No picture or sound is output.
(1) Check if the MHL cable is detected.
When the MHL cable is connected, can "High” be seen for 4pin
on N1101 (8U-310116)?
(3) Check power supply (8U-310116) .
Are 3.3V supplied to N1701 5pin?
Are 1.2V supplied to N1701 6pin?
Are 5V supplied to N1101 12pin?
(4) Check RESET.
Is RESET waveform confirmed in N1101 (8U-310116) 8pin,
when the power is turned on? (If the waveform is not the
reference waveform, proceed to NO.)
(5) Check Control signal (I2C).
Is waveform confirmed in N1101 5pin/7pin (8U-310116), when
the power is turned on? (If the waveform is not the reference
waveform, proceed to NO.)
(6) Check the DDC waveform.
Can the waveform be seen for 9pin/10pin on N1101 (8U-310116)?
(2) Check the VBUS(5V) output.
When the MHL cable is connected, can "5V” be seen for 1pin on
N1701 (8U-310116)?
The MHL cable is defective.
Q804, Q805 and surrounding circuitry (8U-
310115-3) are defective.
The power supply circuitry is defective.
8U-310116
U1708 (3.3V)
U1709 (1.2V)
Q1725 (5V)
The RESET circuitry (8U-310116) or U802
(8U-310115-3) is defective.
Replace the new parts.
Q1108 (8U-310116) or the pattern is
defective of I2C line.
U800 or U802 and surrounding circuitry (8U-
310115-3) are defective.
U1707 and surrounding circuitry (8U-
310116) are defective.
