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.
Item as described, very well detailed manual with complete schematics. I've received the download information shortly after payment, very good support.
Really good and well scanned. File is complete the full service manual for 5$

2-4. Input Level Range Confirmation and Level Setting
Measurement Equipment Audio signal generator Audio distortion meter, BKPF-202 Preparation 1. Connect each equipment. (Refer to Fig.1 in Section 2-1-2.) 2. Turn on the power of the main unit (PFV-D20/D50/D100A/D200A/D300) and warm up for ten minutes. Procedures 1. Provide an analog audio signal of 1 kHz, +4 dBm from an audio signal generator to the ANALOG IN AUDIO 1 connector of BKPF-205. Provide the "L" output signal from BKPF-202 to an audio distortion meter, and read the level.
BKPF-205 ANALOG IN AUDIO Input to "1" Input to "2" Input to "3" Input to "4" BKPF-202 DIGITAL IN AUDIO Provide an output signal from AES/EBU OUT 1 of BKPF-106A Provide an output signal from AES/EBU OUT 1 of BKPF-106A Provide an output signal from AES/EBU OUT 2 of BKPF-106A Provide an output signal from AES/EBU OUT 2 of BKPF-106A BKPF-202 ANALOG OUT AUDIO "L" becomes effective. "R" becomes effective. "L" becomes effective. "R" becomes effective.
2. Turn 1RV102 (A-4) counterclockwise until the clutch is activated and clicks. Confirm that the level is less than 0 dBm. 3. Turn 1RV102 clockwise until the clutch is activated and clicks. Confirm that the level is more than +18 dBm. 4. Turn RV102 so that the audio output level is +4 ± 0.1 dBm. 5. The ANALOG IN AUDIO 2 through 4 connectors are also the same in procedures as described above. Confirm and adjust the volumes below according to steps 1 through 4. . ANALOG IN AUDIO 2 connector : 1RV202 (A-5) . ANALOG IN AUDIO 3 connector : 1RV302 (A-6) . ANALOG IN AUDIO 4 connector : 1RV402 (A-6)
