You may need to replace the Y-buffer to say the least. And if this is not the problem, you will need to replace theY-main board. If the Y-main board is bad you will also change the Y-buffer. Please see a Philips Tech!!!

The power supply board of the television is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
I hope this will help in solving the problem....

Here are some basic steps that will help you fixing the problem.
I'm assuming that your unit is dead set without an standby LEDlight and your outlet is live.1.Power cord - check the cord it might be opened (nocontinuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse-sometimes the fuse fail because of the powersurge, replacing with new one will cure the problem, If this is the case Iwould advice you to use surge protector/AVR (Automatic Voltage Regulator).However if the fuse blew again this is an indication that you have a shorted parts in the power supply, you may visit thelinkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction andstill the unit didn't power up then you have an open parts on the power supply.
4.If you see that the fuse is intact , don't attempt to touch anythingbecause there some fatalcomponentsstored electricity enough to hurt you with a simple mistake only. I wouldadvice you to look for aprofessional to troubleshootthe power supply. If you want to repair it yourself make sure that you havenecessary tools and testinstrument. First check bad solder joints(re-solder allcold solder), leakyelectrolytic capacitor(sometimes it has bulged at the top but not all, you betterhave a capacitor checker), open/shorted regulator transistor/IC(mounted in heatsink), open fusible resistor (caused by shorted regulatorTransistor/IC), shorted zenerdiode.
You may also replace the power supply board, this is more convenient if you are going to DIY because no soldering required. Obtain the board from your local Samsung service centers.
Also check if your unit is under warranty before opening the backpanel, it will void the warranty. Avail it because the manufacturer of yourunit will fix it for free or a little charge only. Hope I helped you. Have a nice day! Thanks for using fixya.
