Question about Samsung Televison & Video

Open Question

I have a Samsung 4 490 3D plasma tv (model PN50C4903D)

I'd like to change out the E buffer board on my Samsung PN50C4903D plasma tv but I can't see how to remove the (x10) PDP ribbon connectors to the buffer board. The board is an LJ41-08388A Do I pull them off gently or do I have to use a heat gun or something? I've never taken this kind of ribbon connector off before and I don't want to damage these delicate parts and screw up my chances of successfuly replacing the board because I've damaged a connector. Any advice on this please?

I doubt that moisture damaged the SMPS bd.
There are many circuit boards in your set and it will take a trained samsung tech to find the problem.

SOURCE: no picture, just sound, blown y buffer board twice1

a4.. there are 2 of them, upper and lower buffer boards.. they control the top and lower half of screen devided horizontally, i have had many run ins with these sets. and usually the buffer boards arent cheap.

they plug into the ysus( y sustain).. its possible your y sustain is blowing the buffer moduals because one of its i.c.'s under the heatsink has popped on ya.. effectively creating a short that blows the buffer boards.
remove the buffer boards, turn tv on... feel the 2 silver heat sinks on that y sustain( beware dont zap urself.. just the tip of your finger on the heatsinks)

you may find that one is cold and one is hot...if so, you need a new y sus and probably to replace the buffer boards the a4 upper and a4 lower.

If you get a new ysus.. plug the a4 upper and lowers into it, look at your picture.. if ur missing the top half the top buffer is blown or lower half the bottom buffer is blown. picture they could both be easy way to tell if u have no picture to diagnose is..touch the heatsinks that sit over the chips on the buffers..if they are red hot.. they are bad and shorted internally.

In most of the case is the data buffer located on the lower bottom of the Plasma panel is damaged duo to defective buffer IC, or it was damaged by leaky liquid dripped to it. Some older panels you may change the buffer board, but newer panel, the buffer board is directly soldered to the panel by a few flat flex cable, you can not change it.

How to fix Black Horizontal Line on Samsung Plasma TV (PN60F8500)

It is possible that the buffer board will fix your problem, but try removing, cleaning and reseating the flex cables between the buffers and the panel first. All it takes is a little bit of dirt or oxidation to open a connection and cause a line-out condition. Use a lint free cloth and a little bit of alcohol to clean them. Make sure to fully insert the cables and center them perfectly in the connectors or you will have even more lines. If the original line is still there after cleaning, then try replacing the board. Buy a board from a reputable dealer that will guarantee no problems with the board. If you still have the line even after changing the board, then the plasma panel has failed and the only fix is to replace the panel.
Always let the tv set for an hour unplugged before attempting any repair work. There are dangerously high voltages in plasma tvs that can cause severe shocks or even *****.

Hi I have a samsung plasma PN50C550G1F I havve right now 2 vertical lines that seem to change color with the background picture. Tv powers up fine sound work perfect.

Vertical lines on a plasma TV are caused by either a failing x-buffer board or a loose connection at the flex cable between the panel and the buffer board. Sometimes just removing the flex cable, cleaning it, snd reinstalling it will fix it.

Anyone know why the Samsung PN50B550 50in Plasma would have a vertical strip about 2 inches long on the far left side that keeps going to static/out of tune. The rest of the picture is fine. I've checked...

I had this issue..Go to Menu and go to the burn in troubleshooting and run the scrolling feature..Scrolls whites and darks..Run for an hour..I had it on both sides..From watching 4 X 3 pic, image retention..Should clean up fine

My 50'' Samsung Plasma has dead screen after only 2 years

welcome to fixya!
without doing voltage checks, my best guess is this:

Plasma hpr5053 or hps5053 models will burn out a buffer board or both, there are two buffers and the Y board.
I usually change all 3 at once, but if on a budget you can try to remove one buffer and see if you get half picture (upper or lower)
this is something only a technician should attempt. the boards cost $200 each (buffers)
$300-$400 (Y board).
if you actually get half a picture the Y and one buffer are good, a bad buffer usually burns out the Y board. and in really bad cases the panel is bad also (not common, but possible)
For part#s , specific help you can post a model# , but again this is a repairmans job not something the average customer can fix.
hope this helps

bad y buffers , your model may have only one y buffer and you may need a Y main too. voltage checks can confirm VS and VA voltages marked on board plugs and tag inside TV
