Good morning, the service manual you sent me was perfect.
Your service and answering are excellent.
I recomend this service.
Best regards.

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!

ADJUSTMENT
Item 3. Mechanism Adjustment Adjustment Method, Adjustment Value First, reset by pressing both VOLDW and SRC keys at the same time and boot up the system in Test Mode. Display Setup screen with the FUN key, and press ADJ key for making adjustment. Note 1: If adjustment becomes impossible as a result of having input incorrect values, clear the E2PROM first and then conduct the adjustment. This can be done by resetting while pressing VOLDW and OPEN/CLOSE keys. When this is done, the machine also loses the mechanical positions. Therefore, this must also be adjusted again. In MONO Scope screen, confirm that the right and left positions are uniform. If they are off a little, use VR200 (HYOUJI) to adjust the right and left to be uniform. (Adjust to less than one dot difference.) If the difference is much too large, adjust from the beginning of X35 again.

1. X25 Circuit Adjustment Specification (K : For North American Markets)
Item 1. Video detection coil adjustment L303 Adjustment method / Adjustment value 1. Turn VR301 [RF-AGC] fully to the right. 2. Apply DC2.0V to TP [IF AGC] (IC300 pin36). 3. Feed fo=45.75MHz, Mod=1kHz, AM60%, Level=100dBµ into TP [IF] (A100 pin8). 4. Observe the TP [VIDEO] (IC300 pin8) waveform on an oscilloscope and adjust L303 for maximum level. Conditions ･ No ANT signal ･ If the waveform is clipped, slightly increase the DC voltage. ･ AC range
Maximum
2. Audio detection coil adjustment L300 3. S-METER adjustment VR300 4. RF AGC adjustment VR301
5. Diversity free run frequency adjustment VR400
1. Turn VR301 [RF-AGC] fully to the right. 2. Feed fo=41.25MHz, No Modulation, Level=94dBµ into TP [IF] (A100 pin8). 3. Connect a voltmeter to TP [SIF] (both ends of R314) and adjust L300 for 0V±0.01V. 1. Turn VR301 [RF-AGC] fully to the right. 2. Feed a 30dBµ 11CH color bar RF signal into the ANT input terminal. 3. Audio (P/S ratio -6dB) no modulation. 4. Connect a voltmeter to CN300 and adjust VR300 [SMET] so it reads 3.5V±0.05V. 5. Set the RF signal to 70dBµ and adjust VR301 [RF-AGC] so that the voltmeter connected to CN300 reads 4.5V±0.05V. 1. Connect a frequency counter to CN400. 2. Using the remote control unit TV/NAVI button, switch to adjustment mode. 3. Adjust VR400 [15kHz] so as to obtain 15734±10Hz.
ï½¥ No ANT signal
･ Postpone adjusting VR301 to prevent AGC having effect at 30dBµ. ･ Ensure the RF AGC adjustment is performed after the S-METER adjustment. ･ No ANT signal ･ Test mode
