I am facing the same problem for last 2 days. My observations are:
1- I think it is a software problem.
2- I looks like it is happenning when I use the High Performance graphics adapter. With the on-board adapter I didn't see it..
3- It is only happenning when there are no maximized windows, i.e. it happens if the desktop is on.
4- I believe that most probably it is caused by a windows update.
So Lenovo should offer us something. Hope to hear from them,

I really do think at least mine is a software problem and my issues are more similar to osmank. I really only have the problem running certain programs and I can make it go away by running different programs. I have fewer internet problems when I use firefox as opposed to google chrome, for example. I have issues streaming videos, but not if I stream them full-screen. But I definitely can't make it go away by pressing on the screen. It just has to be something related to my video/graphics card... Maybe thats hard-ware related, but there isn't anything physically wrong with my screen itself.
I have also recently had trouble doing Windows updates and I'm not sure if its related... My computer turns on from hibernation at 3am tries to do an update and then forces a restart (but ultimately the update fails).

what OS are you guys running on ?
my u330 is on windows7 ultimate 32bit, and I have seen no white bars on my display...
anyway, maybe you could try install some new ati drivers, they will also update intel gpu drivers...
check out here on win7 u330 topic
drivers should work on xp/vista/se7en

I also have this problem.
It happens now with BOTH intel and ATI cards activated.
Also can see a horizontal flickering discolored bar at the bottom of the screen when displaying on an external monitor via VGA port at 1280x720.

same thing is happening to me and it is very very annoying.
i'm running windows 7, reinstalled a few times, updated with latest drivers.
I actually have already payed $160 to have my screen replaced by Lenovo after my previous screen starting falling apart from the casing. so if this is a hardware issue, I've had it with lenovo.
So yeah between this and the battery life being completely horrible, lack of promised updates, the U330 is the worst computer I've owned.

this is NOT a software problem. It is hardware for sure. I, as many, have used the temporary fix of pressing just below the bar and the screen returns to normal. I have inserted a folded tissue paper in between the screen and computer portion and it helps as well. As I mentioned in a previous post, it does it when hot or warmed up.
This truley is a design flaw with the housing around the lcd. It appears to be much to flexible and bends inward enough so that the screen connections become loose. I have since stoped carrying it around so that nothing can apply pressure to the top when closed and it now sits at home and works fine with the less occasional white bar flicker that is easily fixed with a quick pressing just under the bar.
I had called Lenovo and they said the repair cost would range from 150 to 300 since I am out of warranty. Most likely 300 so I won't bother. Very dissapointing to see no support person in this post. I use nothing but thinkpads at work and thought it would be a great idea to go with an ideapad for home. I will second guess that notion when it's time to get another laptop.

Well the white flashing vertical bar is happening to me too. Happens even at post so it is definitly a hardware issue. Between my chassis being crooked, screen being washed out, poor battery life, how long it took to fix the windows 7 video card sleep issue, and now this; I will probably never buy a lenovo again.
To Lenovo: I used to recommend you to my Friends. A couple of them even bought laptops from you. I will no longer recommend your brand to others.

It's been a very bad experience for having purchased a Lenovo U330 Laptop, I am quite sure that I am not alone with this problem of Blinking / Flashing White bar in the middle of the screen, however, my story is very long and it implies the magnitude of disappointment I had for buying such a poorly designed laptop, in order to make my story structured, I will just add numbered list below with all the steps I have taken, It is a very long story, but If you have u330 you must read on and share your experience, here we go.
I am sorry for having thought of buying a Lenovo Product!!!

Given the number of replacements you've had, it makes me wonder if it is the LCD's ribbon cable, and not the LCD. The line does indicate an issue with the buffer, but given that 3 LCDs have gone down this path, it leads me to believe that there is an overly-high voltage on your video line that is causing the LCD controller to fault.
This means you'll need to send it to Lenovo again. However, given that it is under warranty, I would recommend making it clear that your laptop has been through numerous repairs for the same issue, and to have them install a new master LCD cable to further prevent more incidents.
Sorry I couldn't provide a better answer, I've had this happen on notebooks by Toshiba, out of warranty, and the cable costs $60, and requires a bit of work to actually install. It'd be best to leave it in Lenovo's hands.
As well, when you call in, request a repair history on the laptop. Good luck!
