I have a Phillips 26PFL4507/F7. It wouldn’t come on so I replaced the power supply board and it still won’t come on. What do I do next?

I had the same problem of tv won’t turn on model Phillips after getting unplugged or power knocked off by a storm unplugging it alone did not work solution unplug it hold the power button down 15 seconds release plug in back in powers on every time
