Solved Lenovo AIO Screen Flickering

Hello,



my Lenovo Ideacentre Flex 20's screen randomly began to flicker a few days ago. It does so in a pulsing motion at roughly five second intervals consistently (meaning the flicker will last for five seconds and pause for five seconds), with this behavior mainly affecting the top portion of the screen. Upon starting my computer, the flickering only starts once Windows has fully loaded and begins with a small, barely noticeable spasm but after a few minutes progresses into a full blown rhythmic screen wave.



As far as external influences go, my computer was never dropped, hit or had any contact with water. The unit is basically brand new and never moves from my desk. Furthermore, my Ideacentre has never been in contact with any other device or anything with magnetic properties for that matter.



I would love to hear what a tech guy or someone knowledgeable with Lenovo products has to say. Does anyone have experience with this issue or had a similar problem? I'm hoping it might be a software thing... Any help with this issue would be greatly appreciated.



Thanks for reading,

John

rebooting into Safe Mode should rule out a software/driver issue if the problem doesn't repeat itself.
how old, that is, is it under warranty still?

Thanks for your reply, @Bruce. I tried booting it in safe mode but it made no difference. Unfortunately, this unit is no longer under warranty and it's starting to seem that paying for professional help might be inevitable... If you can think of anything that might help though, please let me know.

I don't think you have a lot of options. Well, not cheap ones that is.
Safe Mode just runs the core essentials to get Windows working, so screen wise, no driver would have been used and you probably noticed the resolution was on the chunky side.

that leaves hardware - the LCD panel itself, the data ribbon running through the hinges or the graphics adapter on the motherboard.
and as we are dealing with laptops, unless you can do it yourself, things tend to get expensive, quickly.
or more importantly, more than the unit is worth and on par to going a long way towards a new one.

food for thought...

I hear you. That's all way above my pay grade anyway so I'm probably just going to leave well enough alone until I'm forced to take her into the shop. Regardless, thanks for all your help, @Bruce.
