Great and quick support. The maual was exactly what I was looking for and my problem
solved. Many thanks.
;
Very good service Within one day i received a pdf of the users manual and electric circuits so I was able to measure the different voltages in the printed circuit and find out the fault Payment was also reliable and easy.Without the manual i could not have repaired.So thanks to "Search for a manual"

you are doing great job guys.....my father ask me to find out the schematics of Sony KV25R1D to sort out the problem ..(he was electrical technician, and excperianced with TV and simillar stuff). finally he found the cause and change all necessary parts....now he has got working old dog..and is very happy!!... thank you all.. NB..he also saved the repair cost.

Perfect. Received my manual within 24 hours. Clear scan of the manual I needed. No problem.

Item as described, very well detailed manual with complete schematics. I've received the download information shortly after payment, very good support.

[3] Downloading Sequence
A
� Downloading the firmware to the AUDIO DSP
Downloading the firmware to the AUDIO DSP is performed in 4 sessions. 1. After reset of the AUDIO DSP is canceled, DSPCS# is set to �L.� Then transfer of the initialization program 1 starts. 2. After the transfer is completed, it is checked that DSPCS# is set to �H.� Then DSPDREQB# is set to �L.� 3. DSPCS# is set to �L.� Then transfer of the initialization program 2 starts. 4. After the transfer is completed, it is checked that DSPCS# is set to �H.� Then DSPDREQB# is set to �H.� 5. DSPCS# is set to �L� then transfer of the initial values starts. 6. After the transfer is completed, it is checked that DSPCS# is set to �H.� Then DSPDREQB# is set to �L.� 7. DSPCS# is set to �L.� Then transfer of the program for the main unit starts. 8. After the transfer is completed, it is checked that DSPCS# is set to �H.� Then DSPDREQB# is set to �H.� Downloading is completed. DSPCS# (Pin 50)
B
SPICLK (Pin 53) SPIOUT (Pin 55) DSPDREQB# (Pin 27) Approx. 110 msec Note: The above-mentioned pin numbers are those of the IC202 (SOUTH CPU). Transfer of the initialization program 1 Transfer of the initialization program 2 Transfer of the initial values Transfer of the program for the main unit
C
� Downloading the firmware to the FPGA
1. The FPGRM is set to �H.� 2. It is checked that SD2_OUT is set to �H.� 3. Transfer of the FPGA firmware starts. 4. After the transfer is completed, it is checked that DONE is set to �H.� 5. After a wait of 1 ms or more, FPGARST# is set to �H� (released). Downloading is completed. FPRGM (Pin 38) SD2_OUT (Pin 36) SPICLK (Pin 53)
D
SPIOUT (Pin 55) FDONE (Pin 37) FPGARST# (Pin 46)
Transfer of the FPGA firmware 1 ms or more
Approx. 200 msec Note: The above-mentioned pin numbers are those of the IC202 (SOUTH CPU).
