Trust Tytan2.1 ( 19019 ) nem kapcsol be! IC40 (848J43) ez milyen ic lenne?
Sziasztok!
Most került hozzám hogy nem lehet bekapcsolni, de nálam két napig ment, de most nem indul el. Bedugva hagyva 1 óra után elindult, de csak két napig ment, most már több óra után sem indul el. A kondikat cseréltem a tápban, de a 6lábu ic-ét IC40-848J43 nem tudtam beazonosítani? Rajzot sem találtam hozzá, a lapon lévő szám: LX.PCB2.1CH-1.V2.4.
Miért nem indul el a tápegysége, mert amikor ment akkor rendesen szólt?
repair sony amplifier str-de254
Want to share: Have downloaded the schematics from this forum to help repair the amplifier of a friend. Turned out that Sony decided to route the earth through the chassis, even the earth between the various supplies. When one takes the main board out of the chassis and switches the amp on, there are up to 20 volts difference between the eart (and hence reference) of the pre-amps and the main amps. Luckily the amp goes into protection but from a design point of view it is not nice to rely on screws and aluminum face plates to conduct up to 0.2 amps of current from one supply to another. What I did is solder wires to every eart point and connected them on the main board to make it stand alone and not rely on conducting current through the chassis anymore. Bad design, simple repair but took some digging in the schematics to find out what exactly was going on!
Sony CD javítás
Vettem donornak egy Sony CDP770 típusú, amúgy elég komoly hifi cd lejátszót. Szép állapotú a készülék, annyi a baja, hogy magas hangok alapzajként aláfestenek a zenének. Egyébként kitűnően működik a gép, nincs lelkem elbontani. Néztem a kapcsolási rajzot, a HF fokozat annyira "rövid", hogy kizárt ott bekerüljön bármi zaj. Egyébként is állandósult a dolog, szólhat bármilyen lemez benne. Ötleteket szívesen fogadok, hol keresgéljek.
Numark MP103 USB CD játszó kimenetek némák
Üdv! Keresem a Numark MP103 USB tipusu CD játszó manuálját. (De miért nem itt?) link A kimeneteken nincs jel , panelen égésnyomok. Sajnos a bele teljesen más mint a 102-es modellé. Köszönöm Mack
