Samsung 3D tv model code UN60F7050 started turning itself off/on again every couple minutes. I've done a factory reset, now it runs for 2 hrs, then starts turning off/on again until I do a reset again

when unhooking the battery turn key on all the way to run position and leave that way for about two hours and then turn off and remove key and hook up battery and start engine that procedure drains the backup battery in the computer and makes it relearn back to factory settings basicly reboots

Lock the doors then unlock the driver door with the key. My 03 mustang has done that several times too

If you think the problem is the security system. This is for programming with no keys.
Use a scan tool to verify that the numkeys pid value is less than 8.
Use a scan tool to verify that the sparekey pid value is enable or yes.
Insert either the remaing key or a new cut key and turn to run.
Use the sacan tool to navigate to pats system and then choose security access. The scan will count to 10 minutes before the model will allow you in, once in, choose ignition key codes erase.
Did connect scan tool and turn key off. Inset key and turn to run for 3 seconds, then turn the key off and remove. Insert second second key and turn to run for three seconds, then turn key to off and remove.

Unhook your battery again for about 15 minutes. After you re hook it up, let car sit with the key in the on position, but not running. Let it sit for about 5 minutes, and then turn key off, and start it. It may run rough for a few minutes as the sensors and systems are all resetting. If you try running it right away, or cold, it can confuse the regen process

The only alarm system I've had is my 12ga with deer slugs.

It shouldn't be too hard to either turn it off, or find the problem power supply. I am thinking the power to the house may have blinked off and on at some point, and the logic of the alarm is freaking out as a result.

Is there a backup battery for the alarm system? If not you could try turning off a circuit breaker at a time until you diagnose which one is powering the alarm system. If you find one that turns the alarm pad off. Leave it off for a few minutes and turn the breaker back on to see if it will reset itself. If the alarm has a battery backup try to remove it and again turn off the circuit breaker. Also search your book for resetting the alarm system.

put some 2T oil in tank every other full tank ,seems to cure my diesels i have about 2/3 hundred ml will do it .

If I recall the radio locks itself after 3 wrong codes are entered. Disconnect the car battery, or the radio itself and plug it back in after a few minutes. I should then ask for a code when you press the power button.

check fuel pump pressure

Hello now that I see this messages you making me to remember when this use to happen to me I was totally mad especially that I try everything even on my wedding Honey moon it was a disaster I took my truck to my Honey moon it was 12 hrs from home but it took me around 20 hrs once I get back home from my trip I decide to spend a full day trying to find out what was wrong with my truck I had a dodge ram 1500 1995 5.9 engine and the main problem was with the fuel pump it run fine for about 3 hrs and then it die and I had to wait around 20 minutes and then run another 2-3 hrs in low speed the higher the speed the less time it took to fail again how I found it was the pump well inside in the engine compartment there is a fuel line with a valve to check the fuel pump pressure I did run my truck hard until the fail occur then I install the pressure gauge try to turn the switch on and it was no pressure at the line problem solve the fuel pump was getting hot after couple of hrs running sometimes it only took about an hour to fail try this and see if you have the same problem it could be a different problem but it is good to know this

It sounds like either alternator or computer, I f you can get it to run on its own pull the positive battery cable off the battery and if it dies its your alternator. And this is no real way to check the computer except going up to a AutoZone and they can check codes for free
