Question about Televison & Video
The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

SOURCE: my Tv wont turn on
the tv may have had a break down in the power supply, or may have "bad" solder connections on the main circuit board. GE tv's were famous for this. If you know someone who can solder electronics and knows how to look for bad solder joints, this may be the fix to your problem. If you have to take it in to get it repaired, it may not be worth it, as the prices of TV's now are very very cheap.

SOURCE: power supply?
I'm afraid you are right suspecting the power supply; most modern sets use switching power supplies and they often fail when the source AC is screwy.
It might not have been the low-normal-low-normal swings but an unseen, short term surge that killed it.
The cycling is occurring to prevent a potential fire or more severe damage; a component has been whacked and the supply is detecting a fault condition, probably excessive current from some circuit.
I'm afraid you are stuck with a repair, if it was mine, I'd look inside first but some basic instruments are needed and technical background.
I highly recommend to homeowners that they install a 'whole house" surge protector. Especially in lightning prone areas.
With installation, around $200-300 US although an intelligent person can do it, it will require shutting down the home.
The surge protectors range from ~$110-200; most have a long warranty and many include insurance to cover items damaged despite the protection.
The 'Olevia' caught my eye, we bought a 47" about a month ago and are quite pleased with it.

Go to Samsung.com for solution. There is a switch that just needs to be repositioned behind access door on rear. Fixed my HL-S5086W ok.

The security system will not shut down the car while running, if the car shut off while engine was running you may have another problem. Do you have a "chip" or black pellet in your key, if so the wires going to the key cylinder may be broken at the cylinder or the key may be worn if you are having a security problem
