The unit has a fault on its power board and sustain board.
It turns off because the sensor is preventing some component from bacoming overheated and catching fire or damaging further components. Seel professional repair.

Sounds more like blown/exploding capacitors on the PSB-Power Supply board. No OSD-on screen display a blinking led or chatter/relay clikcing at startup is the tv going into fault protection and bypassing the startup pins. The YSUS-Main controls the pic which is attached to 2 buffer boards the YBU-upper YBL-Lower. They control the upper and lower portion of the OSD and the YSUS controls both of them. Since you're getting No OSD you need to check for blown caps on the PSB first. Unplugging the set resets the error again. So you start all over again.

SOURCE: I have a Samsung 56"
Actually the Samsung model you have was the first model to come out in 2006 that did not have a color wheel. The LED blinking is actually a self diagnostic program of sorts. Depending on which lights are blinking, and how often, the service manual will tell you where you should start checking or replacing parts and assemblies. I do have most of the codes, so can you tell me if the if the LED light is the only one flashing, how long it flashes, and do any other lights flash at all? Thank you.

I would suggest replacing the board itself, chances are what caused those fuses to blow is still faulty. did you check those fuses again after you powered it back up?
