Troubleshooting for LED Blinking ( 2/4/7/10/13 time blink )
LED blinks
Quick 2 / 4
(only Asia/Latin
FS5**/6** )
7
10
(only FX750-800,
FZ*** series)
13
Quick 2 / 4 blinks is problem about memory access ( IC8900 or IC8000 )
7 blinks is problem about the power line of SUB3.3V.
10 blinks is problem about initialization of FRC IC (IC9000).
13 blinks is problem about IC8000 and software issue.
IN THESE CASES, A BOARD DEFECTS
Detail error
Memory (eMMC: IC8900) read problem
No voltage SUB3.3V detected
FRC_SOS (Initialization of IC9000)
Emergency SOS
(mostly case the memory (eMMC / NAND Flash) IC problem )
