    . Technical Specifications.1-2 . Safety Instruction, Warning 50/60HZ Power consumption button to confirm, then screen will display : Firmware Upgrade Programming, Please Wait. Do not Switch the Player Off ! 4) The upgraded disc will automatically out when files coping complete, then take out the disc. 5) About 1 minute later, the trace will automatically close when upgrading complete. B. Read out the software versions to confirm upgrading 1) Power up the set and open the tray door. 2) Press button to check the software information. The software version and other information are display on the TV screen as follows: BE Version: DVP3XXXXX_XX.XX FE Version: DCX.XXXXXX.XX.XX DSP Version: DSP.XX Region Code: X 3-1 Caution: The set must not be power off during upgrading, Otherwise the Main board will be damaged entirely. 4-1 Spindle motor does not move Yes Yes No No No No Yes Check whether “RFA5V” (+5V) voltage is normal. Correct connection Check the RFA5V power supply Check/Replace Q2 Q3. Check/ Replace U1. Have no focus 1. Check U1 182pin FOCUS_PWM signals 2.If there are F+, F-, T+ and T- signals output from U7. Check/Replace the loader Yes Yes No Go Check whether laser voltage (2.3V for DVD & 1.9V for CD) on Collector of Q2 and Q3 Check the FFC connection between 24P and the loader. 1.Whether voltage on pin 129 of U1 varies between 0 and 3.3V (3.3V for CD and 0V for DVD), 2.Whether peripheral components are eroded or badly soldered. Trouble shooting chart Motor no move FOCUS_PWN waveform Remark: Trouble shooting chart for DVP3140/XX4-2 The power can not be on or off Go Ye s Yes No No The power cant be on or off Yes Repair the power board Check the power supply on the power board is normal. Check/Correct connection Whether the connection to K301 is broken. Correct the connection Replace U1. No No Yes Yes Check if the CON301 on the front board to CN5 on the decoder board is in good contact. Whether there is 0V and 3.3V voltage difference on Pin 94 PCON of U1. Trouble shooting chart Remark: Trouble shooting chart for DVP3140/XX4-3 All output voltages on the power board is 0V or deviated.No No No Yes No U1(PIN 8 - Drain waveform) Replace F1 Replace C1&C2 if D1, D2, D3, D4 are normal. Check/ replace U1. Check whether U1 are eroded. All output voltages on the power board is 0V or deviated Check whether there is 300V on C1 and C2. Check whether 100KHz oscillating signal on Pin6 of U1 Check if +5V, , +12V and -12V are short. Check whether the components in the short-circuit voltage are defected or eroded. Yes Yes Yes Yes U1(PIN 3 - RC waveform) Check whether F1 is blown Trouble shooting chart Remark: Trouble shooting chart for DVP3140/XX
