Found it! A-16998 - 16 Opto board

[Dave Bishop]

Managed to fry a chip on the 16 Opto board.
Anyone got a board for sale.. also if @Pick Holder or @myPinballs could tell me what could cause this chip to blow so I don’t fry another one

Would appreciate it

Thanks

Replaced many of chips on these boards. As Tom Jones says - its not unusual.

I would socket it and replace it.

Thanks Phil
Is there anything that could have blown it? Been doing a lot of fiddling with other switches and trying to undo bodge jobs on it..

I don’t have any of the chips to hand… but do have a 10 Opto board with these on.. could I try and use one of those

Not really mate, I would be also checking the diodes and all the resistors as well whilst it is out.
Just grab some chips and sockets, if you are short of money then I will give you 10 of these boards for BBB

The back of the board looks like this . Looks like the trace to that chip has risen..

Do you have a 16opto board @Pick Holder that I can buy?

Hi Dave
I have a couple in my spares,
First is a standard board used working condition £40 posted.

Second one is a standard board used fully working but has been upgraded with socketed chips, in great condition.
£60 posted.

Let me know if you are intrested in either board.
