Mainboard diagram for Samsung CA31 Media Box Tuner Receiver - for PS-42P2SB

Howdy !

Does anybody has the mainboard diagram for Samsung CA31 Media Box Tuner Receiver - for PS-42P2SB ? The PSU is working well but due a short on mainboard is clicking - that clicking noise is the PSU's voltage regulator repeatedly shutting off the power and turning it back on. Something is preventing the PSU from delivering it's power to the MoBo so it just keeps spiking over and over.

Mainboard diagram would be appreciated.
