Thompson Top Up TV Recorder problems?

Where do I start?
Our Thompson refuses to switch on at first attempt. We have to unplug and then it will come on.
Our facility for favourites just disappeared overnight about a month ago.
Channel 22 Ideal World - we have no idea what programmes are showing until we go into them. All the descriptions disappeared a week ago. This only happens on this station.
For the last few months it's refused to record Casualty.
Now other programmes are not recording, it seems to be choosing what we watch.
It's had funny moments since we purchased it just over 12 months ago but now it's all the time.
Would welcome any ideas to put it right or does anyone know an email contact at Thompson. Don't want to phone because of the cost.
