The set should have a vertical output IC,You need to change it ,maybe you can check the B+ going to it because it might have opened the safety resistor if the IC went bad.You can check for broken board too unless the set is never move from one place.Be carefull when checking voltages ,there is still high voltage,not much but can num your whole hand.

Samsung pn51d440a5d thin black horizontal lines across complete screen,2 to 3 inches apart,replaced y sustain and y buffer pcb


These lines a are technically called as 'vertical retrace' lines. There will be thin white horizontal lines, at about 1" apart, all around the screen. Even though, you've decreased the brightness and contrast to its minimum, these line will be there. There are many reasons for this fault. If the screen voltage is more than normal, or the supply voltage to video output transistors are less than normal [due to faulty smoothing capacitor], this fault can occur. If you're sound in electronics, check this link. It has details about how to check for this fault. http://electronicshelponline.blogspot.com/
Pull up previous posts by its left sidebar, or type in the brand name and model number to of your set, to its search box, and press 'Enter' or view it in Mosaic / Timeslide option.

A horizontal thin black line has appeared across screen.


hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works
