Page 1 of Toshiba SD220E - Image Problems?

I recently purchsed a MR Toshiba SD220E and have two recurring problems with the image:
1. A faint line moving across the screen from left to right)- this seems to happen all the time.
2. A brightnes flickering between light and dark at the top 20% of the screen (this only seems to happen on certain scenes).

Can anybody provide any insight/help?

Thanks.
