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

Try to boot in safe mode.

If it still does it, then I must be hardware.Thanks for your reply, Geek-9pm. I just booted the computer in safe mode and it made no difference. From my description of the problem, do you have an idea of exactly what part needs to be repaired / replaced?To me it sounds as simple as the LCD cable to the display needs re-seated and/or replaced...
But you stated it wasnt dropped.Thanks, patio. I'll try to take the suggestion to someone who knows about computers and hopefully I can GET it done without breaking the bank.Any chance the computer is still under warranty?  AIO type computers are generally the most expensive to fix because they tend to use proprietary parts.

It could be something simple such as a loose cable like patio said or it could be the built-in graphics adapter or even the monitor itself.
