A flashing green light on a Swann 960H Pro Series security camera system can indicate a few different things, depending on the specific model and configuration of your system. Some possible causes of a flashing green light include:

1. The camera is in setup mode: When a camera is first powered on, it may flash a green light to indicate that it is in setup mode and ready to be configured.
2. The camera is in standby mode: When the camera is not actively recording, it may flash a green light to indicate that it is in standby mode and ready to start recording.
3. The camera is recording: Some models of the Swann 960H Pro Series security camera system have a green light that flashes when the camera is recording.
4. The camera is low on power: Some models of the Swann 960H Pro Series security camera system have a green light that flashes when the camera is low on power.
5. The camera is malfunctioning : Some models of the Swann 960H Pro Series security camera system have a green light that flashes when the camera is malfunctioning.

There are 2 different systems I know of for the light shut off because of excessive door open time. One system uses a heat sensor near the light bulb to shut off the light if it gets too hot there. To turn light back on that sensor needs to cool back down after door is closed. Second system for the light off---is that the time light on is actually timed by a electronic part on the mother board. It would come back on until the mother board senses the door closed for a similar amount of time. sometimes just closing and reopening the door will bring it back on, All depends on the type light system.

Check the wires to and from the sensor there is a bad wire somewhere. Good luck

The green light just show that the motherboard is getting power.
The power button of the front of the case is connected to the mother board, not to the power supply, usually in the extreme lower left corner along with the with the HDD and Reset Button cords; Power button wire are labeled and usually red/black.
If all wired correctly, possible bad or stuck power button or reset button.
Hope this helps.

i would say try swapping your motherboard for another one to test and see if your motherboard is bad if that doesnt work take it to a computer repair store

It sounds like a logic board problem to me. I would remove the board and look for bad connections especially around that small transformer.

If the lights in the door sensors do not light you have either a bad logic board or bad wiring to the sensors. Replacing the logic board is usually the cure.

Check the lid cover. At the edge, there is a plastic housing some sort of a magnet. This is the magnetic sensor for lid cover open protection.
If the magnet is not there, place a magnet at the position on the washer where the housing will come in contact with the washer when lid is close.

Can you bypass the switch
