Vertical white stripe on tv screen

Hello,

I am trying to discover if there's a way to fix this white vertical line on my tv panel. Belongs to a Toshiba TV (40TL838) wich has a Samsung panel ref. LTA400HV01.

There are also some horizontal lines on top wich I wanted to solve too but the main pourpose for this is the large white line.

Thank you very much for your attention!

Kind Regards,

Daniel

TV has vertical colored lines on the screen. This is a common issue with many TVs. Vertical colored lines usually show on a TV screen when the T-Con board is not working properly. Many times this can simply be caused from wiring that is not securely fastened. Other times the T-Con Board itself may be faulty and need to be replaced.

Or

If you experience a TV showing colored vertical lines, try gently tapping in different areas on the back of the TV, you may see the vertical colored lines go away completely or they might decrease in intensity. If so, you may simply have a loose wiring cable. This is not a permanent solution, but may prevent the vertical colored lines from showing temporarily. To fix this permanently, you need to troubleshoot the issue and find out which wiring harness may be loose, faulty or damaged.

I changed the t-con already and unplugged all the wires, until now nothing..

I have the same issue. TV is only 3 years old so I am surprised to be having issues with it already...:(

intrestign this seems to be a commmon enough fault.. mine is the same but a segment more to the right that yours is.. if you leave it on a black screen it will fade away.. ironically, thats what happened to cause it on mine, it was left on a black screen for a few hours over night then the next powercycle it had this issue.. intresting.

Vertical white stripes are caused by water damage from a spill or condensation. You need to open the tv and dry it out with a hairdryer. Keeping your hands clear from anything electrical.

No... I bought a new T-con board and nothing changed. Last month I tooked it to a repair shop. Worst thing to do. They burnt the older t-con, the screen was all black with like a short-circuit, they also made some damage to the remote to say at the end that it's a panel problem, so, no solution.

I called to ask why the tv was delivered in worse condition than before and they replied that it can happen when trying to fix the panel ....?

Sometimes I wish I had born a suicide bomber, but at the same time, one explosion would not be enough...

I will keep searching for someone professional to solve this and if, someday I have the answer, I will post it here...
