    We recently experienced a horizontal line with no sound. Sometimes either tapping on the cabinet or powering off/on may temporarily resolve the issue. Now, we do not event get the horizontal line or sound. We hear audible clicking when initially powering on.

Hello e26pitts,

If the line is horizontal then it could be a problem in your vertical deflection section, if the line is vertical then the problem is in your horizontal deflection section. Now for a little more detail.

If Horizontal line is present the vertical section of the yoke transformer is nit responding to current flowing through it due to being open, or the vertical coupling capacitor is open, or even the vertical drive transistor might be defective.

If Vertical line is present the horizontal section of the yoke transformer might be bad. Now this gets kind is easy in a way, because the yoke would be the sole cause of your problem here (maybe there is some circuitry doing some horizontal coupling check that to) because the horizontal section controls other functions that would also respond if this were a horizontal drive issue. In any event these problems should be checked by a qualified TV technician, I would suggest that you take the TV to a repair shop to have it worked on.

I hope this helps
Thank you,
Shuttle83

Samsung TSL2793HF - Slight Right Side Pincushion and Horz Line Bottom to Top Until the TV Warms up


Yes, this is rare but I have seen it before--not fixable if it is what I think it is----It is what is called a Dome effect---the shadow mask in the picture tube is actually contracting and or expanding depending on temperature---

Directly behind the phosphor coating (the stripes that you see on the screen) is a metal screen--the holes or perforations in it line up with the stripes on the phosphor screen.

Some masks either have a material or a defect causing the dome effect----Not likely to be anything else---a Pin amp problem will not usually act the way you describe but a shadow mask inside the picture tube will act exactly that way.

White line screen


A white line left to right in the middle of the screen means you have a problem in the vertical circuit of the set--either bad solder connections or a bad output IC IN THAT CIRCUIT ARE POSSIBLE.

sounds like bad capacitor in vertical circuit. It's not a hard fix if you know where to look. Repair shop should not have hard time repairing it.

Green line in middle of tv when switched on


Is there a picture with the green line going through the centre. If it`s just a green line with no picture, it sounds like the Frame (Vertical scan) Output IC has failed and possibly the safety feed resistor near the LOPTX. The reason why it`s a green line is to protect the tube from phosphor damage. The older TV`s would produce a VERY bright white line across the screen which could burn the phosphors withing the tube if left turned on in that condition. It`s not an expensive repair, but is it worth it with the price of Modern TV`s nowadays. If there is a picture with a green line, it may be due to phosphor damage, in which case, it`s a new CRT (tube). Ian

Black box in middle of screen


It's a text box for either closed captioning or demonstration mode. Go into the setup menu and turn off closed captioning. If you have trouble doing that, then just restore factory settings.

White lines accross top of screen on our 27 inch Toshiba,


lcd or plasma.
are the lines solid or blurred. do they have sharp edges.
You may have a memory problem with the display which can only be repaired by factory trained technicians, or a brave soul willing to find parts on ebay.

Tv repair


You don't have to buy a new tv, it is a fairly simple problem, your vertical ic is blown, and it could be the powersupply to the vertical ic also. To verify, slightly increase the screen voltage, and a horizontal line will appear on the screen, if the voltages is okay, change the ic, but first try resoldering the ic pins. Good luck
