Download Blank Video

Windows 8.1, working wifi connection. Had my printer for many years now. It acts like it's printing, including slowing down on more dense areas, but the paper comes out blank when fed from both the upper and lower cassettes.
I have also run into this issue (I think). Sometimes the cell becomes non-responsive, sometimes clicking adds a random subset of the text to the cell again, and usually after that all occurs for a bit, the cell goes blank. I have learned to just stop clicking and manually copy the text to the next cell and delete the original.
So just yesterday i started sketch up to find i just have a blank screen and unable to interact with the page. The day before it was fine and i was able to see and work on my drawings. When i go to start sketch up on my integrated graphics card the drawings show up and im able to work on the drawings, although it is much slower. I have a Nvidia GeForce GTX 1050 and all drivers have been updated. Iv gone into the OpenGL and changed the settings in there and still nothing. Any clue to why this is happening? Iv also just downlaoded the 2019 version but the problem persists. I, guessing its something with my graphics card.
cheers
BTW, other tags such as Rate-limits and Settings are fine; but if I switch from them to the Usage tag and the webpage goes blank, then even if I click the backward arrow of the browser, the pages of Rate-limits or Settings will always be blank, unless I reload the webpage manually.
Received my Mk4 on Friday, and overall it has been within my expectations. I upgraded to the latest firmware 4.6.2 and besides having the intermittent "I2C receive fail" red screen of death that ncessitates a reboot, the screen sometimes goes blank after a print is completed. No amount of clicking or turning of the wheel will bring it back, so a reboot is needed. Is this a known "feature" or is it a bug?
I've had my screen go blank at various times, including during a print but the print did complete successfully. I contacted support and they asked me to check all connections and when these were confirmed to be tight, they concluded it might be a problem with the xBuddy board so they arranged an RMA for the board. I'd suggest you contact support and see what they can do to help you.
It works for a bit because when the motors aren't doing anything there's less interference, and it blanks while printing because, well, motors are moving. That would also explain why it's completely fine while turning on until the "progress bar" reaches the middle and the printer beeps... That's when the motors activate (you can even hear them or feel it by touching them)!
I have the same issue with my MK4. The LCD goes blank but the print goes all the way. I reached out to support by email and the guy recommended a few things but then stopped responding. I'll go on live chat later today.
To give you guys a little more context, in addition to the LCD going blank or changing colors or maybe just displaying parts of the picture, I have had nozzle cleaning errors, as well as errors 13202 and 13315.
I have been using Obsidian without any issues for a while now. 14 days ago on Mar 8, 2022 (in Australia) Obsidian started with a blank screen (making it unusable). I was able to resolve this by reinstalling the application. It worked then for 7 days and then on Mar 15, 2022 it again started with a blank screen but this time reinstalling it does not work.
I am running it on a Windows 10 laptop.
I was able to get it to briefly run by deleting the Obsidian folder from my $Appdata locally and roaming and then reinstalling the app. It then ran for a few minutes but then failed, first losing connection to plugins and then after restart was back to a blank screen.
Attached is an error trace from the command prompt. My companies IS support checked for sync issues and said that for some reason the computer is switching to running offline.

The truest test of the value of any text-handling program is, can you do basic, typical tasks quickly, easily, and in an intuitive way. Having to read a manual and create an elaborate style sheet to write a grocery list is a FAIL, and so is having no way to select items and have the program understand that a list is text, NOT blank lines.
After posting that last reply I clicked on the Launch-icon in the Software Manager and low and behold, the blank screen turned into the normal working Joplin.
So it is solved now, but what may have caused this behavior I don't know

Blank is a placeholder for "no value" or "unknown value." For example, a Combo box control's Selected property is blank if the user hasn't made a selection. Many data sources can store and return NULL values, which are represented in Power Apps as blank.
Any property or calculated value in Power Apps can be blank. For example, a Boolean value normally has one of two values: true or false. But in addition to these two, it can also be blank indicating that the state is not known. This is similar to Microsoft Excel, where a worksheet cell starts out as blank with no contents but can hold the values TRUE or FALSE (among others). At any time, the contents of the cell can again be cleared, returning it to a blank state.
Empty string refers to a string that contains no characters. The Len function returns zero for such a string and it can be written in a formulas as two double quotes with nothing in between "". Some controls and data sources use an empty string to indicate a "no value" condition. To simplify app creation, the IsBlank and Coalesce functions test for both blank values or empty strings.
We are in a period of transition. Until now, blank has also been used to report errors, making it impossible to differentiate a valid "no value" from an error. For this reason, at this time, storing blank values is supported only for local collections. You can store blank values in other data sources if you turn on the Formula-level error management experimental feature under Settings > Upcoming features > Experimental. We are actively working to finish this feature and complete the proper separation of blank values from errors.
The IsBlank function tests for a blank value or an empty string. The test includes empty strings to ease app creation since some data sources and controls use an empty string when there is no value present. To test specifically for a blank value use if( Value = Blank(), ... instead of IsBlank. The IsBlank function considers empty tables as not blank, and IsEmpty should be used to test a table.
When enabling error handling for existing apps, consider replacing IsBlank with IsBlankOrError to preserve existing app behavior. Prior to the addition of error handling, a blank value was used to represent both null values from databases and error values. Error handling separates these two interpretations of blank which could change the behavior of existing apps that continue to use IsBlank.
The Coalesce function evaluates its arguments in order and returns the first value that isn't blank or an empty string. Use this function to replace a blank value or empty string with a different value but leave non-blank and non-empty string values unchanged. If all the arguments are blank or empty strings then the function returns blank, making Coalesce a good way to convert empty strings to blank values.
Coalesce( value1, value2 ) is the more concise equivalent of If( Not IsBlank( value1 ), value1, Not IsBlank( value2 ), value2 ) and doesn't require value1 and value2 to be evaluated twice. The If function returns blank if there is no "else" formula as is the case here.
At this time, the following example only works for local collections. You can store blank values in other data sources if you turn on the Formula-level error management experimental feature under Settings > Upcoming features > Experimental. We are actively working to finish this feature and complete the separation of blank values from errors.
By default, the Text property of a text-input control is set to "Text input". Because the property contains a value, it isn't blank, and the label doesn't display any message.
In eventual supporting browsers, the :blank pseudo-class will enable developers to highlight in some way input controls that are not required, but still have no content filled in, perhaps as a reminder to users.
