If I do a digital re-tune the programmes/channels are available ... However after powering off the TV set , they are lost again ( at least I suspect this is the reason) . Is there a battery backup memory system used to store the tuned channels and a battery requires replacing or is this a symptom of a board problem. I notice other threads refer to this problem but not answer appears to be forthcoming ... Any technical help would be appreciated ... thanks</P> Sat, 02 May 2015 16:41:41 GMT glowworm 2015-05-02T16:41:41Z https://community.sony.ba/t5/other-tvs/techical-help-requested-kdl-32w5810-quot-programmes-not-stored/m-p/1929201#M23580 <P>TV is a few years old now and has started coming up with "Progammes not stored message" ....
