    Hey all! I have a Diner that won’t boot at all. I was told that it was working just recently and when the batteries were replaced, it stopped booting. GI are on but no display and no attract mode. We do get a test bong but that’s about it. I reflowed solder on the power supply and CPU headers and then even touched up solder on the ICs. Any idea what could be the culprit? Thanks! One of the pics shows a chip that looks a little toasty, not sure if it would be an issue though

    Quoted from KenLayton:

    Go directly to the power supply board and measure the DC output voltages.

    Will do. What am I looking for here? Haha sorry I’m learning

    #5 3 years ago
    Quoted from PINTEC:

    bong sound indicates music board is booting with required 5V 12V and -12V voltages present

    Ah, good point. Anywhere I should check first?

    #7 3 years ago
    Quoted from GRUMPY:

    Check these 3 test points.
    [quoted image]

    One lead on the ground braid, and one on the TP, right? on Diode test? And what measurements should I be getting? Thanks!

    #9 3 years ago
    Quoted from GRUMPY:

    Set meter for DC voltage. Black to ground braid, red to test points.

    Gotcha, Am I checking for a beep?

    #12 3 years ago
    Quoted from GRUMPY:

    Nope, tell us what the meter reading is.

    Will do

    #13 3 years ago

    I will conduct measures at the test points and get back to you all!

    #14 3 years ago

    Just to clarify, do I obtain these measures with the game powered on or off??

    #16 3 years ago
    Quoted from GRUMPY:

    It would be hard to measure power with the power turned off.

    Hahah, just want to make sure

    #18 3 years ago

    Got the test point readings!

    TP 1: 05.1 (normal)
    TP 3: 11.7 (normal)
    TP 4: -14.7 (incorrect)

    I think TP4 is the issue! Could it be that bridge rectifier 1 is the issue since it’s in TP4’s circuit?

    #20 3 years ago
    Quoted from GRUMPY:

    TP -4 is fine.
    Now find the 5 volt and ground TPs on the cpu board. Measure these with the volt meter.

    Okay gotcha. I hate to be trouble but could you maybe explain how I’d do this? This is something new for me!

    #22 3 years ago
    Quoted from GRUMPY:

    Turn on game. Put meter on DC volts setting. Put red lead the CPU 5 volt test point. Put black lead on the CPU ground test point. Let me know what you read.

    Okay, thanks! Is the tp2 a ground?

    #24 3 years ago
    Quoted from GRUMPY:

    Left is the 5 volt test point and right is the ground test point.
    [quoted image]

    Huge help! Thanks

    #25 3 years ago

    Just out of curiosity, what would you guess could be the issue at this point? Have we omitted the Power Supply from being the issue? Thanks!

    #27 3 years ago
    Quoted from keith20mm:

    You are needing to determine if the power supply 5v output is getting to the cpu board test point.
    What you read will tell about the condition of the wires and connectors between the power supply board and the cpu board.

    Thanks!

    #29 3 years ago
    Quoted from pinballinreno:

    Did you check for any loose or accidentally unplugged cables?
    Bad or loose fuse?
    Just maybe its something simple?

    Oh my god, it could totally be a fuse. The owner of the game said he checked fuses but I never actually checked myself haha

    #30 3 years ago

    Then again, I think it’s something else. I checked all connectors and even reflowed solder

    #33 3 years ago
    Quoted from PinballManiac40:

    Once you establish 5v is at least 4.8v on the CPU board, please report what is the state of the blanking and diagnostic LEDs on the CPU board.

    Okay will do.

    #34 3 years ago

    I haven’t been able to get out there to take the measurement yet but, I have an account of the led flash sequences. Upon initial start up, the left most LED stays on, the middle LED blinks 5 times, and the far right LED blinks 10 times.

    #36 3 years ago
    Quoted from PinballManiac40:

    You still need to measure the 5v on the MPU. If it is good, sounds like there is a bad part on the board. What all work was done to the MPU? Just wondering to see if it can be potentially related the error codes you are currently seeing.

    Gotcha. Upon removing the MPU, it appears everything was in tact and untouched. Traces were perfect and no hack work was done. I’m wondering if there is a bad component somewhere (if it isn’t a wiring issue)

    #37 3 years ago

    Before I go out to measure, is there anything I should look for if I can confirm there is proper voltage? I just want to minimize the number of times I have to go out there

    #40 3 years ago
    Quoted from ChrisHibler:

    Well sir. Good advice provided in this thread.
    Let’s hear about that 5V on the MPU.
    Happy to help.

    I will report back to you sometime tomorrow regarding the 5 Volts. Thanks!

    #41 3 years ago

    Looks like we have 5v on the CPU! So I guess we are looking at a bad component on the board. I will give ChrisHibler ’s number to him! Thanks!

    #42 3 years ago

    Looks like he is not down to send them in! Is it possible you all could walk me through where to start? Maybe common culprits on the board? I feel confident in fixing it, just need some guidance on this era system 11

    #44 3 years ago

    I recommended sending them in! But he is still on the fence. We found that the F3 fuse keeps constantly blowing. What could this be?

    #45 3 years ago

    It only blows when a connector is plugged in!

    #46 3 years ago

    Unplugging J2 allows the game to boot! No display

    #49 3 years ago
    Quoted from mof:

    Progress! Looks like you may have things isolated to the master display board.

    shot in the dark:
    With the power off -- check for a short on U19 UDN7180

    Sounds good! Since I don’t have the schematics in front of me, what is U19?

    #52 3 years ago

    Gotcha! Well without J2 plugged in, the game starts just fine. We just don’t get a display

    #55 3 years ago
    Quoted from mof:

    "Testing the UDN7180/UDN6118 Chips and Score Glass for Shorts."
    good luck ! DMM set to diode test... 7 * 2 tests per chip... hunt for a difference!

    Thanks so much, man!

    Quoted from ChrisHibler:

    U19 is a UDN7180, which is obsolete, pricey, and hard to find. I have a few around here that are "pulls" from boards with bad glass.

    Ohh, gotcha.

    #56 3 years ago

    So black lead on a ground and red lead should read 0.7V on each leg?

    #58 3 years ago
    Quoted from ChrisHibler:

    Yes. You can compare that readings from the suspect 7180 to others on the board. The bird has several of them.

    Thanks!

    #59 3 years ago

    So there was one leg on U19 that had a far lower reading than all of the other legs on U19 and U20. Do we have a short? If so, should I recommend him buying a new display?

    #60 3 years ago

    In other words, would buying a new display be a good idea? I think he just wants the easy way out

    #63 3 years ago
    Quoted from ChrisHibler:

    Well...if he wants the easy way out, then sure...new display.

    Thanks all! I learned a lot from this thread. Red would look killer

    #68 3 years ago

    Got it connected! But we get this...

    #70 3 years ago

    He sent this! It could possibly be a bad ribbon cable maybe? I believe everything is hooked up okay

    #72 3 years ago

    We will try this! Thanks! I was trying to walk him through it but I think we miscommunicated

    #73 3 years ago

    He said he this is the way he has it. The bottom display works fine and the upper display is messed up

    #75 3 years ago
    Quoted from PinballManiac40:

    That is correct. If pressing the segment test on the display shows all digits work correctly on the top and bottom display, either that ribbon cable is bad or the MPU. Could flip the ribbon cable at both ends to see if the results change.

    We will try! Thanks!

    #77 3 years ago

    He tried a ribbon cable from another game and go the same result. Any ideas? Thanks!

    #80 3 years ago

    Pushing the segment test and all displays go on like normal

    1 week later
    #81 3 years ago

    Definitely not the ribbon cable. Anywhere else?!

    #83 3 years ago
    Quoted from PinballManiac40:

    Need to see a picture of the MPU below the battery pack to be sure there is no battery damage to U41. Above the battery pack looks great.

    I will get a pic!
