T-Con pcb did not fix this problem. I still have this problem and now no image at all.
@bwebs blue tinted screen are usually not the result of a failed T-con board. It is usually related to bad backlight LED’s. You changed the T-con board and now nothing the set is dead or do you have works any sound. Give us more details about your TV. Things like what it does still do are important. Make and model are a must and more history is helpful.
