Lenovo y50-70 thin flashing horizontal white lines, warranty problem

In random locations, at random times, my screen will flicker white lines across it with varying frequency. 

It because most frequent when at high RAM usage, just turned on, or charging at full battery for awhile. 

I tried sending it back once for repairs, but after a two month wait, it failed. I requested another repair, but tomorrow being my deadline, I believe I am unable to send it back once more. I attempted to contact warranty support, but after filling in my serial number thousands of times, the site believes I am possession of a Vibe series C phone. Is there any way I can fix this issue?

 

Thanks in advance.

Hi One3 , 

 

 

Welcome to the Community Forums.

 

This solution may help from this article :

  1. Update BIOS to V3.03 9ECN43WW (or later version).
    http://support.lenovo.com/us/en/downloads/DS100998
  2. Update the Intel VGA driver.
  3. Change the Panel Self-Refresh setting to “disable” in the Intel HD Graphics control panel. (some versions do not have Panel Self-Refresh setting, skip this step.)

If the issue persists, hardware defective is highly detected. Please contact Lenovo local support center for hardware troubleshoot.

 

If the serial number would show mismatch from the website,  verify again from the label or use the auto detect feature but if that fails , provide a direct call to tech support . You may have the issue also documented that this behavior is an issue you noticed before warranty expires specially if the above solution did not work.

In regards to your suggestions, I believe it is a hardware problem as I have already attempted to do a full restore as well as update my drivers. However, could you explain the process by which I access the detect my device application?

If it even does during starting up or in bios its a sign of bad GPU VRAM or RAM(hardware fault)....... Smiley Happy

Hi One3 , 

 

Greetings. 

 

You can type in or serial number from the label sticker and check on the warranty lookup website .

On the warranty site is also a tab (red square box with arrow) to click "Detect my product " for the auto detection.

 

I hope you were able to call in tech support before the date even just to report the symptoms . 

Likewise , try to procure the purchase receipt since it would be useful in manually updating your covered warranty. 

 

Update us. 

 

Regards
