Yoga 2 Pro Flashing/Raining Green Pixels

2014-11-21, 1:12 AM

Hi everyone, I hope you can help me with something. About a few months ago I noticed that when I first turned on my computer (and whenever there is a dark background) I see green pixels and sometimes red pixels too, on the dark background and it's driving me insane. Here is a video of what I see:

It only happens on my laptop monitor, not with any external displays.

Does anyone think they know what could be causing this and have any suggestions?

EDIT: It seems to be pixels of every colour and not just green.

I'm having the same issue. I tried to update the video driver and the problem persists.

Questions:

1. Does it happen both with the charger plugged in and on battery?

2. Does it happen at different screen resolutions? (3200x1800 & 1920x1080)?

3. Does it happen both when the laptop is cool vs. hot?

 

Sounds like it could be a driver issue or could be a noise issue internally.

It doesn't matter if it is hot or not. Plus, the rainning of pixels like an old TV, I also have a very annoying flickering that is driving me crazy. I feel like it is a memory or a processor malfunction. I'm actually not sure about what is causing the issue. I bought my laptop in the USA at BestBuy. The first Yoga 2 Pro I got had a problem and I returned it to the store. Now this one lasted a little bit more than a year and now it is facing this issue. What can I do now since I moved to Brazil?

It happens in all resolutions and whether the charger is plugged or not. When it is connected to the TV, I can see the pixel rain in the laptop, but I can't surely see it on my TV. It does not flicker too though.

You can see pixel at the loading screen (one with "LENOVO") and in BIOS.

Yes, I do can see the pixels when I'm accessing bios and when the computer is starting with just the Lenovo logo. It does not seem to be just a driver problem.

So, as my warrany has expires I decided to disassemble the screen and to replug the cable. It helped, but I'm not sure for how long it will last. BTW, I sent my yoga 2 to Lenovo once as I had different screen issue, and I found this cable duct tabped :). Also I've noticed that plastic at the corners under the screws was broken and I never dropped my laptop, so either that's how they fixed it first time or how reliable screen mount is.

 

On a different note, it would be nice if Lenovo provided me with couple extra scews for bottom part, as one of them came of and got lost.

So did you just disassemble the screen part of the laptop? Do you think the problem can be the cable? Which one? Where did you replug it? Please more details! And I appreciate your attention and answers.
