I would first suggest you try to unplug the device for an hour or so as this many times resets them, and they work after that. It's the easiest (and free) solution, so I always suggest that you start here.

If this doesn't work (you may have already tried it even) I think it's time for a service call. Make sure you don't have your display plugged into other devices that might be switching off power (like triggered receivers, etc.) or a circuit that's being over-loaded with other things on the line.

Also, if you have other Samsung components and using Anynet+, might try disabling that in the display as well as the other components. I avoid any proprietary features like that. They often cause as many problems as advantages.

However, I am pretty sure you are having a power supply fault issue, for whatever reason it is very common with Samsung TV's... you will probably end up having to call Samsung and schedule a service visit, the good news is that in most cases this can be fixed for less than $100.

Samsung's contact information for support is: 800-726-7864

Hope this helps, thanks for your time,

Tim G

You have a problem on your Power supply board, possibly a bad capacitor or loose connection. You can look hard at your power board and check for these things or replace it from places like shopjimmy.com or discount-merchant.com etc

Got to Samsung's support site and fill out a request:
http://www.samsung.com/us/support/service/request

You will be contacted by your regional repair center. I'm located in Milwaukee, WI and was contacted by a repair center in Elgin, IL, which is 60 miles away.

The regional center said they think it probably is a electrolytic capacitor issues, as multiple models of Samsung LCD's have this issue. They have defective (too low voltage) capacitors which will eventually give out. Unfortunately he said my model was not on the list they have for a free fix. He gave me the number to Samsung's Executive Customer Relations department, which I then called immediately. The woman there checked and found that my model indeed was covered - she updated the Support Request, and instructed me to call back the regional repair center.

I called back the regional repair center (immediately after finsihing with the ECR) and got a different person on the phone, and gave them my ticket number from my original request. He said since ECR updated it stating my model was covered they would fix it for free. If it's not the capacitors that are causing the problem I will be charged a 150$ fee, plus any parts required to fix the TV. I agreed to that since my local TV repair quoted me 200$ to fix the capacitor issue alone.

Today is January 25th, they have me scheduled to have a repair tech come to my place January 7th to do the repair.

You can fix the capacitors yourself for very cheap, maybe 20-30 bucks if you don't have anything: soldering gun/solder/flux/capacitors/etc...

I'd just go through the service request path, get it fixed for free and have a professional do it. Total time for me was 2 minutes for the service request, 10 minutes on phone for regional repair center, 10 minutes for ECR, 5 minutes for regional again. The repair is expected to take 15 minutes - most likely they'll just swap out the entire power supply board rather than the individual capacitors. Basically 1 hour of time to save minimally 150-250 dollars. I bet not many people asking to fix this make 150 bucks an hour...pretty simple math I think.

Power won't come on- constant clicking loop instead


My T.V. did the same thing and it was due to bad capacitors on the power supply board. the tops of the capacitors were bulged, once replaced it worked fine. It involves sodering in new capacitors total cost $30. that includes buying the sodering tool. Keep looking around on line someone had pictures step by step how to do it.

Clicks on and off several times before staying on


The power supply will sense if the set is 'drawing' too much current and switch itself off. This could be the case here. The power supply board may eventually go completely bad.
