The side I took off was clear of the lines but the side still connected had the lines. And vise versa when the other side was removed the same thing happened just different sides.Comment

yes strip the set down sell or keep the parts even the ccfl tubes come in handy at times people will even buy the stands etc.Comment

What are ccfl tubes? How do I know the internal are working? Can I feel good about selling on Ebay?Comment

Re: LG 37lg30-ud Screen Has only vertical lines of color?
there the tubes that work the backlight that are behind the lcd screen etc.
regarding the boards you can defently sell the psu and invertor board as there working fine the t con and mainboard unless tested in a working tv are harder too test properly.Comment

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... -
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...
