Hi, first time poster so hope this is correct place.... Really hope someone can help please! Trying to fix Panasonic DMR-EX768EB for wife's nan which is only showing black and white now?! It was colour previously. I have checked all cables and been through every option I can think of... One of the old recordings was showing colour but everything since and TV guide etc is black and white?! Set up is below if it helps? I've seen this asked on other posts TV HDD box ----- ----------- Scart (ext rgb) -----> AV1 (TV) HDMI (HDMI in) ----> HDMI out Ariel (rf in) ----------> Wall socket Ariel (ant in) --------> RF out I've also tried pressing green button few times quickly that was mentioned on another post. Really hope someone can help, much appreciated!!!
