Toshiba 50L1350UC No Backlight

[rikrikrik13]

Hi, I got this Toshiba TV without backlight.

Flashlight test : Yes I can see the image
Voltage test on L1+ : turn on tv, backlight flash for 1/2 second, voltage goes to 90v then 76v
Tried to disconnect PWN : No more backlight flash, voltage won't go higher then 76v on L1+


What you guys think? bad led or something else?

hi, I don't know what kind of picture you need. I can post a picture of the blank screen if you want :p

Just kidding, here's a picture of the power supply taken from the internet

I know this is a common issue, that's why I asked without pictures. All the voltage seems fine.

I saw somewhere a way to fix that if we bridge some terminal, but I can't remember
