Has anyone elses 48 in 1 board taken a crap on them? Some of the lights on the board still light up, but I hooked up another PCB and it works fine, so there must be something wrong with the board. Wondering if this is a unique case or not.
 
Yeah, it happens unfortunately. you could try cranking up the 5 volts to like 5.4/5.5 but MAKE SURE YOU TURN IT BACK DOWN if it doesent work and or if you put another board in. High 5v is my last resort before i give up on a board. Prob with the 48/1 is that theyre so cheap that having one repqired would not be worth the cost bieng a new one is $75-85
 
Actually, I would ask the opposite. It's more likely that the board died because either the PS was set too high, or you got a surge on the line and had no surge protector on your setup. These boards don't like a voltage higher than +5.2....
 
This happened to me today

My 48 died, no lights at all, last week it was intermittant, then this

I did have a filter fitted, and that died too, so what came first?
 
Those boards are pretty bad about having poor soldering on all those surface mount chips under the plastic cover. If you are good a reflowing SMT ICs then give it a shot.

Also check to see if any of the small SMT chips have cracks on top of them or are getting roasty hot. Maybe you had a cab problem and one of the chips buffering inputs from the controls got zapped. If that happened then the data bus could be held in a state to where the CPU can't run.

Well, I did have itplugged into a surge protector, so I don't think thats it. I've had the thing hooked up to the same cab for over 2 years now, so besides a surge I don't think the voltage has changed. Who knows? I was just curious more so if anyone else has had theirs crap on them, maybe they have a short life span? Either way, yeah they are alot cheaper now than when I bought it, so I'll probably just get a new one, or a 60 in 1 now actually.
 
Let me know what you plan on doing with the old board. I'd like to take a crack at it and see what failed.
