55 inch Samsung screen
(Figure 1) Vertical stripes appear in the image on the screen
(Figure 2) After booting up, the screen displays a vertical tape (Figure 2).
Analysis shows that this fault phenomenon is due to the power supply problem
of the corresponding vertical tape TAB from the edge board. Through observation,
it was found that there was corrosion and wire breakage at the connection between
the corresponding vertical tape TAB and the edge board (Figure 3),
Use a blade to scrape off the corroded copper foil on the edge plate, then remove
the TAB plastic from the corroded area and scrape off the copper foil. Connect the
corresponding flying wire that was broken due to corrosion to the flying wire and
fix it with glue. The power on screen displays normally (Figure 4)
The vertical belt fault has been resolved.
