Try and unplug it for a while so that it can reset itself and it should work. If that does not work, try pressing and holding the power button in. And if that does not work, You may have a circuit board short that only lets it come on at certain times so that it will not catch fire. You might need to get it checked up in a shop to confirm the suspicion and to get it fixed.

Try a hard reset first - Unplug from power source for 1-2 hours, the replug and see. If this does not work, it could indicate a fault in the power board which will require servicing

There is a sub-board in this set that powers the convergence circuit. Often a big Ic shorts, two diodes and finally the main fuse. not something you can fix yourself.

Light


My RCA 52 inch was doing the same thing.  TV guy had me use a regular hair blower blowing very hot on the power supply board ( bottom left in back). After a few minutes the tv would come on.  He replaced 2 capacitors, charged me $100.00, plus the $95.00 service call, and is working fine now.  This was a month ago.  So far so good.  He only took the board to the shop, not the entire tv.  Hope this helps.
