Horizontal lines accross the top of my TV they turn everything upside down when you look up on a video game like mountains and things and make normal Television fuzzy


the problem is in the Vertical circuit of the set, fold over and/or retrace lines at the top.

Problem will be either a bad vertical output IC or caps around it that are bad.

Unless you know how to solder and what to look for it will be a shop repair, if it is continued to be used this way sooner or later it will go to just a white line left to right in the middle of the screen.

Let me know if you need more information.

I looked up how to fix red horizontal lines on a Philips flat-screen tv. It turns out it needed the Y buffer upper replaced. I am not sure if this problem would be similar but it might help. I am also searching how to fix a fuzzy screen on a DLP tv. Hope you find what you need.

Laptop with Fuzzy Screen


It sounds like your video card is overheating.

Try getting one of the laptop coolers from bestbuy or other store. They separate the laptop from the table, allowing more air to flow and cool it. The good ones even have a fan to help it.

Good luck!

Tv not showing a picture


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,
