Question about Televison & Video
Hello, I have a Samsung tv and it had a black screen with just sound. Just replaced a T-con board and I powered it up. The display showed "Smart Tv" on the screen for a few seconds and then everything went blank like before. I tried removing the power and powering it up again but display does not show "smart TVs" like before. Could this be a bad display or fault T-con board.

The model would have helped but it sounds like you have bad LED back lights, generally a bad timing board will give a scrambled picture or a blue screen if defective. The lamps are drawing to much current and the safety circuitry in the power supply is shutting off the supplies to the backlights

Testimonial: "It is UN65JU670DF. Does that mean the LED burned the new T-Con I just replaced. Any suggestions how to check the LEDs."
