Tesla B90 szalagos magnó (ó azok a szép (?) idők) nyomógörgőjére lenne szükségem, vagy javításához szeretnék tanácsot kérni
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

Olvastam Pásztor kolléga két hete írt topikját,kipróbáltam a kódfejtő programot.A problémám az,hogy a kódot - ami esetemben 0961 - hogyan vigyem a készülékbe, amin csak 1-től 6-ig számozott kezelő gombok találhatók. A készülék azonosítója:GM 0300T5473526.
Segítségeteket előre köszönöm!
