hiya!

I got a cheap LED strip with PSU, controller, and IR remote. I didn't look at it too much, figured it would be easy to stick it under my kitchen cabinets.

however, this thing blinks and fades and whatnot and I'm supposed to switch it over to constant light by repeatedly pressing the remote, which a) works shitty and also b) don't wanna do that. I just want to plug it into power and it lights up and that's the end of our interaction.

so, I opened up the PSU/controller and I'd like to locate the spots that give me +12V and GND and I can bypass the whole blinky fadey mess.

it's a single-sided PCB. the top three wires on the right are for the IR receiver, ignore 'em. the bottom 4 are R, G, B, 12 V, respectively. I'm shorting RGB as it's a white-only strip.

can you hazard a guess where I'm most likely to succeed?

Thanks for the closure, glad you got it sorted! You might just need to change the batteries on your multimeter to get it back to normal.

sure, thanks for helping out. got now a cheap hack for lighting my abode, commercial solutions are like 6-8x the price. the CRI is crap but it's better than nothing.
