Heated bed fried?

Hello, so I already tested my heated bed directly on the power supply and it was OK, I tested with pronterface and it was OK, now for some reason it is not heating up again, I checked the continuity and it has none, is there anyway to ressurect it? What could have caused it?

If the bed has no continuity its broken... Since its a heater, you cant easily repair it as the repair would have to survive the repeated heating and cooling ...

Check its not just the wires... (you didn't say exactly what you tested)

Any damage to the bed could cause a weak spot that would excessively heat up and fail at that point.

One common cause is people mounting the bed on bits of metal that damage the board...

I did kind of a bad soldering job but I tested the continuity between the end of the wire and the underside of the solder and it was OK for the 2 wires, but the continuity between 1 and 2/3 by touching the metal plates did not work
