I had been looking everywhere for a proper service manual for this VCR. Everywhere else that has this available for download has a very light version. This is the full service manual with all aspects that would interest anyone looking for the service manual for the AIWA HV-MX100 Worldwide VHS VCR. Great quality (as always). A winner hands down. Best Quality.
;
Top quality manual. Covers all aspects you'd expect in a top quality service manual for this Panasonic VHS VCR. The manual resolution is high. Another top quality manual from the only site worth downloading manuals from! If you're looking for a manual for the PV-9662 VHS VCR, this is the one you'll want to get!

complete part-lists and pcb layout, schematic diagram is good enlargable,
;
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.

1. SGH-D500 RF Circuit Description
1) RX PART
1. ANTENNA SWITCH (U100 SWICHPLEXER) ¡æ Switching Tx, Rx path for GSM900, DCS1800 and PCS1900 by logic controlling. 2. ANTENNA SWITCH Control Losic (U100) ¡æ Truth Table VC1 Tx Mode (GSM900) Tx Mode (DCS1800/1900) Rx Mode (GSM900) Rx Mode (DCS1800) Rx Mode (PCS1900) L L(H) L L H VC2 H L L L L VC3 L H L L L
3. FILTER To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band. - GSM FILTER (F100) ¡æ For filtering the frequency band between 925 and 960 MHz - DCS FILTER (F102) ¡æ For filtering the frequency band between 1805 and 1880 MHz. - PCS FILTER (F101) ¡æ For filtering the frequency band between 1930 and 1990 MHz. 4. VC-TCXO (U101) This module generates the 26MHz reference clock to drive the logic and RF. It is turned on when the supply voltage Vcc(SYN) is applied. After buffering a reference clock of 26MHz is supplied to the other parts of the system through the transceiver pin CLKOUT. 5. TRANSCEIVER (U102) This chip is fully integrated GSM GPRS quad-band transceiver with transmit baluns, loop filters and most of the passive component in it. And also fully integrated fractional N RF synthesizer with AFC control possibility, RF VCO with integrated supply regulator. Semi integrated reference oscillator with integrated supply regulator. RF Receiver front-end amplifies the E-GSM900, DCS1800 and PCS1900 aerial signal, convert the chosen channel down to a low IF of 100kHz. In IF section, further amplifies the wanted channel output level to the desired value and rejects DC.
2) TX PART
The transmitter is fully differential using a direct up conversion architecture. It consists of a signal side band power up mixer. Gain is controlled by 6 dB via 3-wire serial bus programing. The fully integrated VCO and power mixer achieve LO suppression, quadrature phase error, quadrature amplitude balance and low noise floor specification. Output matching/balun components drive a standard 50 ohms single ended load.
