It will be best to contact the authorized service centre for Samsung in this case. It sounds to be a main board fault. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. Surf the site with patience.

Samsung tv ln52a750 when turning it on it chimes, red light flashes, and then it clicks and shuts back off, and then just keeps doing the same thing over and over. tried unplugging and is still doing it.


These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can vet 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.

Clicking tv wont turn on


you could have several things going on, I would suggest you start with checking the power supply capacitors. If you see any with bulging tops, have them replaced. This is the most common cause of the clicking problems.

A blue screen will in many sets trigger it to shut off---try unplugging set and or box or receiver if used for a while and plug them back---allow the units to try to reboot.

My samsung lcd tv cycles on and off continuously. It started after I turned my samsung blue ray player on to eject a dvd


I replaced (2) capacitors which I purchased at Fry's Electronics for $1.99 each. It took me 1 hour to complete the entire job. You must remove the cover, and disconnect processor board.
