Hi' everybody. I have a M1 MBP from 2020 with a liquid damage. CL053 PP3V3_S2_WLBT_ISNS was shorted, replaced and now the MBP is running. I get image on external screen but not on internal. I have tested on other known good display without any image. Testet in known good housing as well - no luck. On the old MB you easily see if it is backlight. But not anymore.
Any suggestions where to look first? I looked at schematics but I can not find any issues. Thank you in advanced.
