Samsung UA50F5500 50" LED TV does not want to switch on. Remote receiver LED flashing all the time.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

Is it a new set? Has it lighted before? Return it DOA to the seller. Change batteries in your remote, maybe it will reset? If it won't switch on manually, its the TVs fault.

Try a different power outlet. Is the player connected to the TV correctly and is the TV on the correct input?

These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs.

Just count the number of flashes occur at one time switch on.

Try resetting the TV by disconnecting it from the mains outlet for 1/2 hour, then connect to the main outlet and switch on the TV.

Hello

In time as the Sony Trinitron ages it begins to have power issues. While this can be true of most tube televisions it's the rate and severity at which this happens to Trinitrons that makes it particularly of note. Many Trinitron owners have complained of the Trinitron set turning itself off randomly and frequently. Some sets have failed to stay on for longer than a few minutes at a time. Eventually some sets will not turn on at all. These problems grow more severe with age.

Check the power cable running from the Sony Trinitron 32. Make sure the cable is completely inserted into the power connection on the rear of the TV as well as the local power outlet.

Disconnect the power cable from the electrical outlet, then plug it into a different connection. It is possible to electrical outlet has died, forcing you to obtain a power current from a different source.

Check the cable connection running from the cable/satellite receiver or VCR. If the TV is on but no picture is on the screen, the problem is most likely due to a connection issue.

Power off the cable/satellite receiver, then press the "Video" button on the remote control to switch the Trinitron 32 to the video input signal. Turn on the cable/satellite receiver and the programming now loads onto the television screen.

Most likely the set has lost vertical sweep or the feedback from that circuit. This will shut the set down to prevent a horizontal line from burning the face of the CRT. This will have to be looked at by a technician.

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.


1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Hope this may help;
