Samsung plasma. How do I remove the PDP ribbon connectors from the E buffer board

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. or..no picture they could both be blown..an 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.

I have a plasma tv that has two black lines about 50mm wide running vertically in the centre of the screen


Three kinds of detects count for this problem. It could be the Logic board, or the Logic Buffer board, or the PDP panel. Just drop your tv to the warranty depot shop to repair.

Samsung 60 inch plasma has developed thin vertical lines top to bottom. Changes colors rapidly. Lines are increasing from one to twelve now. Could buffer boards be fault?


Buffer boards could be at fault. Also the connectors to the boards. On more than one occasion I have put a wedge under a buffer board to make a better connection. A good repair man will test the connections as well. Main video board could cause this too.

Problem with picture on HP Plasma TV


hello!
This is known problem with PDP displays. That means: one of X-buffers has bad connection to the PDP(plasma display). Or, in some cases, depend on PDP type, it could be panel itself at fault. You need to open your set carefully and get an access to X-buffers. Usually, at the very bottom of PDP, covered with aluminum heat sinks. By turning set on, while face down, start tapping slightly with isolated handle of medium size screwdriver. Observe, when line(s) vanished. That's where connection(ribbon cable) between PDP and X-buffer is compromised.
In some PDPs, those integrated into panel itself and nothing you can do, except to live with that or replace panel. Hope, you end up just reconnecting ribbons. Anyway, you must have very good technician background to do so.
good luck,
Alex.

Sonicview vpw425 has red and green snow


Hello!
Good question: this problem caused by aged capacitors in Y-sustain module, plus in a power supply. Bad news: if you keep watching TV, it will quit soon with hefty repair bill. So far, all those modules are in repairable condition. Plasma has very high voltage inside and I won't recommend you to even open the set, unless you are have very good technical/electrical background. If so, let me know. I will guide you throughout the repair. If not: pull the power supply board out, then Y-sustain board. Left side of the set with back open. Y-sustain is a quite complicated to remove off the set. Has many fragile connectors to scan converters, plus ribbon cables. Some might be well hidden. If you forget to unplug those, damage will occur. I, personally, won't recommend any amateur or even mediocre electronics technician, to mess with early plasmas. They very well built and packed inside, multiple rubber heat conductors under those boards, etc. Most likely your set has Samsung PDP, because Panasonic PDP, which has been used in Toshiba as well, won't show this problem. It might intermittently loose a picture, but not a "flies" on a picture. I've seen those, in 50" Samsung and their made panels. Guess what: whoever ignored my warning: fix it now or forget it, already got set busted.
I can help you to rebuild those boards, but you need a service manual to safely remove and replace those.
Thanks,
Alex.

I have an LG Plasma Model#DT42PY10X. IT HAS A RED LINE RUNNING DOWN THE RIGHT HAND SIDE AND i WOULD LIKE TO KNOW HOW TO FIX THIS PROBLEM. THANKYOU


Hi:
If the line is less then 2 inches wide this us a good indication of a bad PDP panel (Screen) usually very thin lines indicates a failure in the screen itselg, altho you might try replacing the upper and lower buffer boards to ensure its not the screen. You might want to take off the back and try reseating all connectors leading to the buffers and the Digital board. But in my experience thin lines less then 2 inches usually results in a bad PDP.

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.
