TV picture wont come on after replacing power supply panel

TV picture wont come on after replacing power supply panel(it didnt power on it all, picked it up off side of road) all I get is a red light and a click sound when I press the power button then it turns off , trying to fix it myself

Update (03/08/2022)

My model is a tcp46c2, and yes and you have it correct the TV didnt power on it all, so I ordered and replaced the power supply board, now the tv has a red light followed by a click when I press the power button on the front of the tv manually

Hi @toreup34 ,

Here’s a link to the service manual that may help.

Go to p.18 to view the troubleshooting flowchart for No Power problems. Since you have replaced the power board you may have to move onto the A board next, although it may pay to check the fuses on the P board mentioned in the flowchart, in case they’ve blown due to a problem elsewhere.

Hopefully a start.
