I should probably find a service manual for my Sony
VPC-1272 projector;
it's power supply intermittently sings in the most annoying way. Like,
louder than the projector's fans.
The serive manual for our Sony digital TV set doesn't incldue the SPU
board scheamtic :-(. On one page it claims this is because it was an
OEM'ed module, on another it's becuase field repairs to the PSU are
prohibited for safety reasons. Whatever...
You do get scheamtics of the receiver PCB, complete with BGA ICs and the
like.... But not of the bit you actually have a chance of fixing with
nornal tools...
