"U7090 just pic 6 VIN"
What about pin8???

Just in case, check diode mode at L7095.

There was some liquid damage before and i replaced a bunch of components and just realized that i soldered R7080 instead of on it's own place it was from R7080 pin 2 to r7081 pin 1 my mistake Thank you very much for your help
