dbx driveprack pa plus (blank display)
so I my driveack about 6 years old, only repair once due damage xlr output. Since about a years now giving some display problem normal I would remove the pcb board and apply some heat with heat gun and after a day it would come back to life. so currently no display neither any lights on the led, I figure it a problem with one of the chip on the board. input would be great also plan to bring it to technician ....

Re: 878d H-E Error
nd have to replace the original triac BTA12-600B because the diode voltage drop was a bit low when I testing it in the board and when I was removing it from the board one of the pin got damaged so I replace it with this BTB25-600B from the electronic store which think the difference the ampere rating , and am also getting 110v on the lead wire that goes to the handle some and thinking its a problem with heat sensor thermocouple circuit
but wats the best way to test the opto-coupler think I may hav to use a oscilloscope
