1-1-2. How to troubleshoot (Countermeasure)
1) Please check Vcc voltage. (pin A4, A10, D4, D14, P4, P14, U5, U6, U9 of IC101  3.3 V)
If 3.3 V voltage doesn’t come out, Replace IC602.
2) Please check Vcc voltage. (pin A9, E9, J4, J14, P9, P12, T10, U4 of IC101  1.2 V)
If 1.2 V voltage doesn’t come out, Replace IC603.
3) Please check Crystal Frequency (X101)  24 MHz and Replace it.
4) Please check RESET voltage. (pin T11 of IC101  3.3 V)
If 3.3 V voltage doesn’t come out, Replace IC106 and R161.
