Default Schematic diagram for portable player Thomson TM 9670

I greet everyone in Hungary,
I'm looking for a concept of a portable THOMSON TM9670 player.
When I connect the USB drive to the computer, the normal supply voltage of 5.5V drops to approx. 2.0V depending on each USB drive. The player reports that USB is not connected.
I found out that the power circuit comes from a D882L transistor - from pin No.3, which is the reference pin. It does not make any sense to me. I would have expected that it should be connected to the collector or pin emitor. Therefore, for this player, I need a schematic diagram or a maintenance manual.
Thanks in advance for any help.
