hi
i have a spy hunter project in unknown condition very dusty like it had'ent been on or touched in 20 years and need some advice.
what i have done to the game before powering it on.
rebuilt the monitor g07cbo verified it working with a different game.
looked over the power supply changed some caps. re-flowed the entire solder side.
changed all the caps on the other little boards sound/cheap squeak/steering censer,ect and re-flowed all the header pins on all the little boards.
adjusted the +5/+12 voltage before plugging in the 3 board stack but had all the other boards hooked up and it was making a loud humming noise in the speakers that never quit it this normal with no board stack hooked up?
then hooked up the main PCB.
turned it on i had vertical scrolling lines on the monitor witch i think was just out of adjustment. the same loud hummmm as before. then before i could do any adjustments i saw smoke coming from the super sound PCB on the top of the 3 board stack and it had fried the black resistor/filter looking thing # cp204. i quickly unplugged it to not do any further damage to any thing else hopefully.
so what could be wrong or did i mess something else up during the re-flow of the headers or is something already wrong and needs to be fixed.
i have 3-4 other spy hunter pcb stacks all in unknown condition but don't want to plug them in and have them get fried as well.
so what should i do now what should i look for or should i try a different PCB stack or just change out the super sound board and try again.
Peace
