Samsung PN50A550 Plasma TV started clicking on & off then quit. The blue lamp stays on and the red power light blinks with occasional loud clicking similar to normal power on-off sounds. We had a power bump the day before and the tv clicked on and off several times erratically for the first time ever. I've had it on a surge protector if that makes a difference? It seems to be stuck on until I unplug it, though there's no picture or sound-though the screen flickers light occasionally with the activity when plugged in. It's 13.5 months old-1.5 months PAST warranty!

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/

power suppy needs replacing...according to samsung and other forums i read when mine did this its a common problem

Yes its likely a power supply issue then anything else, if you know how to fix this then you can buy a replacement by calling the manufacture otherwise take it to a autherized service repair center, you will be happy you did because a new one would cost you so much more money!!!

You need to replace the power supply board. The new ones have a bigger heat sink - obviously JVC knows about the problem because they made the new ones bigger. It cost $250 from JVC and I installed it myself - took about 3 hours to do. If you are not tech savvy call a repairman. Hope this helps.

If you dont have the manual, download it from internet. It should tell you what the blinking light is indicating. My friends tv was blinking 3 lights around power button and the manual I downloaded correctly stated it was the lamp that needed to be replaced. I also found some other interesting info via the internet. There is a way to get into the Service Mode of a Samsung TV. Try doing a Google search for Service Mode for your model... Good Luck. PS the lamp itself was pretty expensive but installing it was not hard to do.
