Head unit

By any chance does anyone near Bacup lancs have a spare head unit I can try having read one of the articles here I thought I’d try and get the radio working as I pulled it out it came on then went off then came on the article I read said about a loose wire at the back however my problem seemed to be the actual facscia of the unit coming away from the metal body it worked as I held it in place but now doesn’t want to come back on and there is no obvious on off button so don’t think I caught that just need to try a unit see if it is that or if it is indeed the wiring thanks for reading
