Please clarify how you are feeding the TV, is it from the aerial (antenna) or cable, or using a scart lead etc. It sounds like it is not seeing the video input but is seeing the audio. If it is from a scart lead the lead may be faulty, or if some other route then please clarify. I hope I have been of help but please do not hesitae to to ask if you have any further questions. I appreciate your vote if you appreciate my reply.
