I export jpegs from InDesign to be displayed on flat screen TVs for a client. On some TV models they are unable to load the jpegs and the only work around is to open them in MS Paint (I am on a Mac so boo!) and save as a jpeg again.
Can someone please advise what the problem is and how I can fix this, rather than having the client use MS Paint to fix?
My best guess is that you have exported your JPEGs in CMYK colour space and your TV does not understand it. Make sure you have chosen RGB as Colour Space in Export JPEG window.
There´s some other options too that you could try to toggle (like Format Method and Simulate overprint which may cause troubles in some special target devices)
