Check the +5V voltage. (HDMI Rx) Check the DDC line. (HDMI Rx)
HDMI Rx [U1000 or U1003] is faulty.
Replace with a new device.
Recheck from check item (2).
If it does not work, replace the PCB.
HDMI Rx [U1000 or U1003] is faulty.
Replace with a new device.
Check for a short circuit in the 5 V line and the 5
V Switch IC [U1002].
If there is no problem, the HDMI Rx [U1000 or
U1003] or the 5 V Switch IC [U1002] is faulty
Replace with a new device.
Check for a short circuit in the DDC line.
If there is no problem, the HDMI Rx1 [U1000] or
