Do you have a jumper wire from the 12V + going into the COM terminal on the relay connector? The relay is isolated from the power to the board, so you have to have a jumper from 12+ to the COM terminal, then NO will be "hot" when the LED is on, aka caling for heat

Uhhh I dont really understand what you mean coz, I solder like my Velleman for heated bed so 12V+ from power supply connect directly to COM terminal. But i just try jumper wire 12V+ terminal to COM terminal but still nothing. I suspect that the relay is death.

No clicking sound when the light on. Try my heated bed Velleman and yes it has a clicking sound but not on the Hotend Velleman
