Hello, and sorry you're having problems. We are now connected on this website- which saves you money over having a Tech come to your home, and in many cases we can fix the problem you're having. In other cases, these things do require additional parts to fix. But I can help you with that as well.

What is the model number off of the back of the TV?

What exactly is the weird problem you're having (nothing is posted on here)?

It's a Samsung PN50C450B1D Plasma TV with a GREAT picture.
Customer: replied 1 year ago.
The weird thing is that it has started having these strange vertical lines intermittently after it's been on for a while. They are about two inches wide, sometimes black or white or both and sometimes with colored lines, sometimes only one line and not always in the same place. Sometimes, if it has colored lines, after a while it scrambles and goes away.

Hello, my name is ***** ***** I'll assist you. Previous expert has opted out. I'm sorry you're having trouble with it.
- Are you looking to repair the TV yourself (it needs basic electronics knowledge and experience) or want diagnosis and approx cost on repair info?

Please reply back to assist you accordingly.

Thanks.

Thanks for the info. I'm typing answer for you and it may take 10 minutes, is this OK?

Expert:  Shahid replied 1 year ago.

Please find attached image to view board locations inside TV where I marked Buffer E, Buffer F and Logic Control board, there are few flat ribbon cables plugged in logic control board coming from other boards, it needs to unplug flat ribbon cables safely then clean the contacts on cables (make sure the contacts/ lines don't get damaged) and replug them safely and properly to refresh the contacts as black/ colored lines appear due to bad contacts of these flat cables, however, some times logic control board or buffer boards also found bad (hardware failing issue) and need to be replaced to resolve the problem.

I trust my input will help you out. Please feel free to respond if you have any additional questions.
