My DaLite "Tensioned Contour Electrol 133" Cinema Vision" has developed a problem. It was purchased and installed in January of 2012, so not quite 2 years old.

I've begun to notice that the screen has developed a series of horizontal bands from edge to edge. These are almost certainly caused from being rolled up for long periods of time, as the distance between these horizontal bands seems to be perfectly regular. I tried leaving the screen in the down position for 2 straight days, but it didn't help. Anything longer than that is dangerous with my kids running around. :-)

While watching a movie/TV, it is only apparent during light colored scenes...but every time one of those occurs, I'm immediately pulled out of whatever I'm watching and start noticing the horizontal lines again...

Has anyone ever experienced such a thing? Is there a remedy? I plan on contacting my dealer about this today, but I wanted to see if I was dealing with a common problem or not.

Thanks!
-Kevin

I'm not sure how well these will convey the problem. I could add some annotations if it would help. (I'm not talking about the bottom corners...looks like my tab tensioning needs some attention)

Front view


Side view


Can anyone see what I'm talking about?

Actually, after the forum re-sizes these, it's just about impossble to see. I've uploaded the images here: http://imgur.com/a/TQrnY

If you go to the imgur site, and click the gear in the upper right corner of each image to view them full size, the problem is a bit easier to see...It's just very difficult to catch with a camera...

Thanks.

Yes, I have this problem also and there's at least one thread somewhere here on this forum about several people experiencing it. I believe the general consensus was that it is coming from a breakdown of the screen backing material or some adhesive in the roller. I have a 10 year old DaLite tensioned Cosmo Electrol 106 HCCV that looks terrible now. From what I remember Da-Lite wasn't super helpful as far as offering to replace anything. I know I'm way too far out of warranty for them to care. But you may have an argument since yours is fairly new.

I'm just going to replace mine with a better Stewart screen.

Kevin,
Here's the thread I mentioned with people having sticky screens with marks like mine. http://www.avsforum.com/t/707439/cleaning-a-da-lite

I also found another thread that looked like some folks were maybe having a slightly different issue with banding/ladder marks possibly from having an acoustically transparent drop added to their screen.

jacksonian,

Thank you for pointing that thread out to me. I've read it in it's entirety. It's interesting. I'm *not* having that problem at all. There is no sticky residue that is causing these horizontal lines. They are not caused by something foreign on the screen, they are caused by "dents" from being stored on the roller (more on that in a bit). However, that thread DID make me realize something else about my screen. All of the tab tension positions on both sides of my screen are oozing glue. In between two of the tension positions I can see a PERFECT outline of another tensioner which lefts its gluey impression when the screen was rolled up... YUCK! Fortunately, this stuff hasn't migrated onto the screen yet.

Back to the creases, or dents.

I did hear back from my dealer (they left a message, and I've yet to speak to them). They had contacted DaLite about my issue and this is what they had to say.

"Try applying heat to the effected area. It's safest to apply the head to the back of the screen, but it can be applied to the front as well. You should also consider leaving your screen in the down position more often."

This is pretty much unacceptable for a > $2000 screen that is only two years old...but anyway. I spent about a hour with my wife's blow-dryer. It works, but it is VERY tedious, and very hard to know when you've done it "enough"...Also, I have no clue how much heat I can apply before I destroy the screen...Very nerve wracking. I've also left the screen down for 3 days now. The results are in. To the naked eye, the ripples are gone...However, The lines ARE NOT GONE when watching a film. It's like this area of the screen now has a different (lower) reflectivity.

I'll be contacting the dealer again. It seems they want me to contact DaLite for any follow up, so I might end up doing that.

-Kevin

Well, after living with the defective screen for far too long, I finally reached out to DaLite, and my vendor.

Over time, the tab tensioners (little plastic guides that glue onto the sides of the screen) started to come loose. This may be because I had left the screen in the down position for almost a year (since I was trying to get rid of the horizontal lines, and knew that rolling it up was part of the problem.) DaLite was happy to send replacement tab tensioners (for free), but I had to escalate to discuss what I could do about my out of warranty screen material.

In the meantime, the tab tensioners came in. I applied one like I was told (simply remove the old one, and put the new one in the exact same location. In a matter of a week, it was clear that the new tensioner was also starting to come loose. Again, this may be because I left the screen down, but they really should have a better way of affixing these things.

Eventually, DaLite via my vendor, offered a replacement at a cost that I was comfortable with. Still extremely expensive in the relative scheme of things, but better than nothing. At some point, my vendor expressed that the new HD progressive might be a better material for me than the Cinema Vision. It was also available in 1.3 gain, so I asked that samples be sent. I ended up liking the HD progressive 1.3. It is a more expensive screen material, but they offered the replacement screen at the same price that I had already been quoted for the replacement Cinema Vision. I went ahead with that order.

During this time, I also considered replacing the entire screen. Mostly because it now comes with a 5 year warranty instead of a 1 year warranty. They also now advertise "Smooth Roll Technology" which seems to indicate that the roller won't cause horizontal lines anymore. And, lastly, the new motor is supposedly quieter. Ultimately, I was told that my replacement screen material (and roller) would come with a 5 year warranty (and it would be this newer roller as well), so the only thing missing from an entire new assembly would be the quieter motor. But mine is quiet enough, and only used before and after viewing, so I didn't care.

Anyway, I hung the new screen two days ago, and have watched 4 movies on it since then. I could detect nothing "new" about the roller. It looks to be exactly the same rolled steel that the old one was. But, the screen looks amazing. I'm very happy. It's hard to remember what the Cinema Vision looked like when new, and I've been dealing with that screen's problems for a very long time, so some of my impression is definitely related to that...But in the end, DaLite, and my vendor did a pretty good job of keeping me happy. We'll see if I need that 5 year warranty or not...

Here are some pics that I sent to DaLite to document the problems with the original screen.

Nice hear that Da Lite stepped up with special pricing. It's been a long time since I owned a Cinema Vision screen myself, but the HD Pro. material is better for sure. Glad it all worked out !!

Can you say, specifically, what you think is better about the HD Pro, compared to the Cinema Vision? When they sent me the samples, I taped each of the 3 1 ft. square samples to the Cinema Vision ( they sent 0.8, 1.0, and 1.3 samples ) and put on a movie. From my seating distance (12 ft, give or take), the 1.3 sample effective disappeared. I had to try very hard to find it, even knowing where it was.

The Cinema Vision material has too many sparkles, and has more screen texture. The HD Pro. is smoother, much finer grained texture. if a screen disappears from your seating distance, that's good - go with it !

Okay, I guess I didn't notice any of those issues with my Cinema Vision from my seating distance. The HD Pro disappeared *against* the Cinema Vision...so, essentially absolutely zero difference between the two "fabrics" from my seating position. I guess that's a good thing, since I had always been happy with it, aside from the fact that it basically fell apart, and developed horizontal lines in less than a couple of years. :-(

What is your seating distance from your 133" screen out of curiosity ?

I think it's 12 ft. But it may be as much as 15 ft. It's been a long time since I measured.
