Video Sender problem

idnotfree

I have got a video sender (Thomson Model VS650) that I am using to see TV from our bedroom. But after every 2-3 days, it loses connection and the pcitue disappears. The only solution I have seen is that if I take out the scart from the sender and put it again after few minutes, then it works. Is it normal with all the senders or mine is bad?

Also, I have noticed that when Microwave is used in the kitchen, then also picture becomes bad.

Has anybody else seen this problem? Is there a workaround to this?

Thanks,
Rick
