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.
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.
