The camera has developed a fault in playback where there are grey bars at regular intervals horizontally across the picture in play-back. These were not there when I checked what I had recorded at the time. They are present when I download to the PC. The playback is in SP mode. They are not present on the low quality video on the Sony Memory stick.
I am not very expert. I put a different tape in today and the first video snippet I took did not replay at all, so I tried another bit of video and went to replay and it showed me the first snippet, still with grey bars.
Is it broken

or am I being stupid?
