I turn the tv on but it turns off

When i turn the tv on it will turn off what can be the cause of that

ANSWERS:

"@sugamama bad power capacitors on the power supply can cause that. However, there are plenty of other things that can do the same. You got to start somewhere, so you might as well remove the back (unplug your TV) and take a look (don't touch) on the power supply.

Check for domed, leaking caps. Post some images with our question so we can see what you see. Use this guide for that."
