My Voyage VR-9000 has an issue with 2 of the frequency display numbers not lighting all segments when cold but when warm it works correctly but the same segments are dimmer than the rest. I am thinking of replacing all of the display but I have never done this before and was wondering if I should pay the shop or do it myself. I don't want to destroy my radio although I can solder very well and have all the tools. I haven't seen much online info on this either. Thanks.
