1. I have Changed U9850 and the results are still the same, Discovered that the IC is working on a Good Known Board and it Displayed on My DONOR(board) so the U9850 was working, But I just Swapped anyway.
2. U1200 should create EDP_IG_BKLT_EN - 0v but it is 0v

the Device had no liquid Damage or any Sings of Corrossion, No physical Damage, i have inspected through the microscope.

Voltage AND DIODE MODE measurement (red probe on ground and without power connected), I have tested With SCREEN CONNECTED.

U8500

1. 5,1v (0.350)
2. 3,3v (0.560)
3. 5,1v (0.350)
4. 5,1v (0.350)
5. 5,1v (0.500)
6. 5,1v (0.500)
7. 5,1v (0.676)
8. 0v (GND)

U8501

1. 3,3v (0.315)
2. 3,3v (0.560)
3. 3,3v (0.315)
4. 3,3v (0.315)
5. 3,3v (0.330)
6. 3,3v (0.330)
7. 3,3v (0.612)
8. 0v (GND)

U8510

1. 3,3v (0.329)
2. 3,3v (0.535)
3. 3,3v (0.695)

U9801 on this IC I will Post Lines I am thinking they have abnormal Voltages

(5) GMUX_IOEXP_ADDR_SEL - 0v

(21) USBC_HPD_DET - 0v

(26) DP_INT_EG_HPD - 2,5v

(27) EDP_MUXSEL_OVR - 0v

(29) TP_BKLT_BOOST_EN - 0,47v

(31) TP_BKLT_FAULT_L - 0,9v

(32) DP_INT_IG_HPD - 3,3v

(34) EDP_IG_BKLT_EN - 0v (weird right)


Different Lines Measured

DP_INT_IG_HPD - 3,3v

LCD_MUX_EN - 3,3v

PP5v_S0SW_LCD - 5,1v

PP5V_S0_ALSCAM_F - 5,1v

PP3V3_S0SW_LCD - 3,3v

EDP_PANEL_PWR_EN - 3,3v

PPVOUT_S0_LCDBKLT - 55,35v

PANEL_P3V3_EN - 3,3v
