Teenage Engineering OP-1: Why won't audio come from the right channel of my OP-1?

Tue, 17 Mar 2026 18:42:12 -0700

I have made sure that all the tracks are panned towards the center, but no audio comes from the right channel. If it is plugged into speakers or headphones and panned to the center, audio only comes from the left side. If it is panned to the right no audio come out. I was curious as to if there is something I am missing or if this is a hardware problem that requires repairs/parts. Thanks!

Teenage Engineering OP-Z: The front buttoms pcb (op-z)? Where do I find?

Thu, 27 Nov 2025 06:51:04 -0700

Hello guys, i wish you are all really well!

I have a question, after coming all the way to Brasil with my op-z looking for someone to fix it, which i found just in Berlin for now.

My Op-z is 40% fixed by now (it was problems of dirty inside, humidity, etc) and now, Tom, which fix for SchenidersLaden with his team, told me that i should find some Front Buttoms Pcb for it, to continue the fixing - ‚cause some of them are not working properly, and this bothers me while composing.

Do you guys have some of them - used or new - to sell or give it to me or know where i could find it?

This would help a lot not just my artistic carreer, but my lufe as a whole.

I keep searching from here,

Wishing again all the best for your

Kindly

Pedro Máia

Obs.: By the way, the op-z module and the cables that i got from you are working pretty well! Just the cable of charging the op-z that lost all it‘s skin, so it‘s like crude now, with the silver cables inside appearing - could it be harmful for me?

Teenage Engineering OP-1: The “4” track button is not working

Tue, 30 Sep 2025 12:20:13 -0700

Hey, so the four button on my used OP1 stopped working recently. I noticed it a few weeks ago. But, when I wiggled the button it seemed to work again. But, now it doesn’t work at all. I assume it’s a mechanical issue. Can someone tell me what I can do to fix this button myself?

Thanks,

Teenage Engineering OP-1: Why does my OP-1 keep restarting

Mon, 17 Mar 2025 03:07:16 -0700

Hey everyone, I have so many issues with my OP-1 it's driving me a bit nutty.

My first issue is the audio is only outputting a signal from the right side. I've checked the sync settings and in the mixer everything is being sent down the middle. I get a tiny output from the left side but it's very quiet and distorted. I have tried multiple cables and the OP-1's output settings too.

My second issue is that my OP-1 will often just turn itself off, go to restart, then crash. Sometimes it will turn back on and other times it won't until I reinstall the firmware. It keeps happening and won't consistently stay on for more than 30 minutes. ⏎

I really want to use my OP-1 for my live show but I can't in this state. Any advice is deeply appreciated! I've replaced the connector board recently (twice!) and the problems still persists. Thanks ⏎

teenage engineering EP–133 K.O. II: How do I figure out what part to replace if it won’t turn on?

Sat, 15 Mar 2025 14:50:26 -0700

I tried connecting my used OP-1 to my new KO II. Both powered by batteries and plugged into my Roland Microcube (battery power as well). Mistook a “phone accessory” cable for my aux cable when I linked the two devices. There was a terrible screeching sound and all the dashboard lights on the KO II lit up before going black and won’t turn back on. I know almost nothing about the insides of electronic devices. Can this be fixed (by me)?

teenage engineering EP–133 K.O. II: Another K.O. II sob story (friggin' knob)

Wed, 11 Sep 2024 16:51:30 -0700

To begin, I've already reached out to TE, and I'm awaiting a reply-- however, I figured I'd post here too, just to see if anyone else has figured out a fix.

My little machine took a bit of a tumble (oops my bad) and I broke the orange adjustment knob. I took it into my boy at my local music shop, and he gave it a good repair attempt, but it was no good. He said he thought he may be able to fix it if I could get a replacement knob component, which is easier said then done.

Like I've mentioned, I've already reached out to TE directly, but I was wondering if anyone had any hot gossip about K.O. II pieces-- any quirkly little freaky bootleggers who could give me a handy. Or whatever. Hopes are low, but Idk I'm feeling lucky, baby.

teenage engineering EP–133 K.O. II: Fader is loose, causing flickering

Thu, 22 Aug 2024 07:16:39 -0700

Hi, I recently opened up my ep-133, there is something wrong with the fader. When I use the pads to play a sequence there is flickering caused by wiggle in the fader. It appears the fader is loose or broken. I have another ep-133 unopened (I was planning on keeping it as a collectable) and I'm worried it will have the same issue as they were purchased at the same time.
