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-1: Why is my OP-1 not turning on?

Sun, 28 Feb 2021 14:11:54 -0700

I have been storing my OP-1 and using it since 2013. The other week it stopped turning on; currently, when I flip the power switch, I hear the power get to the speaker but the screen does not glow at all. Is this a screen issue, ui issue, or is it something else? It has turned on previously but it only works after I perform a firmware update or sparingly at any other time.

Teenage Engineering OP-1: Why is my USB port not working?

Mon, 19 Dec 2022 13:49:49 -0700

The USB-port (data connection!) is not working (whereas charging via USB is).

I got to know this, when I wanted to save my work and I could not. I tried different PCs with different OS (win xp, win 10, linux ) but the PCs did not recognize my USB device OP-1. Either (most of the time) the PC did not react at all or it showed the message "The last connected USB device could not be recognized.".

Okay, then I did something crazy: I tried all of the five options in the TE boot screen.

Most of the options worked, unfortunately option 8. "Format Drive" too.

After that my OP-1 did not work at all. I can switch the device on and off, but that's all, no button is operating. The device is still charging. Invoking the TE boot screen is possible and choosing the options as well, but because of the defective USB port nothing more is possible. BTW I tried several USB cables and several PCs.

Please give me some advice. Is there a TE service point, to which I can send my device in?

Thank you!

Teenage Engineering OP-1: Why is my volume knob stuck at one volume?

Wed, 24 Aug 2016 05:27:39 -0700

Hey there,

My OP-1 Just stays at one volume. The knob that controls the volume stays at the loudest even if I turn it all the way down. Not totally sure what to do, or how to repair.

Thanks

Teenage Engineering OP-1: Why won't it turn on?

Fri, 21 Apr 2023 17:20:33 -0700

I've read every blog as well as watched the very, very few videos with regards to this problem and yet the outcome is still the same....upset individual.

when you hold down the help key you can check the battery level indicated by the VU/battery meter located on the right side of your OP-1.the battery level is indicated by the LED array on the right side of your OP-1.all LEDs lit (including the red) indicates a fully charged battery good for around 16 hours of heavy use. The stand-by time is approximately 2 years.to recalibrate the battery meter please do the following: disconnect USB, turn your unit on and leave it on until it turns off by itself. do not manually turn off the unit. this could take up to 18 hours. the unit is off when the screen has turned black.after this, charge it fully using a computer or any standard USB charger. this can take about 2.5 - 6 hours depending on your situation. (the battery is 1800mA). this should recalibrate the battery indicator.

2nd type of instruction

Make sure the OP-1 is turned off.

Disconnect the USB cable and wait a few seconds. Important!

Connect OP-1 to a computer or charger using USB and leave it turned off for a few hours.

After this disconnect USB again and leave it turned off for about three seconds.

Finally reconnect the unit again. Does it charge now?

Try this a few times, and report back.

Nope, not even the above instructions worked. Never has it ever left the studio nor handled by anyone other than me. Please HELP ME Please.

Teenage Engineering OP-1: Why won't the screen turn on even though everything else works well?

Mon, 02 Dec 2019 16:29:32 -0700

New unit, purchased about four weeks ago.

About two weeks ago the screen stopped working. The rest of the unit seems to be working well, sounds come out of the unit when I press keys, and I can toggle through different functions, however I’m working blind.

I tried to do a reset (COM while turning on + pressing 7 after ) however this didn’t work.

I tried to connect to my computer to then upload firmware, but unfortunately when I connect the unit (after turning on with COM + pressing 1 after) it doesn’t show up as a drive in my MAC. I’m not sure if this is a cable issue, as I’m using the one provided by TE.

The unit is still under warranty, but given that TE just announced they will discontinue, returning it would mean I will not be getting one back. Any help would be deeply appreciated!

The '''OP-1 Connector Board''' is available through iFixit shops internationally, but not in the US.

Would it be possible to order this part from a different iFixit shop if I paid the import fees?

Thanks!

I am wondering if I can purchase a replacement case/housing for the OP-1, the previous owner removed the connector board panel on the back with a screw driver and scratched it all up and I would like to replace it so that it is in "new" condition again. I did not see that part listed as an option.
