Hello everybody. Some years ago, I fried a component of a MD2 board.
It is one of those immediatly next to the AV out; it was signed "222" and it had 3 pins.
Any of you know what's that?
I got another working MD2. I de-soldered the same component (it's in a different package, this MD2 was produced later, 93). I tested it with my ohm-meter. I get 0 ohms on the outer pins, no reading with other combinations.
I don't think it's a transistor or any sort of digital pot. This might not be helpful, but you might check out this page:

I'll crack open my Genesis later on and see if I can suss out the part.
Is it marked EMx (ie. EM1,EM2) on the PCB silkscreening? That's an EMI filter.
Yes, I forgot to mention it: its "name" is EM3.
EMI filter mh
any idea where to get one of those?
It's not important, just use bit of wire.
Should I short circuit outer pins or whatever?
Yes, the two with no resistance between them.
it wasn't working; I resolved.....desoldering all useful (or maybe not) parts and trashing the PCB.
I got another perfectly working MD2, who needs the other one ??? ;D
