Hello
Van 2 ilyen rögzítőm is. Az elemet kicseréltem rajtuk, de nem javított a helyzeten.
Hiába állítok be dátumot, 28 másodperc elteltével visszaáll a kezdetire 2001.01.01. 00:00:00...
Mi lehet vele, mit nézzek meg?!
Köszönöm
NR

Üdv!
A csatolt képen látható fejhallgató szárvezetője széttörött. Hogyan lehetne ezt jól megjavítani?
A torott_burkolat.jpg-n látható a feladat.
Amik eszembe jutottak, mint lehetséges megoldások:
- ALU ragszalaggal körbetekerni, ha nem nyúlik a szalag
- vékony drótot körben beleolvasztani a műanyagba. Plomba drót lenne szerintem a legjobb a bordázottsága miatt.
- szögletes acélgyűrűt ráhúzni
Pillanatragasztót, epoxit elvetettem, szerintem hosszabb távon széttörnének.
Ami a nehézséget adja: olyan NDK-s megoldást valósítottak meg, hogy a latkep.jpg-n piros nyillal jelölt csavarfej kapaszkodik bele a nyíl végén látható fülbe. Kb 0.5-1 milliméter műanyag tágulás esetén a csavar feje kiugrik a kapaszkodó fülből és annyi.
Ehhez hasonló "ötletességgel" a Wartburg ajtónyitó mechanizmusában találkoztam, de az nem prémium termék volt.
Bármi ötletet örömmel veszek!

There is no service manual of the Yamaha KX-250, anyone? I have fixed the mechanism of this unit, replaced the capstan motor (bad quality shreeking one with a better one), replaced the belts and works perfectly fine. Perfect audio, everything works great. However after testing it many times I reassembled the unit and did another test. Some tick noise is present in the audio.
The tick noise is present when executing a function, for example REW (most worse of all), FF or PLAY (only a few spikes randomly), also when using the remote. It is not a problem of the mechanism (motor) or a ground issue or something like that, disconnected it and problem still exists. Maybe it has something to do with static electricity because I have used the unit without HEAD cables attached to the mainboard (head input pins floating) however the pre-amplification circuit is working fine except of the noise. There are two IC's in this circuit, UPC1330HA head selector and a LA3161 pre-amplifier.
The LA3161 is a 2-channel preamplifier that has a circuit to reject ripple. Is it possible this IC is damaged (because of a (static) spike) and because of that the ripple rejection is no longer working? When I replace this IC the problem is solved?
Any ideas or do have some people any experience with this or recognize the sound behaviour discription? Anyone who can point me into the right direction?
Many thanks for any reply.

Sziasztok!
fent nevezett gépnek keresem a szervizkönyvét, google-t már végig bogarásztam de nem jártam eredménnyel....
Kérem ha valaki tud nekem segíteni nagyon hálás lennék érte!
Tippeket előre is köszönöm!
