I'm sorry to say I had the same issue with 1 of 2 monitors I purchased. I don't believe it's a powersupply issue b/c I swapped powersupplies and the issue still occurred. I had to RMA my bad monitor. I will say though, if you get one that works, they're really quite nice.

I haven't had that or any other issue w/my Samsung. Without additional information, I'm not comfortable advising you on any specific fixes. You could try Samsung's website and contact customer support.If you have a pwr supply issue, you may need to take it out to an electronics repair shop if your warranty is expired, or return it to Samsung if your warranty is still active. Sorry I couldn't be more specific. Good luck with resolving your issue.

Is the signal flickering. Or just out not receiving. If it flashing or flickering you probably have a cable problem. If you no signal the box may have a bad output

I have the same issue and it seems pretty common on the reviews. Any idea where the drivers are that would fix this? Which one does the trick?

Assuming you have power to the power supply, the power supply most likely needs to be replaced. I would check for a loose connection before I ordered a replacement. Turn off the power before you go poking around with a screw dirver :)

Yes, i have a 500+ power supply inside this puppy as we speak. It was extremely tricky and seemed impossible for me to get my power supply in so i like ziptied it and that caused it to bluescreen, you need to make sure you get it in correctly and screw it in properly, though i didnt know how until i had a repair guy check it out.

I don't think the light is supposed to flicker, mine doesn't. I think yours is not working properly.

I believe it's a defective LED driver or at least one of the components in that power circuit. I had similar problem with one of the 18 units after 2 months of used. I would recommend contacting the seller to see if they can send you a replacement. I plan to do the same this week. It should not happen.

There must be a crack in the pc lines. They are set up in groups of 3 LEDs. Cut it where it's dead and apply power from other end. It prob got damaged. OR Talk to the seller. Some sellers will send a new strip/ spool

I have not experienced a problem with the light flickering. The only suggestion I could offer is to check the wiring at the plug and wall outlet as well as the connection to the base of the light. If all else fails, I would suggest returning the light.Hope this helps

I can only can give my opinion but, in any past experience I have had regarding LED displays like this is not good. Generally, you would have to replace The whole display module.... But I might be wrong. :0/

So far I haven't had any problems with red light run continuously flickering, it might have a short in it. It not suppose to work like that and I would return it for a new one. This Deluxe brand was rated high, it goes from low to high and my wife and I love it. Contact the seller and ask to return it for another one and they will honor it with a UPS return slip. I hope that help you. Aaron G.

No, the general symptom that would cause one to replace this part would be the monitor works but the image is very dark. I think flicker rate might be associated with the video cards scan rate such as 60 hertz. The higher the hertz the better the flicker rate or refresh rate. Play with different screen resolutions and refresh rates to get a smooth screen image.

Check your brightness setting. I read that one user was getting flickering when he had the brightness setting set to 75% and CPU usage was high. He didn't see it any other time. Search the net for more info. May or may not be a platform issue.

It may be a defective unit or if you added any devices (dvd drive, new video card. etc) you may need a more powerful power supply. Also make sure you are using a surge protector. I hope I am not insulting your intelligence.

i have the LN46C630 model with same flickering problem occuring just after warranty expired. technician fixed it by cutting one "jumper" (metal wire about 1/2 inch long) located on the power supply circuit board. takes 5 minutes to fix. technician said samsung issued service bulletin that told repair techs how to fix it. you can do it yourself with a screwdriver, small wirecutters. i could send a photo if you wantok, not sure how to post the photo here, but here's what the technician did for $150...unscrew 17 screws, remove the back cover to the TVfind the power supply circuit board, that's the one your TV's power cord plugs into. On the power supply circuit board, upper left corner, to the right of and below the large 46", there is a metal jumper labelled JP852 that is no more than 2 cm in length. it connects something labelled 'Input rating' and another labeled 'COLD'. the technician used wire cutters and cut the JP852 jumper. that solved my flickering issue, TV works great now. tech said that every size TV in this class of samsung has the same design flaw and can be fixed like this. good luck. i would post a photo, but can't figure it out."&lt;/i&gt;
