Default philips 37pfl7403d

last few days I have a problem with my Philips TV 37pfl7403d the first frame q529
it all started with the image did not appear for the sound and the remote worked fine. this problem was intermitant ie the image back from time to time
today screen there is nothing that works. when I switch I have a click and the red LED blinks twice.
I opened the screen and connect the pin to ground sdm to interpret faults, and I have the red LED flashes 2 times (one long and one short) it turns out that the flashing LED is protection mode which corresponds to the error 11 cad 3v3; High 5V too.
unfortunately startup voltage appears briefly and disappears immediately impossible to make measurements.
bypass the standby is apparently too dangeurex for this type of fault because the component could 3v3 powered grill.

I'm out of ideas.
how to diagnose the problem without action?
how to remove protection without risking any fuck up?
is that anyone has had this problem tell me directly what component incréminer?

thank you for your help
