ASUS p8h61-m LX3 Plus main board memory can not be repaired

ASUS p8h61-m LX3 Plus main board memory can not be repaired.

ASUS p8h61-m LX3 Plus motherboard memory, but the dud4 anti-static tube and yellow circle of the 6 pin chip, troubleshooting.

Machine model: ASUS p8h61-m LX3 Plus.

Fault phenomenon: no memory.

Maintenance process: the customer said that sometimes the computer can be turned on, sometimes it can’t be turned on. This time, it can’t be turned on directly.Test each big VCC normal, test memory SMB 3 VCC smbdata 1.19v is not normal.
