Picked this 25 Ltd classic up a couple weeks ago, already found out that the channel display has a few segments out and that the meter light is out. The bright/dim switch also doesn’t seem to work so I thought I’d open it up to see if someone had been inside and maybe wired something extra in. Does anyone see anything out of the ordinary in here? The blue wire on top of the board definitely looks out of place. Just trying to figure out what I have here. The blue wire seems to connect r-81 wit to-6, what would that accomplish?
