Was it left on standby since you tried it earlier?

My trusty old Sony Trinitron would be fine if left on standby, but after being switched off at the mains for a while would look awful, and took hours to return to normal.

I won't bore you with an attempt to explain why, other than to say that electrolytic capacitors lose their capacitance as they get old, but can self-heal (partially) if left with a voltage across them for a while. That's my theory - but it's probably wrong...

Pretty much right, the surfaces and electrolyte get tired and damaged but recover slightly as you said.

Not an electronic engineer but an old Royal Signals clerk tech .

Ok update - yesterday after all the advice on here had unplugged and disconnected everything from old tv and left it for possible disposal!! After hubbie turning back on last night - it is still working ok today and I have now reconnected digibox and wii...... who knows. Will post back if problem recurs. Kinda thinking it might do and that something starting to fail but will wait and see......

I reckon the defocussing caused by that compensated for the drift in HT voltage that put the TV out of focus.....
