Supported "dts", and were able to purchase Pioneer DV-S9(an early version) which was a model of machines that there was remodeling to multi-region easily (there is not need to purchase a kit) .
Actually, multi-region tried to change into, and show the record.

At first confirm a version of firmware.
Do the following operation by the state that do not put a DVD disk in.
    1. Push a "Menu" button of a wireless remote controller.
    2. Select Initial. (Push "Enter" of a wireless remote controller or "1".)
    3. Push a "Display" button of a wireless remote controller.
Region number, a version of version MPEG 2 decoder of firmware are displayed at a point then.
(if it is Ver. 1.100/8, Ver. 1.118/8, Ver. 1.168/8, Ver. 1.178/8, Ver. 1.180/8, Ver. 1.218/8, remodeling to multi-region seems to be possible.)

From this place, real remodeling begins.

In this remodeling, soft soldering for a tip part is necessary.
Because it is small work, as for the person without confidence, the one that does not do will be passable.
As for the model of machines that remodeled, there is the case that be not received a support of a maker.
(because a shock is big when has broken because DV-S9 is not cheap)

At first take off an upper cover after confirming that a power supply is let out of an outlet (be taken off power supply cord at the back).
Upper part screw (8 place) uses a hexagon wrench, and take off.¡¡Because size of a wrench is small, attention is necessary.
There is the fear that has spoiled a screw that this wrench does not employ person whom size fitted.¡¡In case of me, used a thing of 5/64 inches (about 2mm).
Take off a screw of a back panel side (3 place) with a normal "+" driver.

Took off an upper cover
Take off a cover plated copper in the center.
Take off a cable fixed with a holder to a cover, and take off a screw of 5 place with a "+" driver.
Do gloves of thinness, and work then when does not want to add sebum to the copper surface.
In case of me, used gloves of the cotton which used when treated LaserDisc.
But do, and work becomes hard.
In particular please pay attention catches a screw and harms, and not to drop.

Took off a shield

The I side of the main base which excluded shielding includes LSI of "PD3381A".

Add wiring to this tip part standing in line sideways.

    Connect a base land in IC side of the fifth tip part to IC of the fourth tip (probably, condenser) from Handa part and the top of an other side from the top of a tip part standing in line beside PD3381A.

[ wiring 2 ]
    Do soft soldering of wiring to a base land the side of the sixth tip part (IC side) identically from the top, and fix an other side to a screw installing a base like a photograph of the lower part.

With the above remodeling is the end. A screw leaves shielding, and put back a cable, and a screw leaves an upper cover.
When a screw leaves an upper cover, tighten with six angles of wrenches, but because a screw is special, do not seem to break a thread, and attention is necessary.

If crosses and rose, join by a power supply cable, and connect a monitor.
Be equal to or less than by the state that does not put a DVD disk in equally that confirmed a version first || operate.
    1. Push a "Menu" button of a wireless remote controller.
    2. Select Initial. (Push "Enter" button of a wireless remote controller or 1.)
    3. Push a "Display" button of a wireless remote controller.
In this state, a region should be still a thing of "2".
Do the following operation here.
    4. Be longish a little, and push a "Condition" button of a wireless remote controller. (There is no change to a screen then.)
    5. Displayed Region number changes at realtime when pushes Region number to hope for with a wireless remote controller.
    6. Push a "menu" button, and be ends.
