Default Pioneer VSX-D309 No audio with speakers, ok with headphones

I just got the above unit that works with headphones but not with the speakers alone connected. Speakers check fine. Opened unit up and checked all fuses(glass and micro). Fusible resisters in the preamp and amp section are ok too. When power is pressed, the power relay is heard then about one second later the speakers relay engages. No sound.
Could the PAC012A/013A IC'S have opened up?

Anyone encounter this?

Usually if the output ic's are bad the protection will cut in and the speaker relay will not engage, Check that the amp input ass'y board is seated properly
Then check the solder connections on the output ic's
Check if there is output from the suround speakers as well

maybe the outputs aren't turned on? something stuck inside the headphone jack?
