Vertical scan section circuit fault. Check and replace damaged component/s at its vertical scan output section circuit. If you wish to get some details, check the site linked here.

It needs repair. If the line is vertical, then something is damaged on its horizontal circuit section on the mainboard. If the line is horizontal, the vertical circuit section is damaged. have it repaired to a qualified service center or person! avoid switching it to avoid further damage on other parts!
this is a common problem,the vertical hold has been damaged.dont leave the teli. on,the white line will burn the middle of the screen and leave a black mark. You need a new integrated circuit(i.c.) for vertical hold.
keep tv off.
it will only get wors
if sumon dosent work on it soon
the problem you are having in the vertical section of the tv
hav a repairman resolider all conection on the vertical IC and check the serounding componets for falts.
PS the repair takes me about 15 min.
hi there, is the single line horizontally or vertically? if horizontal line, you do have a vertical section problem, check some parts at vertical section, the vertical ic, the power source of vertical section ie diode & resistors. ty
My LG tv has suddenly got a problem with the picture. Whilst watching the tv with no problems at all,
the picture was suddenly reduced to a thin vertical line down the centre of the screen
and an awful smell seemed to come from the tv
There is a short ckt in your tv in horl. section.
1 isolate power from horizontal section.
2 check for normal output from power supply.
3 check parts in horl output section
a hor.output transistor
b diode & cap in h/output trnsformerckt.
c check for print.
d if all are ok check for eht transformer.
e if every thing becomes then reconnect hor output section supply.
f put on the set.
The vertical output IC or the vertical circuit is whats at fault. its all solid state and im sorry to tell ya that its not a user replaceable part. This set is probably not worth the repair it would take to get this set working again but please if you like ask a ;ocal repair shop what they thought about this problem..
