Default Sony ST-S310 tuner trouble

Hey folks,

i wanted to reuse my old ST-S310 (about 15yrs old) these days. But after a minute or two, the signal indicator falls back to zero and the tuner mutes. Once that happened, i cannot receive any of the stored programmes in stereo nor tune into a new one. When i tune through and come near a station, the indicator rises but when at the exact freq, it falls back to zero and mutes.If i switch to mono, it plays even without any indicated signal. I have to switch it off for an hour to get stereo and then i can repeat it all.

Any idea anyone? Any service manual floating around?

Carefully adjust the discriminator coil. You may also need to resolder that coil.

Default Sony ST-S310

Hi
I have a Sony ST-S310 Tuner which seems to have a memory problem. If I switch it off over night it looses all memorised radio stations. However if I only switch it off for a few hours it keeps its memory OK... Any ideas on this problem anyone as it is irritating to have to manual tune everyday or leave it on all the time.

Help !

pretty much seems like the cap that's buffering the memorys ps has gone weak. But don't ask me which one that is ;-)
