SOURCE: randomly switching off and coming back on by itself.

power supply board may be failing or the power button may be sticking. If it is a Samsung, it is the power supply.

SOURCE: have a samsung plasma that keeps switching itself

This is a classic "Hic-upping" switchmode power supply problem. The protection circuitry inside the SMPSU, has sensed a severe potential problem, and is attempting the shutting of the set, down to avoid a fire, explosion, or both.
This set had developed a problem, that is so severe that the set must be shut down, (This set should be removed from the Power),
What is happening is the internal "Fault" that is causing the Protection Circuitry , to detect the problem and attempt to shut down the set, keeps restarting the set, because as soon as it shuts down, the "Faulty" component(s) cool down?, and the "Fault" ostensibly "Clears" so the PSU starts up again, only for the component(s) to heat up, whatever, again and fail, so it shuts down, and if left unattended, this would continue on until the part eventually failed. As related this is called a "Hic-upping Power Supply". Any fault that involves the power supply is usually quite serious, and needs a professional, usually, unless one is familiar with servicing current day, televisions.
And in my professional recommendation, you should get a "Quote" for repair, from, an, Approved Service Center. Now, this point is very important for a good result, Always contact, their "Local" or a, "Head Office" Samsung, in your case. Ask them, for a referral to an authorised servicing center, where you ask for a "Quote". Now, when you get the information you want, then you can decide as to repair of replacement.
The reason we want an approved agent, is that way, all the engineers are trained on their own brand sets, they have seen almost all faults, and will get the job done quicker, and for less cost, and usually have parts on hand, also sometimes, there has been a service bulletin in issued and the repair may be subsided or even free. There are many, many, many reasons that display this symptom, one must work through the troubleshooting steps to isolate and identify, the Cause and repair that and any damage done.

Check all the main filter capacitors in the main power supply regulator board. Replace them all will be best.

Asko d3251 randomly stopping during cycle.


The thing that immediately comes to mind is a faulty door switch or latch. The door switch can be replaced and you might be ok. But the latch would be more tricky to check. Sometimes if dishwasher is not level or if the door springs are misalinged the door tends to slip and release the latch due to pressure. It works when you open and shut. But not sure about the night time cycle. That sounds a bit creepy if it starts again by itself. Why not put a tape around the door and then start. That will help eliminate the obvious ones. The other thing that exends dishwasher cycle time is the lack of adequate water temperature. Could be heater or thermostat or both.
You should be able to stroll through the parts by selecting categories on this site.

THE SWITCH IN THE STEERING WHEEL IS PROBABLY GOING BAD OR HAS A LOOSE CONNECTION THAT IS GROUNDING OUT AND COMPLETETING THE CIRCUIT AT RANDOM. I REALLY DONT KNOW HOW OR WHY SHUTTING IT OFF WOULD TEPORARILY FIX THE PROBLEM BUT WITH ELECTRICAL PROBLEMS ANYTHING IS POSSIBLE BELIEVE ME. ALSO TAKE A LOOK AT THE WIRING AND THE HORN ITSELF TO SEE IF EVERYTHING LOOKS OK THERE.

The television is randomly turning itself off during viewing and video game play


My initial concern would be the unit getting adequate air flow to prevent over heating. If the set is in an enclosure or even pushed against a wall this could be an issue. Also be sure the air intake for the fan is not blocked with dust which can build up over time. If the unit is turning off after running for a time I would look into this. Also the set likely has a temp indicator which would come on if the operating temperature is getting too high.

My oven keeps turning itself off


the oven may be trying to protect itself because of a faulty device that says "I'm too hot". As electric clothes dryers have a thermal high temp limit switch to protect them, look for this device (may be 1 inch round with 2 wires connected) and replace it
