Hello good people, I have just made a stupid mistake and I connected my CMB24D to a 240v supply instead of the 12v, does this mean the board is now completely dead ? or can it be repaired ? thanks

How about the main fuses? Did they blow? If so you may have lucked out.

Oops!!!

Off hand, it's likely dead.  As JR suggested, you can try replacing the fuses, and it is possible that they protected the board, but I would not count on that.

As long as there is not major damage to the PC board, it is repairable, but may not be practical.  With that much over-voltage and reverse polarity, there could be a lot of devices blown.

Good luck!

Ouch!

Like others, I hold little hope that the fuses saved you. Solid state devices, capacitors are going to be stressed so far beyond any over design limits in an instant.

I assume, you got confused with the input configuration for the CTB16 (AC controller). which can run on 240V mains

Get out the butter and jam, because that thing is toast.

That's actually a bad thing.  If the fuses had blown fast enough, they MAY have protected the board (large emphasis on MAY).  That the fuses did not blow most likely means that something on the board burned up before the fuses could blow.

Sorry.

I gotta know, was there a lot of smoke?  :huh:

Or a Bang?

Or a pop, sizzle or something.

Using 240V instead of 12V is brutal.  Along with the smell of electronic smoke I'm getting a secondary aroma of brain fart.

there was no smoke and no bang, red led flashed once and that was it.

 

WOW, if you were going to lose a $100 controller you should have at least got something out of it.  :D

If the fuses survived the board did not!

Let me add, the small individual circuits could have survived, in my original post I was speaking of the 2 large white fuses right next to the power terminals. If they are toast you have a chance
