Onkyo TX-RN809

[nataf10]

Hello friends.
I have a ONKYO TX-NR809 Home Thea' .
The unit go to protection mode immediately when I power the unit.The relay click can be heard and the fluorescent display lit for a second and then power go back to Stby mode.
I checked all the output power transistors for any short circuit but all looks good,tried to disconnect other board to get the power turn on but NOTHING!
Any idea/solution will be welcome.
Thanks in advance

Remove the large plug on the right hand side of the unit which provides power to the power amp section (with the 7 drivers). This should bring the unit on, albeit with no sound.
