Working on a Philips 42PF5321D/37 42" plasma. When plugged in, the green front panel LED comes on for 3-4seconds while several relays click. After 5 seconds, the unit goes into a stand by processor fault mode. The red LED blinks 6 times, waits a few seconds, then repeats. I have the service manual, which seems to suggest the 5V supply for this fault, but am having trouble tracking down anything obvious. I have the power supply board out and there are no obviously blown caps, etc. Can anyone suggest anything to check?

6 = Signal Processor (IC 7150) error

7 = Total failure

8 = Internal RAM error (Microprocessor IC 7000)

10 = NV memory (IC7088) addressing error

11 = NV memory (IC7088) size error

12 = Histogram (YUV) (IC 7770) error
