NOW FOR THE HIGH VOLTAGE SECTIONDoes your multi meter have auto Range or do you have to set it to voltages?????
If you do have to set it make sure its set to the 100v range
now put the black lead on J5 pin 1 which is ground and put the red lead on J5 pin 3 hopefully its shows between 90 -110 volts if it does it working if it doesnt the board need work
Hope this helps do be carefull when testing dont short any pins with the multi meter
