Yashica T-AF -- shutter problem

[btgc]

Hello, does anybody has experience or can point to good resources related to Yashica T-series (I've got first gen) ? P&S "with adorable lens" appears not cutting off shutter, just lens front cover is opening - as expected. Other functions - focusing, advancing, rewind, flash - seem to be working (I haven't exposed film).
In fact shutter has opened exactly two times from about 30 exposures. Seems I'll need to enter it....

After disassembling camera and testing it, pressing shutter doesn't cut shutter at all. Timer releases shutter, just sometimes doesn't - in this case it makes short buzzing noise. It must be science of contacts. Anyway, seller refunded me 50% of purchase price (because shipping back would bring me just 1eur) and shipment now exceeds price of camera 2 times.

Heck, sometimes one looses game, so I did with T*-lens P&S.
