Question about Samsung HP-T5064 50 in. Plasma HDTV
I have a samsung hp-t5064 that show grainy picture with scanning horizontal lines. TV repairman came and looked around the back. Opened it up, replaced some boards, don't know which, I was not around to see exactly what he did, the TV belongs to a family relative. His recommendation is to replace the panel. That's not an easy pill to swallow being that it's approx $800. So figure let me open up the back. Look around. Didn't see any bad capacitors. Not too sure about the fuses since they are covered in paper. What do you think?
You can also check for poor connections on ribbon cables etc.
Socketed Chips etc.
Modern TV's are more "Computer" than old fashioned TV. You could have memory problems, CPU or timing problems. Power supply problems.
Did the problem occur overnight. Like On/Off... or has it gradually gotten worse. All of these things can be clues. Does a slap on the back cause any glitches or changes to picture. If so then it could be an indicator of a physical problem like a poor connection.
Suggest getting a second tech's opinion before any replacement

This should be repairable. It may be the LVDS Cable or the Main board problem. The only other problem is the T-Con Board.

I just had my HP-R4252 repaired on 12.05.09 with a similar problem. The picture is covered in horizonal, broken lines and the color is predominately red. They lines are grouped together in large bands across the screen.
The tech replaced the Y-Buffer boards (Up) and (Low) in about 20 minutes.

Do you have more specific information on your set, such as the full product model? Such as: HP-R4252X/XAA? What about the version?
This can help, because--as of right now--you are telling me that you put that Philips part into your Samsung TV. The LJ41-02759A is made for a range of Philips sets. They may work, don't get me wrong, but the part # for your Samsung set is: BN96-02033A
I don't have both these boards in front of me, of course, so I can't tell you if they cross or not.
Hope this helps.

Did you find out if that would solve the problem? I was really excited to learn that all I needed to do was change out the capacitors but after installing 4 it continued to click. I to removed the cover to the and found the relay where the noise is coming from

In almost all cases where the set is taking a long time to turn on and then turning off it will be the Power Supply board that will have bulging capacitors, usually three to five. Look on the upper right side of the Power Supply and look for any blown caps. You can replace these caps and you will be fine. Now the other cause can be the Power Switch is shorting out. You can disconnect the the Power Switch but not the IR sensor and then turn ON the set with your TV remote and see if this stops the problem. If you are not skilled in component level repair on the Power Supply board then buy a new Power Supply board and install it.
