If its flickering in just one of the sometimes 15 ccfl light tubes youll need to find the right one and replace it this is tricky and involves dismantleing the lcd panel VERY carefully
at very least using a AC voltmeter to ident the tube thats rawing too much current as the TV will flicker the whole panel if just one strip is wrong and feeding back too much voltage to the lamp detect circuits etc,, on the psu board

here is a you tube search
youll find lots of similar lcd type ccfl with similar issues
my last type was LE40R88 and it had 5 bad tubes
you can just replace them all with led bars and youll find this detail on you tube also

sometimes this is a psu issue and again can be tricky to find
you can find a psu board thats ok on ebay and try that
beyond this its a ccfl issue {i think }

forinstance most B grade stock uses 20,000hrs lifetime ccfl A grade uses 50,000 hrs type
their is also several sites in HK and USA stock replacement tubes
but are not cheep however are 50,000hrs types or better

I have a 50" samsung tv that flickers but has no picture or standby screen. I replaced the power supply board but it did not fix it. What else can i do to fix it?


If you have sound I would consider changing the t con board since it is solely responsible for video issues. I assume that your back lights are working since you are getting some flickering..

Screen has started to flicker constantly. tv is 9 months old. When switched off flickering stops for about 5-10 minutes and then starts again


I had the same issue occur on my ln55c650 and they had to replace the power supply pc-board. Seems some issue with power module in the TV rather than the side panels. Luckily for me, TV was still in warranty.

When i turn on my samsung lnt5271 the screen seems


This sounds like a repair issue. I do not believe there is any in-home troubleshooting that you can try that will fix that particular issue. I would call Samsung tech support to see what their opinion of the problem is. Their number is 800-726-7864.
