Hi my LG 47ln5700 tv set has thin greyish black horizontal lineson one side of the .... I hope this works good with Samsung LCD as well....
Sounds like the CRT tubes are going out which is fairly common on Sony. Inside the back of the TV there are 6 knobs - 2 for each color...one is for focus - dont touch - the other for brightness...turn down the brightness just a hair untill the lines go away.
a bright thin line in centre is called horizontal line.
first of all do not keep tv on unless it is rectified.
BUT
If you want to put on tv keep brightness minimum to protect your screen for any demage.
now solution
your problem is in vertical section.
1 check vertical supply.
2 check parts in vertical section or loose contact.
3 yoke connrctor loose
4 ic defective
It is not serious problem can be rectified easily
this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!
sound like the screen control on the flyback is set just a little too high. the flyback has the red wire attached to the tube. the flyback has 2 small adjustable controls. if you look close enough 1 is marked focus & on is screen. turn the screen slightly to the left & look at your picture. the screen is like a master brightness & if it's up too high you will see what is called retrace lines.
good luck.
i have panasonic sophia tv 29" i have white horizontal line on middle of screen i know i have to solder ic but where is the ic located on main circuit board. thankx
