well i have another pcb,ive replaced 3/4 of the caps with 500v silver mica,to my supprise my original oled works,glad over that as its a replacement bigger 1.2" unit i fitted to the blownup atu,the old pcb with the blown cap seems dead tho,i have not tried to read the pic yet,guess the chain of events most likley was a high missmatch caused the cap to blow then rf killed the 7805 that shot 12v into the pic and scrambled its contents or killed it.
