7.2. Power
Main set power ON Power do not turn ON
(No FL display) Power ON by remote control OK Check the 30P FFC connection from Button Left P.C.B (P1500) to Main PCB (CN2506)
Check the 22P FFC connection from Button Left P.C.B (P1502) to Multi Control PCB (P1600)
Check standby supply PW_SYS3R3V = +3.3V
Voltage check across the power switch. When button PCB power switch S1500 is press 0V, release 3.3V to 3.5V
Voltage check 1) +F to -F (filament voltage across FL pin 1 to pin 44),PW_VEE
Voltage check of IC2103 Pin 10 Output of L2101 = +12V (Refer Check Point 7 in Figure 1-1)
Check the 13P FFC connection from Multi Control P.C.B (P1601) to FL Display PCB (P1700)
Tact switch operation check (S1500)
Power ON by remote control NG Check the 30P FFC connection from Button Left P.C.B (P1500) to Main PCB (CN2506)
Check the 22P FFC connection from Button Left P.C.B (P1502) to Multi Control PCB (P1600)
Check the 13P FFC connection from Multi Control P.C.B (P1601) to FL Display PCB (P1700)
IR sensor operation check (IR1730).
Check the power supply output of SMPS Module to Main P.C.B
Check the AC inlet and AC cord
Check fuse cut
Power input but turn off immediately Power off the unit during FL blinking of F76 (250ms ON/250ms OFF).
Power off the unit during FL blinking of F61(250ms ON/250ms OFF).
(IC3001, IC3101, IC3201, IC3301)
Power input but FL display error Check Connection of Bluetooth
Fuse cut After replacement, cut again at outlet connection The primary side of main power supply abnormal Check the continuity of primary side power circuit
After replacement, cut again at power on The secondary side of main power supply abnormal Check the continuity of secondary side power circuit
FL display checking Check the all segments display by Doctor Mode Some FL segment not lighting Failure of FL Display (DP1700 & DP1800)
Key operation checking Power on unit using remote control or power button FL display "Hello" Press key buttons on unit
NFC checking Power on unit using remote control or power button Press selector and choose "Bluetooth"
Check and do setting of NFC. Off the set and tap phone on NFC logo on unit
