@dorosk this will be very difficult without a schematic. When I test for any short circuits (short to ground) I use the diode mode on my meter. Diode mode allows you to quickly identify voltage drop. Meter in diode mode, red to ground and black to test component.

If you know you have a faulty component like your overheated PLD, you do want to either replace it or remove from the circuit. Replace the damaged component then check your components.

Out of curiosity, let us know what it actually is that you are working on.
