    Monix, if I understand you correctly, 100% brightness is a workaround for the problem. Is that right? I am not able to duplicate your issue here, I am afraid.

    Hello? I guess this isn't getting fixed?

    So if I mess around with the brightness it does effect the flickering.

    Today I turned on the module. No flickering at all. Opened up the settings and was at 100% brightness. I simply touched the dial and turned it to 99% and flickering began instantly. Then I turned it down to 61% and the flickering has stopped. After playing for about 3 minutes, it starts flickering again. Go into settings and turn it down again... now to 50%. Good for about 5 minutes, and flickering again. I have now turned the brightness down as far as possible.

    This is really poor, and I believe it is directly related tot eh firmware. I have checked all the ribbon cables. I have disconnected all modules in my case so this is the only one drawing any power. Thi sis so frustrating as for me the module is really unusable at this point.

    Please provide a firmware update to address this bug. This is not a feature request, it is something that should be high priority!

    Also noticed my screen flickering... same scenario, sometimes awfully, sometime just steady like it should. Already tried playing with the brightness setting... I would say it works but not during a long period. At 40 percents and after around three hours of bitbox abuse (in a very friendly and satisfying way ) it starts to flicker again. It is not so annoying, I mean it is definitely playable like this, but I just was a bit concerned, afraid that my module was frying...

    Hi again y'all. Here's my video about that 50-80% brightness setting issue. I wouldn't call it a FIX per say, just playing with the machine's settings. Such a simple/basic procedure I could have done right from the start!
    Tried many times to upload video via vBulletin... simply doesn't work... for me anyways.

    So, there's a Youtube link: https://youtu.be/MgJIHI8aOMA

    Will get to Christine's questionnaire soon, which i think is quite relevant. Aaarrgh, just don't have time!

    Good news mate. Thanks for including details of your fix.

    FIXED! ... First tried Aaron's & staticcharge's ribbon cable reseating. To no avail. Then, Home-Settings-Brightness.
    Turns out my Bitbox's screen seems to flicker between 50% and 80% brightness setting. Go figure.

    I guess I had it set between those values all along. Set it at 40%, plenty enough, this screen screams Bright n'Crisp! Had the unit on for hours at 40%, no more flickering. Ahhh!
    Thanx Aaron, Christine & staticcharge for the input! Will try n'post a video. Now let's play!

    That looks like a back light issue, have you tried my fix? Let us know if it works.

    Some people have reported trouble with uploading video to the forum. We use vBulletin software for our forum, so we have to do it the way they designed it to work. Apparently you have to upload the video to your profile first, and then you can add the video to a post. Here's a video tutorial about it:

    I hope this helps. I'm sorry it's not very intuitive.

    I would like to add that we have a series of tests that are run on each module as part of the manufacturing process. We only ship modules that have passed our testing. We will work with our test team to re-evaluate our testing procedures and ensure that every module is fully tested.

    I'm glad you fixed it. Thanks for also helping other people get their modules working. I appreciate the help.

    The fix previously documented in my post fixed my Toolbox module and after 6+ hours it didn't glitch once.
    As previously mentioned the glitching didn't effect the modules function so Aarons advice would be one to take note of. I tried reseating the larger ribbon cable first with no noticeable difference hence me doing the same with the smaller one.
    If I'm reading your manual correctly the series 1 and 2 modules both require a +12v supply and one would assume that anyone using this class of module would also be using a good standard power supply ie with an accurate 0v reference and not the Tiptop 2 pin power adaptor type. All 0v rails Need to be earthed via the mains supply earth pin, for safety if nothing else. This will ensure the 0v rail is an accurate 0v reference for the ICs to function correctly and as designed. Without the grounded 0v you would have a floating reference and therefore the behaviour of the ICs would be unpredictable.
    US 110v supplies run more stable, the EU/UK 220-240v sometimes going as high as 251v at peak times so it would be interesting for people to add where they are geographically when answering the above questions.
    For me,
    I use the meanwell RT-65B PSUs, every 3U rail in my 18U x 168 rack use one PSU with a Ripple noise rejection bus board each, all earth bonded to the 0v rails. Modules that share this bus board: Brains, Pressure points x2, Eloquencer, ER-101, Intelijel planar, A-151 and A-160.1.
    All my racks, monitors and mixer run through a Sollatek voltage conditioner, so I don't really suffer from over/under voltage.

    I'm trying to gather more information about this issue to try to help resolve it. If you are having problems with flickering, could you please answer the following questions?

    1. What power supply are you using for your rack?
    2. What other modules do you have that are hooked up to the same power supply?
    3. Which format of power is the ultimate source for your rack? This depends on which country you are in. For example, the US uses 110 Volts and 60 cycles, while Europe uses between 220 and 240 volts. (This probably won't matter because the rack power supply should even it out. But I've learned to question everything.)
    4. How old is your module?
    5. When does it happen? Right away? After it's been on for a while?
    6. Which module does it happen with? Toolbox? Bitbox?
    7. If it's series 1, what is your serial number? (For Series 2 we only have one batch so it won't matter.)
    8. Did you buy the module new or used?
    9. Where did you buy your module?

    Please answer as many questions as you feel comfortable with.

    Thanks in advance,
    Christine

    I spoke with Aaron yesterday. He agrees that it's good idea to try to make sure the ribbon cable for the screen is attached properly. Here's a video he made that demonstrates how to do so:
