Ninja DCT401 Double oven/air fryer Possible microprocessor issue?

[tbsmith]

I'm having a random issue with this otherwise nice double oven/air fryer. It sometimes does not respond to the controls. Sometimes only the upper control buttons work, sometimes they all work and sometimes none of them work. The power supply is good as the control board has a steady 5V and 3.3V. The pushbutton switches are all good as tested with multimeter. When the buttons are working, there is about 2.5V to the high side of the pushbutton. I'm assuming pressing a button grounds the input pin to the microprocessor. When the buttons are not working, there is about 0.3 volts on the high side....

I am attempting to test a samsung power supply board to verify the pfc ic is working. I am powering up the board with my isolation transformer. The board turns on fine but when I attempt to connect the ground for the scope probe, it trips out the isolator. I was taught not to 'float my scope' so I am wondering if I should test without connecting the ground lead or would that be asking for trouble? Not sure how else to test, I don't have a portable scope. I could plug direct to mains power but that would bypass the safety factor.

At the risk of sounding like a total noob I'm asking If anyone can help me locate the "Desktop" folder on Windows 11. I am trying to make a backup of all the user data from an SSD (mounted externally) that has Windows 11 installed. I was able to do this before up to Windows 10 by navigating to the User folder --> Username and there I would see the individual folders, Documents, Downloads etc. Attached is a screenshot of the folders I do see within the Users / Username folder. Any help locating the desktop folder will be greatly appreciated. Thanks in advance to the community. ...

Originally the tv arrived with dimmed backlights (not failed leds) but everything else worked ok. Adjusting backlight in menu did nothing but voltage changed on dimming control pins,
0% p_dim at 1.65v and a_dim at 1v
50% p_dim at 3.3v and a_dim at 1.65v
100% p_dim at 3.3v and a_dim at 2.88v

Changed backlight leds anyway as always like to have complete peace of mind they wont fail shortly after selling the tv. No change as expected!

Leds are 2 rows of 15 6v leds.

Hi all,

It's gonna be a long intro, so please buckle in, as it's a problem that's been bugging me for several days now. Thanks in advance.

So, I have 2 modems/routers, whatever the proper nomenclature is, one from ISP and one mine. I want to power them via USB-C rather then their original mains adapters (for reasons, that are hard to explain to sane people). Both routers come with 12V/3A mains adapters.
For this purpose I acquired USB-C charger with 250W and 5 ports, 2 of which can supply max 20V/3A. Since 12V isn't a standard PD voltage option (and to future proof,...
