I'm trying to help a friend troubleshoot a problem with his JH 16 (76 ver).  He accidentally unhooked the PSU cable from the audio PSU box and didn't power down before trying to replug.  Small arc and pop and now the Play, FF Rew are gone along with the shield control and the MVC lamp. 

Does anyone have the schematic for just the card shown in the pic?  It's part # PC2500CO213.  I've searched through the schematics that Analog Rules has and cannot find this board.  Apparently they have a later version with a different supply.

The transistor with the red circle has no markings on it.  No clue what it is.
