Default Schematics for portable player Thomson TM 9670

Hello everybody in Russia,
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 schematics or service manual for this player.
Thank you in advance for any help.

Zdrastvujte,

Ivan from SLovakia
