I have a Vaio Pro 13SVP1321S1EBI for almost 3 years and ever since the 2nd month the screen keeps flickering and has green stripes every once in a while, sometimes just for a few minutes, sometimes for days on and off. Here is what happened so far
First 2 years while in warranty:
- Called Sony support they told me it's the Windows causing it, so I went through all the driver updates. Everything was up to date and still did the flickering. I reinstalled the whole Windows 8. After a few days it stopped.
- I upgarded to Win 8.1 and everything was working for months flawlessly, until again it started for 2 days and Sony support: it's the Windows and the drivers for 8.1 are not supported on my device. I reverted back to Win 8, no change.
- Finally the laptop was taken to a service center, and returned back in 2 days: nothing hardware or software problem found, everything works fine. 5 days after return, again flickering.
- Upgraded to Win10, everything was working fine for months long, and didn't have any problem until I had to revert back to Win8 because of Wi-Fi connectivity issues - then a few weeks in again flickering.
Since the warranty ended, again keeps doing it on and off again. Now it's been doing it for 6th day in a row, updates all installed, Win 8 - the device came with it pre-installed.
I connected it to an external monitor and that doesn't do it, it's just the build-in screen, even at startup before even loading the OS.
I have ran out of ideas to try, and useless calling the support because:
