Satellite Pro P300-23L - horizontal lines over taskbar

I have a Satellite Pro P300-23L laptop.
Yesterday evening there suddenly appeared, approximately 30 horizontal thin white lines over the taskbar (in fact over the bottom half inch of the screen).
The top 3 or 4 of these lines seem to pulse in a rapid, regular pattern.
Now, I can barely see the icons in the taskbar, nor the Windows start button in the bottom left hand corner.
I had read on another forum that the problem may be due to a "grounding" issue.
The charger jack plug is actually broken and I have repaired the wiring myself, but that was some time ago, so it is possible that a connection has come loose or is now shorting out something, causing this effect.
I have ordered a new charger but meantime would appreciate any assistance to confirm or deny that this may be the problem.
Any advice on how to rectify this?

Hi
If the issue would be related to the AC adaptor then this lines should NOT be visible using the notebook with battery power. Right?
Therefore it would be really interesting to know if the same lines are visible if the AC adaptor is not plugged in.
But I think this is not related to AC adaptor. In my opinion its either an display problem or graphic card issue.
Therefore you should connect an external monitor in order to check this.
If the same lines are visible on external monitor, then the graphic chip is affected… otherwise it could be a display problem.

Thanks MasterG, good point..the lines are still there when the AC adapter is disconnected, so that blows my theory out of the water. I never actually thought of checking it...duh!
However, I have followed your further advice and connected it via the HDMI cable to my LCD TV and the lines are no longer there, so it must be the display. Can it be rectified?

Well, it looks like a display issue… but I would recommend checking this issue with Toshiba ASP in your country. It’s always better if an expert would confirm the reason for the issue. If the display is faulty, you will need to replace this and if the warranty is not valid, the fix can be expensive.
