EDP cable was disconnected while testing new screen. No image, no bckl
Macbook Pro 2019 A2159 Board 820-01598
EDP cable was disconnected while testing new screen. No image, no backlight
- Done SMC and PRAM reset. Nothing changes.
- Tested other functional aftermarket and original screens. Nothing changes.
- Don’t have other EDP cable for testing.
- No shorts anywere.
- SMC_LID / Hall function works as the touchbar works ok.
- Image fine in external monitor
- Tested EDP conector and all components.
- PPVOUT_S0_LCDBKLT: 0v
- MOSFET Q8400: G: LCDBKLT_EN_L: 12.5v (doesn´t drop)
- MOSFET Q8401: 0v all pins
But what scares me are this two signals that come from the processor and it’s 0v on both:
EDP_BKLT_PWM and EDP_BKLT_EN
Any ideas?
Appreciate the attention and help
