Hi I have recently moved and my tdt worked perfectly in my old apartment. I have set it up in new place and I have sound but no picture? Can anybody tell me what I have done wrong :-) thanks

Might just be that the aerial isnt good enough.

We have a 5 meter arial and its only good enough to get 7 or 8 of the channels at any one time, fault of the big mountain at the back of us. However up in Mijas (7km away) they can get all channels on an indoor aerial.

If it has a scart lead between the box and TV give it a wiggle, it may have a bad connection, best to use an HD lead.

if it is a set top box, then sound but no picture, or picture with no sound is usually a SCART cable issue.
Pull them out at both ends and reinsert.
If that does not work, try another - sometimes you may find that one of the pins in the cable has been forced so will not make contact correctly.

IF you have a HD TDT receiver, the make sure the HD cables, or component cables or SCART cables (whichever way you connect) are all correctly inserted.

If it is all built into the TV, then perform a channel rescan.

Isn't there also a correct way round on some scarts? That is one end MUST go in TV and one end MUST go in TDT?

Not on standard SCARTs.

BUt yes, some scarts are "receiving" and others "sending", which you can tell as they say so on the ends of the cable, and each side does not have the full compliment of pins

Hi thanks for your responses..it turned out to be a setting on the TV!!
