AMD Radeon HD6320 screen flickering

Hi all,
I’m an owner of a Sony Vaio VPCYB3V1E. I have my laptop for one month and unfortunately I have a problem I’m unable to solve so far.
3 weeks ago I've noticed the following weird thing – once I leave my laptop and not use it for a while the display starts to flicker. A few horizontal lines appear on the top and in the middle of the screen which lasts for a few minutes and then all is back to normal till the next time. Restarting usually resolves the problem for a longer period.

My graphic chipset is AMD Radeon HD 6320 (driver date: 24.05.2011; driver version: 8.861.0.0).
I guess it is some driver or hardware problem, which I’m not able to solve.

Please help me.

 

Did you try updating the video driver?

 

Of coarse.
This is the most up to date driver available according to Sony...

 

Try the latest driver from AMD.

 

Unfortunately Sony does not allow non Sony drivers to be installed.
(Unless modified)

I was hoping for a more constructive suggestions or ideas from people who have experienced this. I've already tried the usual things (like updating drivers).

 

Did you try using the oldest AMD driver available from Sony? It could be a new driver thing.

 

I have to correct myself... there is no driver available on the Sony website.... I've just tried to disable it but I couldn't find the driver so I had to restore my system ....
Can someone give me an older driver for Sony if such is available? As mendioned above I'm currently using AMD Radeon HD 6320 (driver date: 24.05.2011; driver version: 8.861.0.0)

 

I also have a Sony Vaio VPCYB3V1E with AMD Radeon HD 6320 and I'm experiencing the same issue as described by Vaiolina.

The flickering only starts when resuming from a standby or when the lcd screen turns on again. The flickering happens along the borders of the lcd screen. As I'm writing this, the screen is flickering at all borders, but at other times the flickering may just as well be happing only at the bottom or at the right side of the screen.

I have just connected the laptop to my television (Philips 48PFL8404) via HDMI (while the laptop screen was flickering). On the television, there was no flickering whatsoever.

Restarting the laptop reduces the flickering a little bit.

I'm running Linux Mint 12 with the Gallium 0.4 driver (which is open source). The proprietary AMD Catalyst driver gave other problems.

Assuming that Vaiolina runs Windows 7, I expect this to be a hardware problem, and not a software problem.

 

Send it to Sony for warranty repair, the same problem on my ex's Hp Dv2 was actually the graphics card failing

 

I found a solution so far.... just disabled the "turn off display" from the Power options. (set to NEVER)

There is no flickering since then.
And Yes, I'm running with Win 7.

 

Vaiolina, I have the same problem with my VPCYB3V1E. Have you managed to find a permanent solution for this or are still using the "turn off display" settings from the Power options? Any help would be much appreciated. Thanks.

 

If you're getting screen flickering in the internal display but not on a second screen via HDMI, then it's a problem with the screen or its connection, not the GPU or drivers. If you're under warranty, an RMA might be the only way to solve it.

 

or problem with power states or sleep mode.
