There is a line on the X65 TV screen of LeTV TV Maintenance Station in Rongchang District, Chongqing. What's the problem?

This kind of fault is generally called bright line,

The bright line is caused by the impact on the edge of the screen and the loose connection of the flat cable inside the LCD panel. This is difficult to handle. Disassemble the TV and squeeze the bright wire with your fingers. If the extrusion of bright wires disappears, remove the iron frame of the lock screen and insert some fillers to fix it. But if it doesn't work, it can only be operated by professional maintenance personnel, otherwise it will easily break down!
