HOW CAN I FIX MY THOMSON TOP BOX MODEL DT16300-16?

I DELETED A PROGRAMME THAT I HAD WATCHED
I WAS TAPING ANOTHER PROGRAMME AT THE TIME BUT WHEN I WENT TO WATCH IT THE LIBRARY SAID
THERE WAS NO PROGRAMMES BUT I HAD ABOUT 7 OR 8 PROGRAMMES STILL TO WATCH WHICH HAD JUST
DISAPPEARD I TURNED OFF THE POWER AND THEN
SWITCHED BACK ON I LEFT IT ALL NIGHT BUT IT DID NOT RESOLVE THE PROBLEM.IT NOW WILL NOT RECORD AND IT LIGHTS UP ON THE PROGRAMMES THAT I HAVE SELECTED TO RECORD THE SERIES BUT IT DOES NOT RECORD AND LIGHT DOES NOT TURN OFF AT THE END OF THE PROGRAMME.
