    I'm disappointed to hear this. Samsung LCD's have a notorious and well documented problem with faulty capacitors. this problem makes the tv click and click until it turns on. I had this problem and fixed it myself by upgrading the bad capacitors. Very easy to do and many how to videos on youtube, but you are better off calling Samsung. If this is the same problem, due to a class action suit, they will send a tech to you and fix for free! my friend has a 46 from 2008 and they came out and fixed no questions asked. good luck. i was just looking at a new Samsung too and now i'm worried. thought they fixed that by now!!

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.

SOURCE: Samsung 4254 Plasma keeps shutting

I just picked up the same tv today I noticed after a couple min it shuts off and clicking same as yours. I took the cover off and it seemed to stay on longer but same thing. Then I tried running a small fan next to the power supply and It ran no problem for an hour straight you can try this without taking the cover off and aim it at the top air vent on the back cover. Runs flawlessly now. I am going to Look into stealing a fan out of another plasma I have laying around or ordering one that will match a voltage I can splice into off the power supply board preferably the smaller the voltage the better. It's a pretty crappy design for a samsung. I don't know if this will help you or not but good luck.

Usually the power supply is bad. Just 3 capacitors 1000uF 35volt rating. The 3 electrolytic caps will be puffed out, simply replace tham and you will be back in business.

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.

TV comes on and then shuts off,and a small red l keeps flashing.


If its flashing red repeating groups of three then the lamp door is not detected .
If its flashing in groups of four then a fan is not starting.Look in the vent in the back and spray some canned air into then big fan on the left(looking at it from the back) .That fan may be failing and has gotten to a place where it can't quite start again and just moving it a little with some air will make it work for a while.
If its not one of those two things let me know.
