LED – LCD TVs - tcon and panel troubleshooting procedure

Symptom: there are vertical lines in the top right part of the screen.
Solution: the lvds cable can cause this symptom if it is not seated correctly. check the position of the lvds cable and the contacts. if it is seated correctly and you still see vertical lines, replace the lvds cable.
Model: lcd, led
symptom: there are two red vertical bars and red smears around objects.
Solution: the lvds cable can cause this if it is not seated correctly. check the position of the lvds cable and the contacts. if it is seated correctly and you still see red bars and smears, replace the lvds cable.
Model: lcd,led
symptom: there are horizontal black and white bars across the screen in rf only
Solution: as you can see, the osd is not affected. that tells you that the panel is ok. replace the main board.
Model: un55c8000xfxza
symptom: the right side of the screen is darker than the left.
Solution: bring up the test picture. if the symptom affects the test picture, replace the panel.
Model: lcd, led
symptom: there are vertical lines in the picture.
Solution: the lvds cable can cause this symptom if it is not seated correctly. check the position of the lvds cable and the contacts. if it is seated correctly and you still see vertical lines, replace the lvds cable.
Model: pn42c430a1dxza
symptom: the picture has blemishes.
Solution: if the symptom affects the test picture, replace the panel.
Model: lnt5271
symptom: the right side of the screen has horizontal lines.
Solution: in the example above, the line distortion is affecting the menu. bring up the osd menu. if the symptom affects the menu, replace the t-con board.
Model: un46d6500vfxza
symptom: ghosting image (double image)
Solution: replace the t-con and lvds.
Model: ln55c650
symptom: colored vertical lines
Solution: bring up the “picture test”. if the lines appear in the picture test, the cause is a bad panel. if the lines do not appear, disconnect all signal sources and check again. if the lines are still in the picture test, change the main board. if the lines are gone, then a signal
source is causing the problem.
