The 40v4000 supports 1080p so when the PS3 auto-detected the display settings it set the XMB to 1080p, the 32v4000 supports 720p but the PS3 still thinks its connected to the 40v4000 so it is trying to output 1080p which is out range of the 32v4000. Go to the display settings on the PS3 and auto-detect the display settings again.
