Yesterday I accidentally left my MVS on over night. It was still running when I checked it but it crashed as soon as I touched the cart. I reset the board but now I am getting a watchdog error. Attached is a video. Anyone have any ideas on where to start looking?

I take it the TV can't display the garbage on-screen from the Neo's early boot process? Also those clicks are really slow and intermittent.

Start with the easiest step, swap out the UniBIOS 4.0 for something else, another UniBIOS or a stock MVS System ROM.

Wow, that sucks. It's got to be something really minor. These boards are old, but leaving them on all night shouldn't hurt anything.

I would gently re-seat the bios to start.

What do you have your board plugged into?
Do you have any other PCB to test?
