Check power settings
SOURCE: Electricity went out in town, tv won't turn back on.
On this type of problem, the first thing I check is the AC line fuse on the power supply. Follow the Ac plug wire to the power supply board and where it plugs in, you will find the fuse. If: Then: It checks bad. Replace it. It goes out again. Call a Servicer. It is good. Check for the five volts that goes to the Main PCB. No five volts, change the power suppy (SMPS) Five volts is there, more than likely the Main needs replaced and SMPS. For a Samsung Servicer in your area: 1-800-SAMSUNG

I had the same issue with my 42HP95 after about two and a half years. Same symptom, red flashing power light, reset doesn't work and most of all, the last day of the Ryder Cup starts in 3 hours. Any other time (with exception of SuperBowl Sunday). I frantically searched the web for like symptoms and came across someone that posted the fix was to bypass the Seine Module but I had no clue what that was! So what do you do? Tear off the back of the TV and look for something that says Seine on it... Right! After that failed and 500 screws later, I decided to look for a Service Manual online. Nothing like RTFM (Google it!). I paid my $11.99 for a download Service-Manual.Net and found what appeared to be the Seine Module (SEIN). Through a little trial and error, here is what I came up with. The pic below shows the location of the said Module in the red rectangle.
I ultimately found that if I unplugged the connector from the module (in red circle) and put it in the cable management loop (other red circle), the TV would power on and has been working ever since.
According to the post I read (grains of salt) the SEINE Module is only needed if you are using coaxial type (rabbit ear) antenna. I personally don't know but it works for me. Granted, this is my experience and may not work for you but for $12, I am a happy camper. BTW, what a Ryder Cup!!! USA USA USA!!!

Hi...
Main power supply is overheating. Try getting it dusted out first then check into getting it serviced

Hi Launa Sparks-Hunter, thinking about hdmi control devices plugged into tv
like a dvd player
or a x-box
or a play station
try powering these devices down for 1 minute
then power back on
