    As plasma DMDs continue to spiral upwards in price, it starts to make serious sense to make them last longer - as in 20x longer.

    Some DMDs are approaching $500 to replace (like the 192x64 Segas).

    If we lower the operating voltage with a replaced diode, we can make them last longer; but sometimes we have to try different diodes on older displays to find "just" enough voltage to light them up.

    Another way to achieve the same effect is to alter the "duty cycle" of the display. Each pixel cell is lit for less time. This allows us to dial in the exact lowest voltage, just before the display blinks out.

    Unlike the diode trick, as the display ages and needs more voltage to light up, you can just turn up the cycle a little more.


    Remember, the DMD Saver can't fix an already dead, completely outgassed display. Nothing can fix that. But it can keep a working DMD going "forever".


    When bright LEDs first started appearing on the market, pinheads went crazy bragging "I did my whole backbox in ULTRABRIGHTS !!!!!!!!11". Of course all that glare on the playfield glass made the games impossible to play.

    So another advantage of these devices is that you can turn down the brightness and get way less glare on the glass from the DMD - very cool.

    So right now it looks like there is no model to support the 128x16 DMD games:

    Star Trek 25th Anniversary
    Teenage Mutant Ninja Turtles

    I'll update this thread if this changes.


    #3 6 years ago

    Here are the backsides of all 3 versions of the boards.

    You can see how the connectors are different.


    #4 6 years ago

    Here is what you get in the kit.

    The PCB, a 5v lead, and a Scotchlock connector.

    A Scotchlock connector lets you tap into an existing wire lead without stripping, without soldering and without a messy bunch of electrical tape. They are used in automotive jobs all the time, like car alarms or stereos.


    #5 6 years ago

    The PCB is all through hole construction, so servicing will be easy if it is ever needed.


    #6 6 years ago

    Here we are going to install on a WPC Williams game - so we are using VERSION 2 for this job.


    (I'll document some other installations latter in this thread)


    #7 6 years ago

    We start by removing the Ribbon Cable leading to the DMD display.

    Note that Pin 1 on the Ribbon Cable has a red stripe.


    #8 6 years ago

    Next, the DMD Saver plugs right into the header that the Ribbon Cable was attached to.


    #9 6 years ago

    The Ribbon Cable plugs into the DMD Saver in the same orientation that it was on the board.

    Pin one matches up to the red stripe.


    #10 6 years ago

    We, of course, want a clean looking installation, so fish the 5v lead behind the boards and cables.

    There are a hundred places to steal 5v from in a WPC backbox, but it makes sense to grab it from the connector on the lower left hand side of the board.

    2 of the pins have 5v available (you can do a sanity check with your volt meter if you want).


    #11 6 years ago

    There are only 3 long wires leading off of J606 and the gray one in the center has 5v running through it.

    Clip the Scotchlock onto the 5v gray wire.

    Slip the end of the 5v lead into the "dead end" of the Scotchlock.


    #12 6 years ago

    Making sure the 5v lead does not slip out of the dead end, squeeze the blade through the insulation of the 5v lead and the gray 5v wire.


    #13 6 years ago

    Lock down the cover over the blade.

    That way there is no need for electrical tape and nothing can short out against the now energized blade.


    #14 6 years ago

    Plug 5v lead into the DMD Saver and your installation is complete.


    #15 6 years ago

    Turn the game on.

    Don't panic if there is nothing on the DMD, as you may have to turn up the brightness to see anything.

    Using a small screwdriver, turn the brightness up until you find the magic spot where the display comes on.

    The dimmer the display, the less glare and of course, the longer it will last.

    The little switch on the DMD Saver will turn on all the pixels. If you used an alligator clip to a 5v test point instead of a Scotchlock, you could test a game's display before you bought it. Another cool feature. (the lines in the picture below are the camera's shutter capturing the refresh of the display. In person, the display looks perfect)


    #21 6 years ago
    Quoted from dgpinball:

    Shouldn't the text say 5V lead, not 12V?

    Fixed, thanks!!!

    #22 6 years ago
    Quoted from Rock914:

    Very cool but i do not like the scotch latch one bit. An easy pass through connector should be built to eliminate user error and a cleaner install, just my opinion.

    Us car audio enthusiasts love Scotchlock connectors, but you are right, there are a dozen ways to skin that cat.

    There are so many game models and brands that this PCB works with, that is could be expensive to include a pass through connector for all of them.

    Off the top of my head:

    You could use an insulated alligator clip and grab power from a 5v test point on the board.

    You could crimp a new J606 female connector, and include the 5v lead.

    You could make a stacking connector.

    Add some pics to this thread if you guys come up with anything clever!

    Quoted from Axl:

    This looks like a great product to save some money in the long run.
    But how to order, and what is the price?
    Can you make a guide on that as well Vid?

    Sorry about that. I did not know what the price was in USD yesterday.

    It's $25 and I've updated the first post to reflect that.

    Until the USA distributors pick this up, order directly from German-Pinball.

    This time lets do a WPC-95 installation.


    #28 6 years ago

    First we remove the cable that runs to the DMD.


    #29 6 years ago

    Next we install the DMD-Saver. There is a version specifically for the WPC-95 systems.

    Although the DMD-Saver says "This side down" you need to install it with that side up. It intends to say that the bottom edge of the Saver, aligns with the bottom edge of the video board.


    #30 6 years ago

    Now re-install the DMD cable. Remember the Red Stripe aligns with Pin 1.


    #31 6 years ago

    Double post.

    #32 6 years ago

    Again, there are many places to obtain the necessary 5v to power the DMD-Saver.

    Connector J606 is probably the most convenient.

    The Gray wires on pins 4 & 5 have 5v.

    You can sanity check with your meter.


    #33 6 years ago

    Use the included Scotchlock to tap into the 5v lead.


    #34 6 years ago

    Plug 5v lead into the DMD Saver and your installation is complete.

    Turn power back on to the game, and adjust the dial for the level of brightness you desire.


    #35 6 years ago

    This particular WPC-95 had a loud buzz, that was actually cut down quite a bit by lowering the voltage to the display.

    An unintended benefit, for sure!

    Please take a bunch of pics as you install it in your Maverick; I did not have a Sega available to document the procedure.
