Excellent, fast delivery, excellent product. Good luck!

This manual is for the usa model only. But it is clear
, accurate and comprehensive, including board layouts and schematics.
I found it extremely useful for my mitsubishi dp-86da, but the same diagram would also work for the realistic lab5000 and hi fi 80. Thanks.

Great to have extra resources for Service Manuals, Now days you can really not trouble shoot efficiently without one , Wayne at IRIONS TV & ELECTRONICS REPAIR Clearwater , Fl. 33755 727-446-7955

For five bucks you can barely buy a hamburger. Or for the same five bucks you can buy a service manual. Much more useful. (and better for your health, depending on where you buy your hamburgers).
Yes, there are free manual sites out there, but if they don't have what you want, you have to pay.
And five bucks isn't much. Not for full specs, schematics and adjustment and parts replacement procedures.
My only criticism is that grayscale illustrations aren't well rendered, but I've seen worse.
Schematics and text are clear.
I'll be happy to purchase from here again.

Impressively thorough. Even the simple operators manual helped me "fix" one of the 2 CD players in the unit. This unit reads CD's from the top so they should be installed in the magazines "upside down" from typical CD players. The CD player service manual helped me unjam a stuck carriage because somebody transported the box laying down loaded with CD's. A little lens cleaning & the player now works well! Thanks for you help at a great price! Joe
BKSR-2021 (Encoder) BKSR-2030 (Decoder)
BKSR-2021 (Encoder) Video System The analog composite video signal from the external equipment is input to the COMPOSITE VIDEO INPUT connector and sent to the VCA & Clamp IC (IC106) where the signal level is controlled. The input signal is then sent to the A/D converter (IC135) where the signal is A/D converted and then sent to the Composite Decode IC (IC313). In IC313, the input signal is Y/C separated and converted to the digital component signal. The analog component video signal from the external equipment is input to the COMPONENT (Y/R-Y/B-Y) VIDEO INPUT connector and sent to the AMP & Clamp circuit (Q209 to Q211, Q213 to Q218) where the signal level is controlled and then sent to the Composite Decode IC (IC313). In IC313, the input signal is A/D converted and receives the multiplexing processing so that the input signal is converted to the digital component signal. The digital component signal that is selected by the Composite Decode IC (IC313) from the digital component input signals, is sent to the TBC IC (IC413) where the desired sync signal is selected, and is sent to the Resize IC (IC420) via the Setup Removal IC (IC416), where the component signal is resized to the desired horizontal pixel size. The digital component signal is then sent to ENC3 IC (IC400) where motion is detected, converted to the MPEG picture data by Encode IC (IC405) and recorded on PCI SDRAM (IC1401 to IC1404). Audio System The analog audio signal from the external equipment is input to the AUDIO INPUT 1/2 connectors and sent to the AMP IC (IC600 to IC603, IC608 to IC611) where the signal level is controlled. The input signal is then sent to the A/D IC (IC618) where the input signal is converted to the digital serial audio signal that is then sent to the Selector IC (IC1004). After the digital serial audio signal is output from the Selector IC, it receives gain control at DSP (IC902) and then receives audio compression at MPEG Encoder (IC700). The compressed data is recorded on PCI SDRAM (IC1401 to IC1404) via FIFO (IC706). Auxiliary Data The closed caption data that is superimposed on the video signal is converted to the 2-byte/field data by the Detect IC (IC502) and is recorded on PCI SDRAM via the CPU bus and AUX DPRAM (IC503).
BKSR-2030 (Decoder) Video System The pictures recorded in the PCI SDRAM are read and sent to the MPEG Decoder (IC301, IC331) via the DMA Control IC (IC201), where the signal is decoded to the base band video signal. The video signal system contains the two decoders in order to enable the signal switching with the frame accuracy. The video signal to which the closed caption signal is added at the signal switching circuit is input to the VIDEO Encoder (IC502) where the AES Audio signal is added and is output from the SDI Encoder (IC551) as the SDI signal. Audio System The audio data recorded in the PCI SDRAM is read and sent to the MPEG Audio Decoder (IC603, IC605, IC607, IC609) via the DMA Control IC (IC201), where the signal is decoded to the PCM audio signal from the audio signal. The PCM audio signal is then sent to the DSP (IC708, IC711) where the signal level is controlled. Then the PCM audio signal takes the two signal paths: One path is connected to the VIDEO Encoder (IC502) where the PCM audio signal is multiplexed into the SDI signal. The other path is connected to the Audio D/A Converter (IC813, IC8013) from which the signal is output as the analog audio signal. Auxiliary Data The auxiliary data recorded in the PCI SDRAM is read and sent to the FIFO (IC202) via the DMA Control IC (IC201). The auxiliary data is then sent to the Closed Caption PLD (IC401) where the closed caption signal is created from the auxiliary data, and added to the video signal.
