What should I check next? Not sure this one is very small 2 pins on top 3 on bottom and the voltage was changing on the top 2 pins.

F1, F3, 7805cdt2, and may be F2 and F4 some where else on the board. Continuity tests good across them. I’m not sure what the easiest way to list this is. I would love for the power supply to be bad since that seems an easier fix than 7805dd2t main board. Then test the connectors for voltage again. Hello Stealth71, Pin 1 of the IC often has a circle next to it like in the picture attached.

Let me know if this means anything. Location – Labeling Top row pins Bottom datassheet pins Datasheets are guesses.

Thank you for the help. Woke up the other morning and the light was flashing this pattern and just repeats forever. Should I start checking the voltage regulators? I only see U24 3-pin.
