Sansung un55c6500vfxza turns itself off and on

Hi Jim, Some years back I received a 46" Samsung LED TV with the same problem. The main board was faulty in that case. Power on 5V line was short to ground and I had to replace The main board. I hope it helps. Good luck.

go to factory reset

Sounds like main board fault. Contact the authorized service center for Samsung. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box.

hi;
when your LCD TV wont start , even if you press the power button , it has a power supply failure, maybe some capacitor has bloated or changed value, try to watch this http://www.youtube.com if you know how to solder, or even disassemble the back of LCD TV. if not try to call a repair technician. thanks ,, hope this help........

check for the return fan motor wire  signal for pcb 

If you mean Samsung not Sansung, this try this.. *2767*3855#. There's a china mobile with the name Sansung, so I was just confused. Good luck. Thanks for using FixYa.

That actually is a flaw in the Sansung phone itself, its something in the manufacturing. When getting large messages or multimedia messages the Samsung will power itself on and off. Had the same problem with Samsung.

first check voltage to hv transformer if volts probably loose contacts on magnetron ,cap ,diode if still change magnetron
