Screen Flicker on VGN-S4XP - possible design flaw

caruk — Sat, 20 Aug 2005 22:14:22 GMT

Hello,

I am now on my second VGN-S4XP and it seems to be exhibiting the same annoying problem as the first.

When running on battery (and possibly when on AC power), at random intervals (ranging from 2 to 4 minutes) the brightness of the screen changes for a fraction of a second, creating what appears to be a momentary flicker. Because the problem does not seem to be visible when the brightness is turned all the way up I suspect that the flaw is causing the screen to brighten for a fraction of a second and then return back to its proper brightness.

The first Vaio that I purchased exhibited this problem from the moment it was turned on (with the default software installed). I therefore thought that the first unit was flawed so I returned it and paid to have another one sent to me. Unfortunately the second unit exhibits exactly the same problem.

Since I enjoyed flawless service from my first Vaio (S1XP) and I will not return to the UK, where it was purchased, until after the time when I could return the laptop for a full refund, I would very much like to resolve this problem.

Is anyone else here seeing this problem? How can I have it resolved? Please advise!

Seems to be a common problem with the S series.

Seems to be a common problem with half the bloody X-Blacks Sony ever made. Having it fixed is considerably less than reliable too.

I would have thought that Sony would be sufficiently ashamed of this problem on a premium laptop that they would find a way to fix it once and for all. It really does let down what is otherwise a tremendous product.

Strange that my S1XP did not have this problem but I guess that it has something to do with power utilization.

I¿ll be contacting Sony technical support when I return to see what they have to say.

Thanks for the feedback.

Chris

Guess it's not only on the S-series, noticed it too on my FS215S, on power-up/resuming usage the screen flashes once, kinda creepy like my laptop is falling apart already. Not what I expect for the price I've paid 😞

Hi,

I fixed mine witha Video driver update from the Sony Support area of their website. It was the Nvidia video driver. had not a single flicker since.

Hope it sorts you out as it drive me nuts and the machine was heading for the fish tank!

Just sent my K-Series away for the exact same problem, and to get another problem with faulty memory sorted. Its really irritating, i think its just the connection working itself loose when the screen is opened and closed as well, which should not happen at all
