Main PCB Trouble Diagnosis
9-6. POWER PCB Trouble Diagnosis
Although X-SUS / Y-SUS / SCAN / DATA COF are checked, but still the set does not operate, and then check if the following Power PCB s Trouble Symptoms appear. After unplugging X-SUS / Y-SUS PCB s Power Connectors(P101A, P201A) and checking remaining voltage, there still exist several tens of remaining voltage. When output condition of Power Module is set to LOW-Voltage, output voltage table lists 4~10 are NOT normal. Or when set to HIGH-Voltage, output voltage table list 1~3 are NOT normal. ( Refer to 4-3-2 ) When output condition of Power Module is set to LOW-Voltage, output voltage table lists 4~10 are normal. But when set to HIGH-Voltage, output voltage table list 1~3 are NOT normal. ( Refer to 4-3-2 ) After turn SET on with Remote Controller when output condition of Power Module is set to HIGH-Voltage, the LED turn Green but the Power Shut Down happens after 2~3 seconds.
If high voltage(Vsus, Vyer, Vadd) measured from Power PCB is different from that of Optimum adjusting Voltage LABEL, readjust the voltages referring to 6-2-1. Adjusting Power PCB
