Samsung UN40EH5300F cycling OFF/ON repeatedly

I purchased a Samsung LED TV model no: UN40EH5300F about 1 1/2 yrs ago. In the past 3 months it turned off randomly 3-4 times but I turned it back on and everything was fine. About 4 days ago it suddenly turned off then turned back on then off and on again. It repeatedly did this for 5 min and would not stop. So I unplugged it and plugged it in. Same thing again. I read on the Internet to leave it unplugged for a couple hrs and hold the power button while unplugged for 30 seconds. I did this and everything worked again. I also read to turn off all the Eco settings and that may help so when I got it working again I did so. Well today it began to cycle on and off repeatedly again. I tried the unplugging process and this time it did not work. It still cycles when plugged in. I am out of warranty now. Does anyone know what the problem is or have a fix? It is very frustrating as my tv is not that old.

2 ideas.

1. Call it in and ask for a one time warranty extension.
2. Just extend the warranty and wait the 30 days (their rules) and then have them fix it.

Don't think that will work.

Can't purchase extended warranty after the tv's original warranty is up. And isn't the one time warranty extension only for 3 months after ordinal warranty? My 1 year warranty ended in March.

I'll try calling and see what happens

Can't know unless you call.

I know some may think it's a horrible thing to use their rules against them about the 30 day wait but hey, their rules so why not. The one time extension has been nothing I know of as to when or why or how long they will hand that out. Sometimes it seems that some of the very high end models get it more than say a small cheap model. You don't want folk posting about a 4K (UHD?) many thousand dollar TV going south at 15 months.
