The Offical Epson 8350 Owners Thread - Page 258

post #7711 of 8634
Hello!


I originally bought an Epson 8345, but returned it after I got several auto-iris errors. Kudos to Epson, however, for their excellent customer service - they were going to overnight me a replacement but I was still under my store return period. I loved the picture but at 12' away on a 106" budget screen, I found the black level lackluster in a light-controlled room with dark walls, even with adjustments.

I ended up picking up an 8350 instead and have to say the little bump in specs makes a huge difference in the blacks. I had them both running for an evening, and found that i had to place the 8345 about 7 feet further away to get close to the 8350 black levels at 12',


now... my "problem"...


I noticed there is a gradual darkening from left to right of my screen image on a full black screen. ie: the left side is slightly brighter than the right. You don't really notice on full 16:9, but when watching letterbox it's very noticeable to me with the black bars. Has anyone else experienced this? I also noticed a small darker "blotch" in the lower left quadrant of the screen, that remains if I zoom the lens in or out, leading me to believe it's something on/in the lens or the internal LCD. It's not very noticeable, but I know it's there. Should I be concerned?

I swear im about to throw this damn thing through the wall. So I get my second unit and good news, this one doesn't destroy my entire home theater. However when I project an image on the screen it's crooked. Im pretty sure my shelf is level so I play with the little feet on the bottom and make it level. Now the the image.......pulls one way. It's hard to describe but one side is pushed in at the top and the and the other hangs. Whats causing this? I call Epson but of course they are worthless. I have tried turning this piece of crap every which way but nothing helps. Im seriously thinking about sending it back and forgetting projectors altogether.

As previously stated directly above, the the projector is not squared or plum to the screen.. You should check your shelf with a bubble level to see if it is level both side to side and front to back. From your description that it appears that it is tilted slightly upward

Problems such as yours are almost always installation related. Try not to let frustrate shin get the better of you.. It can be quite a job repairing a projector sized hole in drywall, and somehow I don't think up something would allow a return if the projector shows such obvious Consumer misuse.

If you can and are willing post a video of what the problem is. Give us a walk around the screen and where the projector is.

I can't I don't own a video camera sad to say. However the above suggestions will help I think. Im going to try moving it around later. Problem is I will have to move the shelf and it needs to screw into a stud. Also the way my room is shaped might make this difficult but im trying. It took me forever to get this projector and I keep running into one awful frustration after another. Im still waiting on a receiver to be fixed that the first projector ruined.

However then what is lens shift for? I was told it could be slightly or high up because that would take care of it.

Dang no camera, even on your phone?

Anyways when the projector is level you can use lens shift to move the screen horizontal and vertical a significant amount. keep on mind that the each adjustment effects the other.

So it looks like the best place to place the projector is above the thermostat.......iwhat are the odds im going to put a screw through a wire and end up burning my house down?

Non-existant. Thermostat wiring is universally "low voltage". You can no more start a fire that way than you can pinning a Stereo wire.

You might freeze to death though.....

Why move the Shelf? Simply install needed "shims" under the PJ's feet to correct any tilt or yaw. If you don't know what a shim is...or do not possess a Level, call in a Pro and end all the guesswork & frustration.

I sure hope you're not confusing lens shift with keystone adjustments. I've owned several projectors in the past and this was by far the easiest to set up.

I'm not sure that you need to remount your shelf. It sounds like you could have the left or right side of the projector slightly twisted out of position. Between tweaking that and adjusting the foot levelers you may be able to get it square without needing to move your shelf. Keep in mind that the problem may not be with the wall that your shelf is mounted to, but rather the wall that your screen is mounted on. Either way, twisting the projector slightly (i.e., bringing the one side of the projector closer to the screen by a few millimeters) and playing with the feet levelers may fix it, depending on how far off things are.

It means the front surface of the lens is not parallel to the screen.

 

After you make it parallel (by repositioning projector) , use the lens shift thumb wheels on top to move the image back over. If you cannot move it far enough, you will have to move the projector over some more ... slide exactly left or right (keeping lens parallel to screen).

i recently bought a 8350 and for the most part im very happy with it. the only problem that im finding is when im watching a movie with really dark scenes that may have a portion of bright light in it i get a foggy/blotchy looking image around the lighted area. i am not sure if this is just a settings problem or just that the projector is too low end to have better shadows. i have also checked and cleaned the lens and filters, so any ideas would be great!

thanks, keith

What is the source material and input device?

 

If source material is low quality (for a screen size this large) you might be seeing poor color dithering aka "banding" ?

I tried twisting it and playing with the feet. Nothing worked until I moved it.

So, is it banding?

If not, a pic might help or an example movie and time or scene might help.

Ya, the Lens Shift is amazing (and you don't have to have the lens in the horizontal center of the screen) but there are limits to what it can do.

 

Good to hear you got it figured out.

 

However, if I was to permanently mount mine from the ceiling, I would have a hard time NOT putting the pole in the middle of the screen (guess that's why mine is still on the shelf). smile.gif

yes from that link you sent that is def what it seems to be, the first image is what i see in most really dark scenes in movies such as batman the dark knight rises. i notice it when there is reflections off of walls or when looking at image of the sky at night where a spot light or moon may be showing

In 8350, check your Color Mode and HDMI Video Range (see manual).

 

In PS3, check for anything that might affect color output ... bits level, deep color, etc. Be sure it's set to 1080p.

 

If running it through an AVR, be sure it's isn't doing anything weird to signal (just set to pass-thru).

 

Just watched Dark Knight Rises the other night. Don't remember seeing any banding.

Well semi figured out. It's sitting on a table that is really taking up space that I need. Putting that shelf up is becoming troublesome. And of course ceiling mounting is out because of the tiles. I had the lay out of my house.
post #7736 of 8634
If anything, ceiling tiles make the installation easier, at least in regards to exact placement and hiding wires. Remove the tiles above where you want the projector, screw in a board to the studs, screw the projector mount to the board, and make sure the its a mount with a pole that falls under the ceiling level. Mark that spot, cut a hole in the tile for the pole to pass through, then mount the projector.

if that all seems a bit over your skill level, you really should hire a pro... At least then you can start enjoying your investment instead of stressing over it. With the lens shift, a pro can easily have the job done in an hour, so labor isn't really going to break the bank.
post #7737 of 8634
So I just got another receiver after the last one was destroyed. its a Yamaha RX-V673BL. I connect a 50 foot cable from the receiver to the projector. I used the same cable yesterday on the very same blu-ray player and it worked fine. Now the projector just says not supported. WHAT NOW? The guy at Yamaha said that the cable could be too long but I know it works. He said the longest cable I should use is 15 feet. Really? My projector is more than 15 feet away and im certainly not going to run a cable across the floor, no im running it along the wall. I think im just going to get rid of the projector, im obviously too stupid to get it right, story of my life.

Just a quick note.

The side panels come off very easily:

Remove screws with unit upside down.

(you can turn the back rightside up to make this next step easier...)

Pull/rotate bottom edge only of the side panel outward. Once the bottom edge just clears the chassis, lift straight up to disengage top clips and pull away from unit. To replace, hook top edge over clips and rotate bottom in to seat.

Sounds way harder than it is!

Here is my long run. Notice I use cables with known heavy gauge wires inside. Pretty sure that is the key to using long cables. Better to "over build" your run than it be "not enough".

 

Final 57ft HDMI chain to Epson 8350:
Onkyo TX-sr607 7.2 HDMI AVR
2ft 24AWG CL2 High Speed HDMI Cable w/ Net
4X2 True Matrix HDMI 1.3a Powered Switch w/ Remote (Rev. 3.0) (MonoPrice # 5312)
45ft 22AWG CL2 Standard Speed w/ Ethernet HDMI Cable
HDMI Active Equalizer Extender Repeater (MonoPrice # 2849)
12ft 24AWG CL2 High Speed HDMI Cable w/ Net
Epson Home Cinema 8350 Projector
18 ft. from wall/screen = (96" or 8ft diag. image)

 

The HDMI switch is really just being used as a splitter (clone signal) for the plasma. MonoPrice has a smaller/cheaper HDMI 1.3 splitter-only box but since this one works, I never got around to trying it. Not sure if HDMI switch is doing anything to stabilize signal or not (before it heads-out on long run). I have a feeling it doesn't (but doesn't diminish signal either).

 

My projector is in the back of the room on the counter. Since you have to go up-and-down-walls ... this chews-up some cable length. If I ever ceiling mount mine, I'll just pull the 45 ft cable back into ceiling and it will easily reach the ceiling mount (with some to spare). The final 12ft. extension won't be needed any more. The HDMI Active Equalizer is passive (non-powered) and really just a fancy female-to-female adapter (with a little extra insurance). Pretty sure I tried it with a plain adapter and it worked also. The 45ft cable is over 0.50 inches in diameter. Needless to say, it doesn't bend well.

Try the Blu-Ray player again, directly to the projector (no amp).

 

What is the make and model of this cable? What is the gauge?
