Help S4 Stopped working

[theaceofspaids]

I have an S4 that stopped working.

It starts up like normal, but then has temp 0, hash 0.

The IP address that shows up on the screen, is not accessible.

I cannot ping it or connect to it in any way.

The router does not show that the device is even connected.

All the network lights indicate that it is connected.

I have tried multiple versions of the SD card images, and they all function the same way.

All cables and lights seem normal, other than the lights next to the LCD screen. The green light
comes on and stays on till the status shows up, then it is dark.

The factory reset does absolutely nothing.

Any suggestions?

maybe you need check LAN board, usually if still normal only LAN or changed your LAN cable.

I have tried connecting it to different routers, and used different cables (all of which tested perfect with a cable tester)

In all instances, it appears to have successfully obtained a dhcp ip address.

In all instances, no connection can be established.
