I have started getting colour patches on my tv screen. they are a pale blue . The first one was low down to the right. About four square inches. The second appeared a few months later on the left and slightly smaller. The third is about six or seven square inches and is left of center and a third of the way up the screen. I can still see the screen quite well but I am wondering what is going wrong and should I start saving my pennies for a new TV. BTW it is a Samsung UE40H5500 Ta! Mike
@willcallhimfred could be an issue with the main board (most likely) or the t-con board (unlikely) as well as wiring issue (loose or frayed connectors and cables). Of course the big one here is a bad panel. Unplug your set and remove the back. Check all of your boards for obviously damaged components like domed looking or leaking caps. (Samsung has a real issue with that). You can always post some good images of your boards with your question so that we can see what you see. Use this guide Adding images to an existing question for that.
