I think you need a tech to repair the set.
I didn't know that Dell sold Samsung TV's, but I see no reason not to believe it (unless you mean another Dell than the big Dell). So you have 3 options to find a reliable tech: Dell customer service, Samsung customer service, a local tech. But I think Samsung customer service is the most appropiate to call.
Since you have such a busy work, why not let your wife call? Then she can make an appointment for repair at a time that suits her.
Best of luck,

HDTV - Samsung
I purchased a PN60E550D1FXZ4 in August 2012. I have never been completely satisfied with the set, but decided to keep it because of the hassle of returning an online order through DELL. The first issue was not connecting a stable internet or no internet via WIFI to the internal adapter. I did like the 3-D, price and the free BluRay and active glasses. I tolerated it as I contacted DELL with my internet issues. Of course DELL suggest I contact Samsung but I have a family, stressful job, hectic life and didn't follow through with DELL. 14 months later I wish I had. Now the real problem.
Last week I was off work and had time to experiment after reading forums and research. I connected a CAT 5/6 line from my router directly into the Samsung. My family enjoyed having netflix and other apps, finally. Then after a day it started humming, lines rolling, not correct colors/tint.... I just thought this was a result from my daughter connecting her new XBOX 360. However, I don't think so now. I have a non responsive blank screen for about 70% of the time. I then reset the HDTV and disconnect the everything, HDMI, component, and power source overnight and start over the next day. It runs for about 6-8 hours but will cycle off, on for the first hour of turning it on. Then it will constantly reboot late at night. Sometimes the red led light is constant. I realize this may be an issue with a PC that we streamed about 5 months ago. I do think it is a problem with the set or the updating that resulted from directly wiring via cable cord last week. Since then our 14 month old main 'Family' set is OUT OF SERVICE.
I don't know what to do now. My family is frustrated as for me, I feel like Chevy Chase trying connect his Xmas lights on "Christmas Vacation."
Seriously, I am consumed with this nonsense. I am up all night reading forums, Googling for Helpful advice, etc. This is creating family and work issues. I'm about to buy a new 60" LG or Vizio, but I'm still paying DELL for this Samsung. I am not a novice, nor a pro on this equipment. If anyone has similar trouble with their Samsung or have an answer to getting my Samsung back to operational and reliable condition please help.
