Thomson cs-700-as mini hifihez keresek rajzot, javítási "kézikönyvet"
Segítséget köszönve: FEJO
Hello everybody in Hungary,
I am looking for schematic diagram of portable player THOMSON TM9670.
When I connect an USB drive into the machine, the normal supply voltage 5.5V drops to approx. 2.0V in dependency of each usb drive. The player reports that no usb is connected.
I found out that power supply circuit comes from transistor D882L – from pin No.3 which is base pin. This doesn’t make any sense to me. I would expect it should be connected to collector or emitor pin. Therefore I need schematic diagram or service manual for this player.
Thank you in advance for any help.
Regards,
smith666

Javítanék egy Thomson DPL570 gépet
Egy csatorna zárlatos.
2SD2559 nem találtam sehol.
2SB1659 van a HQ-nál
2SC4137 van a HQ - nál
Biztos javítottak már sokan hasonlót.
Lehet ezt pótolni valamivel?
Vagy valakinek van elfekvő , esetleg tudnak beszerzési forrást?
Segítséget előre köszönve: Öreg T.
