great video. I had not the same exact issue, but your explanation lead me to find the rp844 to be broken. Replacing it gave me backlight.

Great explanation of the M1backlight circuit Winson. Thank you

Thank you for amazing tutorials. @l2computer310 I’ve got the same model with no backlight. After visual inspection area around UP700 and UP701 has some corrosion (I’ve cleaned with 95% alcohol and then reflow but still same issue). I do not have line PP5V_SW_LCD (diode mode on pin 1 CP712 have O.L) I’ve removed CP712 ,CP711 and UP700 the short still there. What will be next to check?
