My Panasonic tv, model tc-p46c2, turns on but turns off after 3 seconds. Started 2 days ago. Working fine before this happened. I have tried the fixes mentioned e.g holding the power and volume buttons down on tv and unplugging tv for a while then holding down power/volume buttons down while plugging tv in again. None of this worked.

since you already tried to reset and have no post error blinking you will need to go ahead and remove the back from your TV. Unplug it of course. Take a look at the power board. Check for any obvious damaged components. Post some good pictures of your boards with your question. That way we can see what you see. Use this guide iFixitでの質問に画像を追加する方法 for that. you will also need a multimeter to do some voltage checks. Start by checking the fuses on the power board (P board and A board is the main board)

Your comment is helpful and I appreciate it. However, I don't think I can personally do this repair. Think I will need to consult a professional. Already replaced TV so may let someone else try to fix it. Thank you so much. Hoped there was an easy fix I could perform.

@patterlin and blink code from the power LED?

I am not clear if this is another question regarding a blink code or just an error. I never get any kind of blinking though. The power light comes on for 3 seconds and then the tv turns off.
