Samsung PS-50C91H 50" plasma no picture


If this set has a cable box, satellite box or even a receiver hooked up to it remove power from them and the set for a while and power back to see if a reboot cures this issue.

short of that someone who is willing and knows how to check things is going to have to look inside and test things, repair if not what I have suggested consists of replacing boards which can either fix the set or not and gets expensive.

I have black horizontal lines (left to right) from about middle to bottom of screen and I want to know how to fix it. Sound and picture work...just those line remain. Model # P50H401


Hello.
It looks like problem is originated near buffer board/s.
You can try to repair this but it is not recommended for untrained person.
If you remove back cover of your TV on the left hand side you will find ribbon cables that connected to narrow and long buffer board (or two boards) with one end while other end goes inside PDP (Plasma Display Panel). Poor connection could be present on any side of that ribbon cables. You can try to "play" with ones that are visible and see if it will clear the picture while TV is turned on. But this is not safe, there is about 200V running on some boards so you have to be extremely careful. If poor connection is on the other side of the cable - than issue is impossible to fix without replacing whole panel. And this is more expensive than just buy a new TV.
I would recommend let professional to take a look at it. Your health and life is not worth of any TV set out there.
regards.
Russ.

2 BIG THICK LINES ON LEFT HAND SIDE OF THE SCREEN..


If the lines are vertical and go from one side of the TV to the other, it is most likely the scalar boards. There could be a loose connection from the PDP module (plasma panel) and the scalar boards. Otherwise, the scalar boards need to be replaced.

If the lines are horizontal, then the same thing as above except for the y-drives instead of the scalar boards.

Thin black line


Try to replace the YSCAN board. If not fix it, then it's the PDP Panel failure.

Vertical Black line 3 inch width on Plasma Samsung 42C96HD after 2 months of use


I also have the same problem I phoned Samsung today to explain the tv was only 14 months old, they didn't wanna no because it was out of warrenty by 2 months. I am getting a black solid line down the left hand side of the screen. I ended up phoning Dixons were we bought it from, they have told me to get an independent engineers report done & send the report to them within 14 days. Dixon told me it was a known problem with Samsungs. They said they will fix it free of charge if they can if not they will send vouchers to the same value of the television. So beware stay clear of Samsungs.

Pioneer PDP-425CMX 42" Plasma Tv


Try the scan PCBs that run down the side and the connectors that hook them up to the rest of the system. That would be my first place to start.

Unfortunately I don't have service manuals for non-european models. What is the date of manufacture?

Black line in center of screen


These black lines on the plasma screens are very fixable.  There is a dry solder joint on a circuit board at the bottom of the plasma that needs resoldered.  There are 6 or 7 "ribbons" along the bottom of the screen that correspond to vertical sections of the display, so you just follow the black vertical line down to figure out which one is faulty.  I just performed this fix successfully on my first attempt on a Gateway plasma, but it will work on most plasma's, specifically Hitachi, gateway, LG, Hyundai, & Akai. I think they may all have LG boards, my gateway did.
I can't really describe very well what to do, but I assure you it is fixable.  If anyone is near nashville, I might be able to help you out.  My email is tomp2000@juno.com.
thanks,
ST
