Default philips 37pfl7403d error 11

last few days I have a problem with my Philips TV 37pfl7403d Q529 1E LA
at the begining of the problem i had dark screen with the sound and the remote worked fine. this problem was intermitant ie the image back from time to time
today when I switch on the tv I have a click and the red LED blinks twice.
I opened the tv and connect the pin sdm to ground sdm in order 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 ie 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 measurements?
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

ps: i am francophone. so sorry for my english
