The battery charged and some keys were working, nothing came up on the screen it definitely needs repair but I do feel it is repairable. I don’t have the full box only the slip cover. It was strange the usb chord was sealed and unopened?”

” Works well for about five days, but then refuses to turn on. You have to connect it to a computer, reinstall the firmware (wiping everything you’ve saved), and it will start up fine for about another five days. (Instructions for how to reinstall firmware are on Teenage Engineering’s website, see screen cap for google search.)

As far as troubleshooting, a previous owner replaced the connector board, battery, and flex cable, but still no luck. I’ve also tried doing a factory reset and formatting the internal drive, but still no change. I suspect that the issue might be the DSP board, but those aren’t easily available.

Anyway, it works while it works, making this an inexpensive way to get an otherwise fully functional OP-1. See pics for cosmetic bumps and scrapes (the corner, several scratches on the screen). Comes with cable. No case, but will be well packed. No reserve. Have fun.” Click here to visit listing on eBay

“Teenage Engineering OP-1 Synthesizer barely used with small defect.

” Teenage Engineering OP-1 Portable Synthesizer. Listed as Model Number TE002 on the back. This appears to have been barely used with just a few faint scratches on the back, but otherwise it looks new. It powers up just fine and seems to work as it should. With that said, I am not an expert at all on these so if you have any questions, please let me know. We guarantee that this is fully operational, and if you are not happy with it after receiving it then it can be returned for a full refund (as long as it is returned in the same condition). Many extras are included with this – dark green padded carrying case with strap by MeMe, Kong Monotron Analogue Ribbon Synthesizer, original USB power cord for OP-1, hard plastic cover from Decksaver, 32GB flash drive and two connectors/convertors (not sure exactly what these are but they are pictured, one is from Radio Shack and the other says Ooze).” Click here to visit listing on eBay
