    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.

    I'll update this thread if this changes.

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

    You can see how the connectors are different.

    2.jpg

    #4 3 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.

    new-3.jpg

    #5 3 years ago

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

    4.jpg

    #6 3 years ago

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

    TURN OFF POWER TO THE GAME BEFORE YOU BEGIN!

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

    5.jpg

    #7 3 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.

    6.jpg

    #8 3 years ago

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

    7.jpg

    #9 3 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.

    8.jpg

    #10 3 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).

    9.jpg

    #11 3 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.

    10.jpg

    #12 3 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.

    11.jpg

    #13 3 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.

    12.jpg

    #14 3 years ago

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

    13.jpg

    #15 3 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)

    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?

    Quoted from vid1900:

    3.jpg (Click image to enlarge)

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

    #19 3 years ago

    Bought these already years ago for TZ and STTNG (both sold so nu current experience). Great product, works fine. If yiu see the design it looks really durable and solid. He also makes the best replacemetn baord for TZ-clock

    #20 3 years ago

    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.

    #21 3 years ago
    Quoted from dgpinball:

    Fixed, thanks!!!

    Quoted from Rock914:

    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!

    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.

    #24 3 years ago

    @vid: You are and will remain the greatest - many many thanks so much. Anybody in the world could have written a review better than you ....

    #25 3 years ago

    Thanks for doing this review. I read all your reviews and they are always incredibly helpful!

    #26 3 years ago

    Awesome review vid, and awesome product Ingo!!

    I'm really excited that I'll be offering these here in the US for Ingo, and as a pre-order/show special, Ingo and I will be offering them for only $20 with any anyPin purchase at a show. They will ship in about 2-3 weeks.

    Look for them on my site soon for US orders and across the country at a pinball show near you!

    This time lets do a WPC-95 installation.

    WPC95_1.jpg

    #28 3 years ago

    First we remove the cable that runs to the DMD.

    WPC95_2.jpg

    #29 3 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.

    WPC95_3.jpg

    #30 3 years ago

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

    WPC95_4.jpg

    #31 3 years ago

    Double post.

    #32 3 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.

    WPC95_6.jpg

    #33 3 years ago

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

    WPC95_7.jpg

    #34 3 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.

    WPC95_8.jpg

    #35 3 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!

    Thanks for bringing this to our attention, Vid. I just ordered one for the large Sega dmd my Maverick.

    I was emailing with Ingo and he explained that for my game the dmd saver will connect to the dmd controller board on the back of the dmd. I'll be able to tap into the 5v right there, too.

    Also, from what I understand, the saver board doesn't just reduce voltage it reduces the duty cycle of the pixels so they have to work less time thus increasing the life expectancy.

    This is a little than when I replaced the Zener diodes in my F-14 to reduce voltage and prolong the life of those numeric display. Same effect of prolonging the display, just a different way of doing it. At least that was my understanding.

    My current display is bright and I want to keep it that way since these large dmds are expensive to replace.

    #37 3 years ago

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

    #38 3 years ago

    I have a Lord of the Rings Limited Edition. I thought STERN used a different system than the 2003 LOTR ? Am I wrong . If not . What type should I order ? Thanks a million .

    #39 3 years ago
    Quoted from RobKnapp:

    You need "Version 1" for LotR.

    I do not want to "destroy" vid´s review with my pics, because vid is a much much better photographer and writer than me. Send me a PM and I will send you some pics in advance.

    Can you make a pic of the connector on the display-board, where the flat-cable is put in?

    #40 3 years ago

    Quick question on these. Should we use them on a ColorDMD display or are they safe to last "forever" already and this product isn't necessary for them??

    #41 3 years ago

    Colordmd does not operate on high voltage.

    #42 3 years ago
    Quoted from calvin12:

    Ah, perfect. Thank you for answering my question so simply

    Okay got mine installed today on Maverick. Just finishing up my shop job so I was delayed on installing it. Anway, installation was a breeze and it works perfect. Thanks, Ingo!

    Here are the pics from my install...

    Unplug ribbon cable from J2 on the DMD control board.
    pic1.jpg

    Attach DMD Saver Board
    pic2.jpg

    Re-connect ribbon cable to the DMD saver board
    pic3.jpg

    Attach power connector.
    I got my +5v from the original 5v line that came down to the DMD. Since I had replaced it with the better connection, it was just hanging there unused...so I put put back in use.
    pic4.jpg

    Full view of the back on DMD with all connections made.
    pic5.jpg

    Powered on.
    pic9.jpg

    Flipped the all on switch on the DMD Saver Board to get all the dots to light up. This was how it was set.
    pic6.jpg

    Dialed down the brightness.

    #46 3 years ago

    Does this help eliminate hiss noise from Dmd I have a sttng and when the Dmd animations have more "on" pixels there is more of a electric hiss than the when there is less on pixels for a frame

    #47 3 years ago

    Yes the buzz seems to be less when the brightness is toned down.

    #48 3 years ago

    I'm tempted although I have a red rubylith over my Dmd and plan on putting a comet glare eliminator, so hopefully it wouldn't be too dark... the Dmd hiss is the last real thing I wish I could eliminate.

    #49 3 years ago

    trying to find a link to buy it on the german website or lockwhenlit.com not seeing a place to buy it specifically, will be contacting them via email, but if anyone knows where a page might be let me know.
