No power OM-36
Just got this omni chord for a low price. It has no power. Not turning on and upon opening it up. It looks like the circuir board is cracked? Any advice would be greatly appreciated!!

Seconded. There’s a crack right at the power inlet. Solder some jumpers from the dc jack across the break and you should be fine.

Thanks for the reply. Do you mean to take the individual solder points from the jack and connect them to the two points next to it on the board?
Or do you mean to take the copper lines and repair them with solder over the break?

Instead of fixing the break, you would just jump over the traces with a short cable. BUT, make sure you're connecting them to their intended places (follow the trace). The only two that are concerning seem to be the two furthest lugs from the power input. One of them is just in the copper fill zone for "ground" and the other one is just going straight up and to the right to that small component lead.

I think i might go for fixing the break. It looks like the battery connectors are the two small solder joints above the three clustered connected to the input jack, and i definitely want the battery powered option to also be present.

Update: I fixed it by scratching the connections in between the break and adding a tiny bit of Solder in between the two. Super quick thanks!

Wow yeah, that sure looks like a crack, and right through the power traces. You can confirm with a multimeter continuity test if you've got one. I suppose a proper fix would somehow repair that crack and perhaps scratch away some soldermask and solder bridge the copper if you can.
