Picked up this 50" plasma tv today for nowt, but right hand side of the screen has 3 vertical bars about 3" wide 3" apart from each other all the way from top to bottom, first one is all different coloured lines, next ones black with a green line down it and last one (very edge of screen) is just white, is it most likely the tcon card, a bad connection on ribbon to the actuall screen or is it just shot and only worth breaking for parts?

Re: Samsung ps50b451b2w vertical lines on screen
Run the internal test patterns via the jumper on the control board. Long shot but may as well try.Comment

Cheers for the replies guys, I'll have a look this week if I get chance, may break it for boards tbhComment

Re: Samsung ps50b451b2w vertical lines on screen
Found the problem, the far right strip of lines are because the actual first vertical screen connection has come away/unglued and pushed back from the bottom circuit board all together (labled 50u1p logic buffer_e), as for the other two rows (multicoloured lines) I'm guessing it's a fault with the same board or the logic board with the lines being in 3" wide strips
Can the logic buffer_e board with the glued screen connections be replace with them being glued or should I just break it for parts as it all works bar the screens linesComment

You could always try 3m 3703 conductive tape.Did I leave the soldering iron on?Comment

Re: Samsung ps50b451b2w vertical lines on screen
9705 seems to be the right number as that other number comes up with a box tape

Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed... -
Hello there, ive recently found an older 55inch Samsung SmartTV.
Sadly it has vertical lines at the left and one line in the middle-right.
I have already tested out the connections and have looked at the soldered ribbons of the LCD panel to see if some contacts got loose by pushing them a bit but with no success.
I have factory resetted the TV as well but also with no luck.
I am afraid that it is indeed a LCD Panel issue but there are NO scratches or any impact-marks..
A similar issue has been posted as well but also with no actual response ... -
Hello all, I'm dealing with a Samsung LE32C530F1W that now has vertical lines on the right side. It started with a ghost image on the top of the screen and then I tried the old trick of masking a few contacts in the flat cable that connects the T-Con board to the screen with some tape. It worked for a while and now out of the blue it turned into what you can see in the pic. I was able to get my hands on a known good T-Con board but the problem still persists. Now, what I've noticed is that the cooper colored flat cables that are directly connected to the screen itself are very hot to the touch... -
Hello Everybody,
I have a 40 inch LCD SAMSUNG LE40A656A1CXXE. Its problem is that there are Vertical Lines on Right Half of The Screen.
Interestingly enough, when I move my mouse (in the case if connected to a PC) or when I am watching the TV, lines also move. At first appearance, I had thought that the problem might arose from loose vertical ribbons (COF), but when I opened up the TV for further investigations, I realized that the problem cannot be solved by touching them.
Moreover, I detached the T-CON board for a new round of investigation. I personally... -
Thanks for offering your assistance with this. I'm an electronics enthusiast with moderate level of competence (have a decent lab with two power supplies, microscope, DSO, hot air, good iron, can competently work at a component level on SMDs, design and solder own PCBs etc). I really enjoying fixing things and learning new stuff so took up a free 58" LED TV and have been googling and watching Youtube videos to see if I can fix this! I am happy to go down to individual component replacement/strip replacement etc - it's all in the name of learning.
The issues are as follows: the...
