My screen has died on my UK RNS-E. It looks like it is either the CCFL backlight or the backlight inverter. Rather than mess around and waste money trying to fix it I am considering just buying the better and more modern 193 RNS-E. My question is, are the newer 193's a straight swap for the older models? If so would it just be a matter of swapping the faceplates or is there anything more to it. I would like to keep SDS so presumably I need 193C or 193H. Coding is not a problem as I have Vag-Com.
