If you own a Samsung plasma TV, you may have encountered the problem of a black line appearing on the screen. This issue is common among plasma TVs, especially those that have been in use for over a decade. The good news is that it is not a component problem, and fixing it is quite simple. In this guide, we will show you how to fix the black line on your Samsung plasma TV.

First, let’s take a look at the fault. The black bar usually appears at the top of the TV screen as a couple of lines before it becomes a bar. If you tap the screen, the black line may get bigger. This indicates that the problem is likely a tap issue. To fix it, you will need to take down the TV and identify the root cause of the problem.

Before you start, keep in mind that plasma TVs are heavy and may require some assistance to remove from the wall. In this case, we have a 63-inch plasma TV that weighs around 150 pounds. Once you have removed the TV from the wall, take a look at the back of the TV.

The TV has several boards, including the power supply board, the main controller board, and the sustain board. The y-sustain board and the buffer boards are the ones we are interested in. The problem is likely a loose connector on one of these boards.

Start by tightening all the grounding screws to ensure that they are not loose. Over time, the screws can work their way loose due to repeated heating and cooling. Next, reseat all the connectors to make sure that they are securely attached. You can easily detach the tap connectors and reattach them.

After tightening all the screws and reattaching the connectors, power up the TV to see if the problem is solved. If the black line disappears, then you have fixed the problem. In some cases, every one of the four grounds may be loose, so make sure to tighten all the screws on all the boards.

If you don’t see any capacitors that are bulging, then the power supply is not the issue. Samsung had some power supply issues on their earlier TVs, but this is not the case for this TV. The caps are all good, and there is no sign of bulging.

In conclusion, if you have a Samsung plasma TV with a black line on the screen, don’t worry, it is a common problem that is easy to fix. Simply identify the loose connector, tighten the screws, and reseat the connectors. Your TV should be good to go for another decade.
