How to fix power on problem?
This can be a result of a stuck button on the TV or remote. Remove the the batteries from the remote to prevent a signal from it being sent. Operate all the buttons on the TV one at a time in an attempt to "un-stick" any stuck button(s).
Press the power button on the TV to see if it will turn on. If it does not, check for an open fuse or tripped circuit breaker. Check for the presence of power at the outlet by connecting a table lamp or other electric device. If power is off, see if a wall switch is off somewhere - as it is not uncommon for a switch to control 1/2 of an outlet.
Make sure the power cord is connected at the TV set. Many power cords are completely removable and the end the connects to the TV may have been loosened or fallen out. Visually check the length of the cord to make sure it has not been damaged or cut. Do not use you hand to feel for damage unless the cord has been unplugged from the outlet first.
Unfortunately, if you're unable to turn the TV on; it will probably need to be serviced professionally. There are typically no user serviceable parts inside the TV itself. If your TV has a fuse holder on the outside of the TV, you should unplug the TV and remove the fuse for replacement if found to be open or blown.
Lastly, operate all the buttons on the remote - again to un-stick any button. Return the batteries to the remote when done. If your remote has a lamp to indicate when a button is pressed, check to see if it is on with fresh batteries. Old batteries may not show the lamp being on, but still allow the remote to send a signal.
