My sony TV KDL - 32S3000 was manually re-tuned following digital update, but later on some channels (only)appear to re-tune themselves to different channel numbers. Many different x-mitter signals can be received in this area, but auto-tuning wrongly selects west midlands rather than east midlands. Have manually re-tuned each time (four times this year) but this takes in excess of 40 minutes for most channels. Why do the channels change themselves?
