I have a Sceptre 55 inch tv. Tv turns on for spit second and then no screen or sound. Done some research and replaced the power supply, my tv isn’t working still. What else could it be?

Some other board in the TV is drawing more power or isn't functioning at all. Use a voltmeter to be positive the power supply board is sending the correct voltages to the other boards.
