I recently posted about installing a mute button for my V1. I finally got around to doing it and immediately ran into a huge problem. When i connect everything, the button just doesn't work. To make it work, I have to hold the wire on the Valentine One in. Now i've tried about everything. I took the unit off and inspected the connections, which all look solid. Nothing is loose, i changed out the wire, i changed out the mute button (luckily i bought two). I would changed out the direct power adapter, but i dont have another. Anyway the problem is at the V1 connection. I ran into the same problem awhile back when i put a remote display in. I had to hold the wire in and down for it to work. As soon as i let go, it wouldn't show anything. I really don't want to send my unit it! Does anyone have any suggestions?
