Prepare yourselves for a downward spiral into depression with this thrilling story.
If anyone browses this subreddit often, I previously had the problem of my keys retriggering when pressed on a used OP-1, so it would play a drum hit twice is a quick succession and skip octaves. Here is that post if you also want to read that.
After noticing that the keyboard replacement part was on sale, I decided it would be a good idea to open it up and re-seat the connector wire to the keyboard, just to check if that was the problem before spending £80 on a new keyboard part. I used this guide: here.
Ohh it went downhill from there. After putting it back together and making sure that everything was seated properly, nothing seemed out of the ordinary at all, the worst thing I thought that could happen was that the keyboard retriggering problem would remain (and it did, of course).
I booted it up aand a white flash came up and covered the entire screen for a split second before turning completely black. The unit still made sounds from the keyboard and it was still recognized by my computer when plugged in. "Well, shit. It can't get any worse than this."
Some keys didn't work so I opened it back up and made sure that the keyboard connector was in snug. I turned it on again to make sure, and finally, all of the keys were working, but the screen still wasn't. This only happened twice, but the screen would come on perfectly fine except for the fact that all black parts of the screen were white. I managed to record it by accident and I thought I was finally getting somewhere (I wasn't). Here's the video of it happening.
Then after turning it on and off hoping that it would fix itself, it got worse. Now it isn't even booting into the OS, it isn't making any more sounds and it isn't even taking a charge or getting picked up by my computer anymore. It's completely dead - except it still flashes red for a split second (almost) every time I boot it up and the speaker clicks whenever plugged in via USB or turned on. This is where I'm at now.
I'm currently going through Teenage Engineering's support page on what to do with no success so far and I've tried looking for people with similar problems with no success.
I don't know what caused this, all I did was disconnect and then reconnect the keyboard? I really hope I haven't got an expensive paperweight. I've already spent a couple of hours crying over this before coming here. I have no idea what to do other than to keep trying the steps on the TE support page, selling it for parts or repair or sending it over to TE to look at and end up spending probably £400 overall getting it fully repaired.
**TL;DR Used OP-1 (I've had it for over 2 months) is completely dead after reconnecting the keyboard - it only flashes a white/red on the screen and the speaker pops and after that, nothing. No sound, no charge, nada. It's currently charging whilst off.
