LCD TVs sometimes have problems such as horizontal and vertical lines on the screen due to their delicate structure and complex technology used in their panel. These lines not only cause a decrease in image quality, but also indicate a problem in the sensitive parts of the device. At such times, many people living in Karaj, Fardis, Gohardasht, Golshahr and Mehrovila are looking for a reliable center to fix horizontal and vertical lines in LCD TVs in Karaj and Alborz. The purpose of this article is to investigate the cause of lines, diagnosis method, repair solutions and introduce the best specialized center, i.e. Service-tv.ir to solve this problem.

The main reasons for creating horizontal and vertical lines in LCD TV

The creation of lines on the TV screen has various reasons, some of which are simple and some of which require specialized repair. The most important ones are:

1. Image flat failure

Flats are the interface between the TV panel and the main board. Horizontal or vertical lines appear permanently or intermittently on the screen if they are damaged by heat, shock or moisture. This type of failure is very common in Samsung and LG LCD models and is considered one of the most frequent cases of fixing horizontal and vertical lines in LCD TVs in Karaj.

2. Defect in T-con board

The T-con board is responsible for processing the image signal and transferring it to the screen. If there is a connection or capacitor problem for this board, colored or blurred lines can be seen on the screen. Specialized experts, such as service-TV repairmen, check this board with voltage testing devices and repair or replace it in case of failure.

3. Power fluctuations and damage to the panel

Electricity fluctuations are very common in different areas of Alborz province, especially Mehrshahr and Azimieh. These fluctuations may damage the delicate circuits of the TV panel and cause permanent lines to appear. Using a suitable electrical protector and immediate repair by experts is the best way to prevent further damage to the panel.

4. Failure in input cables and internal connections

When the HDMI or AV cable is not connected well, dotted or thin lines may appear on the picture. This is especially common in older LCD TVs and can be fixed with a simple service.

Signs of failure related to lines

If you see any of the following symptoms on your TV, the device probably needs horizontal and vertical lines fixed:

• Fixed and colored lines from the top to the bottom of the screen
• Shaking or removing half of the image
• Cutting and joining the image with colored lines
• Showing shadows or halos around objects in the image
• Color change and slight breakage in the display of pixels

If you see these symptoms in Karaj or Alborz, it is enough to contact the specialized TV repair center, i.e. Service-tv.ir so that the experts will come to your place.

Why should the repair of TV lines be done on time?

Many users think that the presence of a few lines on the image is a minor problem, but the fact is that if the failure is not fixed soon, the possibility of the panel or board being completely burnt increases.

Timely repair saves money because if the flat or T-con problem is fixed at the beginning, there will be no need to replace the expensive panel.

In the Service-TV series, after a detailed investigation, the experts announce the main reason for the lines and inform the customer of the exact cost before any repair.
