I have been using LR5 for quite some time and never had any issues with camera profiles for all 3 of my cameras. For some reason this week the profiles disappeared. All the pictures in LR have a yellow tint and when I view them on my PC they are fine and PS is fine too. I tried to move the profiles manually into my user folder for my specific cameras and it didn't make any difference. No updates are available as per the help prompt. I uninstalled and reinstalled the program just in case something got corrupted for some odd reason and no changes. I downloaded the DNG converter and the files are still all yellow in LR. Anyone has any suggestions on what else I can do? Thanks in advance.
Profiles disappearing is usually that your current image is not a raw image since profiles are only for raw files.
A color-cast for images (and the histogram) in LR is usually because your monitor profile is incompatible with LR. Usually this incompatible profile is supplied by your monitor manufacturer. You can if this is the problem by setting your profile to sRGB:
