I need help, I have sound but no picture. The vertical line are different colors and range in size. I have tried un-plugging, and check all hdmi hookups. I pulled the back panel off but i dont know what i am looking for.

Re: 50" LG plasma . Vertical lines up and down screen.
Without a picture, it's hard to judge. However, it is possible the panel is bad, which would be uneconomical to fix.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

YSUS panel? Could it be a fuse ?Comment

I have a Thomas blasters multimeter 109, is there any way to check?Comment

Re: 50" LG plasma . Vertical lines up and down screen.
Plasma panel itself.
Y-sus and Z-sus can never cause vertical lines.
They are only responsible for making the whole screen light up.

Re: 50" LG plasma . Vertical lines up and down screen.
Do those lines move across the display occasionally?
How's it look like with a menu or video on the screen at the same time?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Possibly Y buffers.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

would this also cause the tv to turn off?Comment

Re: 50" LG plasma . Vertical lines up and down screen.
Y-buffers then.
I may have to retract Y-sus as "not being the cause"!
There is the possibility the Y-sus has damaged the buffer board.
Because of the cost of Y-sus and buffers it would most likely boil down to an IPM replacement plus replacement of up to 8 buffer ICs, which is not an easy job.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

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 doesnβt 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... -
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... -
Hi
Asking for a friend.
I'm used to black vertical line in otherwise good image - probable solution is a rubber to push and tighten the COFs bonding.
but here its the opposite !
TV has new T-con = same issue
A missing panel voltage would have global effect
So , what should one do ? how can I find where the fault is ?
Thanks !... -
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...
