TELEVISION WILL NOT CUT ON

Most likely it's a capacitor fault triggered by the power cut.

Google "Capacitor bulge" and then search Youtube for your make and model to see if anyone has done an instructional video. You'll need to be comfortable dismantling the TV and be able to use a soldering iron. If this isn't you then take it to a repair shop.

Fuse inside tv or power supply most likely fuse

If the tv is not a plasma unit which are expensive to run I would not be bothered completely turning off the power. I have a power supply readout connected in the mains power and Like you I believed the hype about switching every thing off but I learnt that the cost is virtually nill. to run. For a example I have 2 moniters + 1 computer+1 printer +1 tube type TV+ clocks( all on standby) + night light and the cost is .001 cents /kilowatt hour.. IT climbs to .002 cents when the 2 fridges cut in then drops back when they cut out.. Another point is when you continually switch electronic units on and off they will suffer more failure than leaving them on stand by

power supply ?

have you tried checking the power cord?

Dry goint on powersupply somewere.

i have a rca television and my t.v. just cut off when i was looking at it and , when i tried to cut it back on, there was no sound and no picture and the power button did not want to cut off on it's on i had to unplug it.

Check the internal fuses AFTER eliminating power supply, power strip, etc. But it sounds like it is in sleep mode. Try unplugging it, wait 5 minutes then power up while holding the power button in.
Good Luck!
