The problem is in your deflection coil, the other half had been shorted probably.

Tv 27" has only half screen picture horizional I


Possible failure of the VERTICAL SECTION of the deflection circuit. It is possible that the areas related to the vertical circuit is checked , check for weak capacitors near the output vertical drive. Also a faulty vertical coil- deflection coil- can result in half picture.
A vertical signal test can confirm.

I HAVE A HALF SCREEN. BOTTOM HALF LOOKS GOOD TOP HALF HAS WHITE LINES WITH A BIGGER WHITE LINE SEPARATING THE TWO. IS THE PICTURE TUBE GONE OR IS THERE AN ADJUSTMENT I CAN MAKE? TV IS A RCA F25645


This is commonly known as a vertical deflection problem. It cannot be fixed with an adjustment, but requires changing some electronic components. Namely the vertical output IC (integrated circuit) and in addition usually in this model a resistor which may appear to be burned.

Hi I have a sharp 27H S60, has worked fine for many years. Now, I get fine sound but no picture. When it is first turned on I get a thick white line in the center of the screen for a second, then it is...


The problem is a vertical deflection issue, it means the picture from top to bottom has collapsed. The set will require two or three capacitors and an ic and it is quite fixable.

The top half of my screen is black, the bottom half shows the "top half" of the picutre.


Hi there.
It sounds like a vertical problem. And by the description you`ve given it might be caused by bad capacitors in the vertical deflection circuit.
Hope this help Merry Christmas

1/2 of picture is ok; the other one only lines. What is?


If it's the top half that's lines and the bottom is ok, it's a problem in the vertical deflection circuit. Probably a dried out electrolytic capacitor.

If it's left to right, that gets more complicated. Please provide more info.

Half screen picture


This is commonly caused by failing capacitors in the vertical deflection amp area and sometimes with the output drive devices.

An experienced TV tech can troubleshoot your set and service it for you.

Picture on Panasonic tv intermittently becomes striated and bottom half of picture shows on top half of screen


Hello! What you're describing sounds like a vertical deflection problem if it also occurs when you're watching a TV program. This type of trouble is a component failing in the vertical circuit of your set. A loose solder connection could cause this. On the other hand, if it just happens when you run the VCR, your problem could be somewhere in the tape drive mechanism or possibly a bad tape. Things like slipping clutches,bad belts sticking guide rollers are a few things that will cause this in a VCR. You need to have a tech check it for you. Hope this gives you some help. Stargazer
