Hi Mario,
One must carefully "pull" (lift) the upper board from the component side--upwards--Use two hands -- your left one to lift the PCB, on the left side, first --just a little-- then "work your way" across that plug--the plug, is all that's holding it--Be sure to rest that removed board, on the safety mat-- look for a poor solder joint on that failing SCR, or near it-- --Ron Rich
