Complete original Service Manual in good (scan) quality!
;
Very good manual. Plenty of service information including alignment instructions. Clear circuit diagram. Excellent, thank you.

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
Replacing a Drive FET (Q800)
1. When replacing the Drive FET, you must also replace its heat conductor cube, because the heat conductor cube is removed along with the FET. 2. After removing the FET and its heat conductor cube, solder a new Drive FET to the PCB. Make sure the FET is in the proper position before soldering. 3. Attach the heat conductor cube to the FET as instructed below. 5. The solder melts and binds the FET and the cube securely. Then, slide the soldering iron along the PCB surface to cool the soldering down ( r ). If the heat conductor cube comes off from the PCB or the soldering can be seen on the top of the plate, the soldering has not been successful. The soldering must bind the heat conductor cube and FET securely (see the figure 3).

s How to Solder the Heat Conductor Cube
1. Place a piece of soldering wire (about 2.5~3.0 mm long x 0.6mm diameter) into the FET hole on the PCB ( q ). 2. Place the heat conductor cube on the PCB surface beside the FET hole. The rounded surface of the heat conductor cube must face upward (as shown below) ( w ). 3. Slide and drop the cube into the FET hole so that the rounded surface of the cube is now horizontal (as shown below) ( e ).

6. After soldering the heat conductor cube to the PCB, check the level of PCB surface. The surface of the heat conductor cube must be free of flux and solder. It must be flat and smooth, at the same level as the PCB surface (as shown below).

4. Place a heated soldering iron onto the top of the cube, using an iron tip 900M-T-3CF. Hold the soldering iron in position for about 5 seconds (See the figure 2).
Fig. 4 s How to Check the Heat Conductor Cube Surface
1. Slide your index finger along the PCB surface (as shown below) ( t ). The surface should be flat and smooth. If you feel that the surface is uneven because of solder or flux, grind them using meshed copper or re-solder the cube in order to flatten the surface.
