i have this problem with my PCB
the LCD is not turning on, but i do hear the Relay turning on and off every second. (relay is the black box at center right from that screenshot i gave you, its the one that glued with blue capacitor)
i desoldered the relay, and i checked it under 18 volts, and it does works fine.
so for me, it looks like im not getting stable DC voltage out of some components to replay.
thats what i wanted to know.. what components can cause the problem like i said earlier; turning on and off every second, not getting stable DC voltage to turn on the replay.
Capacitor? or maybe a diode? if its capacitor, then what kind?
cuz its sandwitch pcb board, i cant use the leads to find the problem
