Trying to trouble shoot an issue with a Sony Bravia V series IDTV with built in freeview.

No issues with the freeview|HD picture over the UHF aerial, but if I plug in an analogue video source over composite or component I have major diagonal hatching happening on the picture. The source is either a Sony DVD player or a kids video game.

If I unplug the UHF aerial connection the hatching goes away.

Anyone here seen this problem before and have any ideas on a fix?

This is hardly conclusive, but to me it sounds like your TV may have a defect that is causing interference between the UHF and analog inputs.

Sounds to me like a standard groundloop issue but the noise is coming from a switching power supply rather then a mains one.

Easiest solution is to go get a cheap power strip with an antenna surge supressor in it and use that to ground the antenna before it gets to the tv. you can confirm if its a ground loop by only touching the outside of the antenna cable to the tv somewhere grounded like the side of the VGA plug or something. Careful, I have had cases where there is enough voltage between them to give a not-so-mild tingle.
