DUET 0.6 heat bed power not working

I am using DUET 0.6 from Reprap ltd. Using 12V power supply. Recently due to some of my mistake, one of the board burnt (minor). Then I replaced with another DUET 0.6 board.

In that it was having issues with heating the heat bed. The soldering of the screw terminal was loose and one side soldering was totally removed. So, replaced with another screw terminal on the reverse side (Which was having good soldering contact. Image attached). After that bed was heating and printed successfully 2-3 prints.

One week later, now again the heat bed is not working. When giving the temperature, the terminals are not showing any Voltage. I checked for the tightness of the screws. Everything is ok. What will be the issues?

Thanks

Yeah. Checked in DUET3D. Thanks for your kind support.

If you want to keep going with that board I would get an external mosfet with more power capacity.
Once it starts to fry its likely to be susceptible to burning again and take the whole board with it....
