SOURCE: thin horizontal line

Defective components in vertical deflection and output circuit inclusive of vertical output device, coupling capacitors, and yoke connectors. Passive devices such as electrolytic capacitors, coils, and resistors to/from power supply circuits. If your tele is more than 10 years old dump it and get a newer product. $100 USD is a fair price to diagnose and attempt service, depending on age and configuration. Older products may not have replacment parts available at any repair cost. There may be a pot for adjusting the vertical size. If so, it may be dirty. If you can find it, try adjusting it which could clean it. BE CAREFUL -voltages are very high.

SOURCE: Picture goes to one thin horizontal line in middle of screen

There is a bad solder connection in the vertical sweep circuit. if you know how toi solder, go and find the vertical output IC and resolder that first.. but if you have no solid state electronic repair experience, please find a trained tech to assist you in this repair, as if you wait it may end up costing you double of what it would now, so haveit done ASAP. Good Luck Please do not forget to rate this one.

SOURCE: Tv not working

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!

SOURCE: only thin white line across my toshiba tv

This is an easy repair if you've ever soldered and would not be too costly for a repair shop to do it for you. The problem is a bad Vertical Output IC (usually mounted on an aluminum heat sink with the part on it labeled LA78?? ) and 1 or 2 bad capacitors. Some times you can even fix the problem by re-soldering the contacts of the IC- To find the IC follow the 4 wires that come from the Yoke (which is a contained coil of wires slipped over the neck of the picture tube(s)) back to the board. 2 of the wires go to the horizontal o/p and 2 to the Vertical o/p the thinner gauge wires are for the vertical.

TV has a great picture but wont "hold it". Keeps going to a single flat horizontal line across the middle of the screen. Tapping on side of TV used to bring it back but now, nothing. Just a line.


Vertical scan output section circuit fault. Absence of vertical scan causes the single horizontal line on screen. Horizontal scan output section is OK. Contact any service technician to troubleshoot the vertical scan output section circuit. If you wish to get some details; check the site linked here. Pull up older posts.Surf the site with patience.http://electronicshelponline.blogspot.com/
Horizontal line fault to CRT based TVs are given.

Sanyo flat screen tv about 2 yrs old has thin colored horizontal lines down the right side


Nothing you can do about that...get used to it or change the TV.
It's a defect in the panel that can't be reliably fixed.

We have perfect sound but only a thin horizontal line in the middle of the screen.


this is a capacitor that has gone bad in the vertical delfection stage of the tv. it is an very easy and cheap fix if you know someone who knows how to solder and replace electronic components. If not then you'll just have to get another tv as taking it into a tv repair shop is not worth the cost. You could get another tv for what they will charge you to repair it,

The vertical output IC LA7847 is failing. It will likely fail permanately and you will have just the horizontal line. The set will require service. Just do not run the set very long in this state. That thin white line can likely burn into the crt phospher and will show all the time thus ruining the glass picture tube...
