Quoted from FatPanda:
replacing board components isn't bad if you have the proper tools (desoldering gun IS A MUST). Especially if it's just bad SCRs. Some boards are too far gone (ones that have bad battery damage) where a replacement board would seem more fitting. Like I said, I'm the ultimate cheapy
I’ve done the resistors, piggy backs and the full board replacement. Since I’m not having to buy these left and right (once a year maybe), I just replace the board and be done with it. Just under $100 for piece of mind. Well worth it.
By the way, I have a stack of semi working to working lamp boards from various early stern and Bally games for sale if anyone wants them. Haha
