NO BOOTING

When you plug power cord and turn the unit on, LED won’t turn on, the unit won’t read disc normally.

1-5. Please check MAIN board IC201 signal and its peripheral circuit.

1) Please check if output voltage 5 V from IC201 pin8, pin19 is normal.

If output voltage 5 V is not normal, please check 5 V power circuit of MAIN board.

2) Please check every signal connected between IC201 and IC601, especially including F+, F-,T+, T-,
SP+, SP-, SL+, SL- signal to drive MD.

If F+, F-, T+, T-, SP+, SP-, SL+, SL- signal is not normally output, please check if IC201 is in failure.

If IC201 signal is not normally output, please check connection MD of CN202 to MD if is in failure.

2) Please check every signal connected between MD to IC601, especially including RFA, RFB, RFC,
RFD, RFE, RFF signal from MD.

If RFA, RFB, RFC, RFD, RFE, RFF signal on IC601 pin1 ~ 6 is not normally output,

please check connection MD of CN201 to MD if is in failure.
