For some years now I have happily operated a SONY RECORDER RDR-HXD870 paired with a SONY BRAVIA TV 40EX523 set for FREEVIEW. Situated in Cambridgeshire we receive signals from the SANDY HEATH transmitter.  Recorder is Hardware version 435 and Software version 115.

On Friday 19 July when attempting to set up more Timer Recordings using the Recorder Digital EPG, the latter flashed up briefly in a format not of the usual style/font and started to populate with information and then went blank. A normal single Click on the System Information key produced nothing and it took a second click to obtain the usual screen choices. The only way to now set HDD recordings is via the tedious Timer method. Later I noticed that the Recorder display was showing UPDATE and this continued overnight and all day today ! The Recorder would accept no input from the handset and the only way to access the existing recorded programmes was to briefly turn off the power and then restore and navigate to the System Information screen with Title List etc.

I wondered if a System Update had become corrupted in some way and, being cynical, wondered if it was linked to the main TV Channel updates that have featured all last week for the SKY 950 series HD channels ! For the main broadcast channels there has been an irritating reminder each time at switch-on for a choice of Channel 950,951 etc with the Default set at Yes, requiring a physical handset change to No. 

It all sounds like a Software Update gone wrong, but how do I undo it ?!
