Hi guys,
Just dug out my old DR-550 to give a few bends a go, but unfortunately it seems the output is a bit buggered.
Neither of the large output jacks give any signal and the sound from the headphone jack is only working on one channel, at a very low volume and with a lot of constant noise.
I cracked it opened and cleaned all jacks with contact cleaner, cleaned inside the volume pot and checked all of the components and solder joints. Couldn't find a problem and the cleaning didn't help at all.
Has anyone got any idea what I can try next or any experience with the same issue?
Any help is very much appreciated!
