no where near as bad as it was and can only be seen in certain scenes but it is still there frown.gif
My projector is still under warranty but it has been very good for me so I dont want to risk sending it back and getting a refub replacement.

Keep running it and in high lamp mode. Could just be a oxidized connector pin in the receiving side. I'd put a small amount of deoxit 5 on the lamps pins and plug and unplug it a few times. Don't get messy with that stuff keep it clean. deoxit 5 also is noted for increased electrics / more juice. smile.gif

Anyone figure this one out? Does running it 15+ hours work? I've run it about five hours so far. I'll try to run it as much as possible before my replacement arrives and I have to send this unit back.

I made a post about it in the owner's thread:
