2. Switching power supply board DC5VA part of the circuit maintenance: Figure 8 Schematic, usually due to "431" regulator "817"

optocoupler "1905" transformer caused no adverse 5V output, in addition to burning phenomenon if the insurance burn plates, usually

due to excessive flow resulting in "4007" diode, "4.7UP / 400V" capacitor "274" integration breakdown is bad, replace the bad component

or power supply board can be.
