Replace IC209 or IC302 on main board.
3-1-2. How to troubleshoot (Countermeasure)
1) Please check VCC MICOM_3.3 VA of IC302 pin48.
If it doesn't work, check 3.3 VA from IC209 pin1.
If it doesn't work, check 5.3 VA input voltage from IC209 pin2.
If 5.3 VA is working, change the IC209.
2) If 3.3 VA is working, check the MPEG reset of micom pin8, power control pin 9, 10, 11.
If it doesn't work, change the IC302.
3-1-3. Service hint (Any picture / Remark)
