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.

Screen is half picture and half black with vertical colored lines


I had the same issue. I could get the tv to work intermittantly by pressing on the boards while playing. This points to bad solder joint, so I resoldered every molex plug connector, and it nows works like a charm.

CRT TV with a white line half way up the screen


Hello,

The white line is result of a Vertical failure. Believe it or not, the whole picture is contained in that one white line, but it is not spread out from top to bottom on the screen.

Usually, a vertical failure is IC or capacitor related. Should be an easy, fairly inexpensive fix for a competent repair shop.

Hope this helps you...

Hello bouloulou, Well let me tell you what you have is a loss of Vertical Linearity. This could be cause by a power supply issue or by inproper filtering of the dc voltage used to supply the vertical section of the TV. There used to be a control which allowed you to adjust this along with Vertical Size which controled the bottom of the screen. These days the signal processor chip takes care of this along with a few capacitors. I woould suggest that if you do not have a background in electronics that you take the set to a shop for repairs, If you do have a background in electronics, get a schematic for this set and the use your multimeter set to DC volts to measure the DC levels in the vertical section of the TV. Also you will need an oscilloscope to measure the ripple voltage on the DC power supply the schematic will show you how much ripple is allowed. I hope this helps. Thank you, Shuttle83
