To Next PageTo Next PageWhy is there no power supply to my Panasonic SA-PT150GCP?
If your Panasonic Home Cinema speakers have no power, verify the AC cord connection for any opens or shorts. Inspect the fuse F1 on the SMPS Module P.C.B. Check the supply voltage to the Main P.C.B. from the SMPS Module P.C.B. (+5V/+7V/2.7V). Ensure the cable connection between the SMPS Module & Main P.C.B. is secure. Check the DC voltage (+9.1V).
What to do if my Panasonic Home Cinema speakers have no audio output?
If there's no audio output from your Panasonic Home Cinema speakers, first check the speaker connections and solderability. Then, check the amplifier IC circuit (audio output) and the power supply to the amplifier IC.
What to do if my Panasonic Home Cinema speakers cannot read CD/DVD disc but spindle motor is spinning?
If your Panasonic Home Cinema speakers cannot read a CD/DVD disc, but the spindle motor is spinning, check the laser drive circuitry for voltages and current. Specifically, check the CD Laser Drive and DVD Laser Drive, comparing voltages and LD current with a known good DVD Module P.C.B.
What to do if my Panasonic SA-PT150GCP Home Cinema speakers cannot read data from USB?
If your Panasonic Home Cinema speakers cannot read data from USB, check the USB connector & FFC. Also, check the LSI O/P and the IC supply (+5V).
What to do if the Panasonic Home Cinema speakers have No FL Display?
If the Panasonic Home Cinema speakers display is not working, check the supply voltage, referring to Item 1 checking points. Also, check SYS6V to IC2018, the oscillator circuit, and the soldering condition.
Why is there block noise during play on my Panasonic Home Cinema speakers?
If you are experiencing block noise during playback on your Panasonic Home Cinema speakers, check the SDRAM address and data bus signal.
Why is there Jitter out of specification on my Panasonic SA-PT150GCP Home Cinema speakers?
If the jitter is out of specification on your Panasonic Home Cinema speakers, check the LD current and the OPU (consider changing to another unit to confirm the operating condition).
What to do if disc not spinning on my Panasonic Home Cinema speakers?
If the disc isn't spinning, the traverse isn't moving, or there's abnormal movement with the traverse and spindle on your Panasonic Home Cinema speakers, check the connection from the DVD Module to the Traverse unit. Also, check the motor driver circuitry for voltages and control signals, comparing with a known good DVD Module P.C.B.
Why is there no TOC / Long TOC on my Panasonic SA-PT150GCP Home Cinema speakers?
If your Panasonic Home Cinema speakers are showing 'No TOC' or 'Long TOC', check the motor driver circuitry (+5V). Also, check the laser drive circuitry (Voltages & current), and the LSI IC connection to motor drive circuitry. Compare these with a known good DVD Module P.C.B.
How to troubleshoot distorted picture or abnormal sound during initialization of Panasonic Home Cinema speakers?
If you experience a distorted picture or abnormal sound during the initialization of your Panasonic Home Cinema speakers, check the SDRAM address, data bus, CLK, and other control signals waveform. Also, check the video signals and the audio DAC circuitry, comparing these with a known good DVD module P.C.B.
