I have sony Bravia KDL 40EX523. Symptoms in my TV include yellow or blue tint appearing in screen and temporary image persistence and everything becomes normal after an hour of continuous running and no problems how much ever time i run. But if I power down the same problem comes again and resolves after an hour. I replaced the tcon board ,even then the above said problem persists.below are aome images. Kindly give your suggestions.
