CRT TV with a white line half way up the screen

You hereby reports that the one side of the screen do not display picture, and the other side have. Is it seen vertically or horizontally. Will you please provide a detailed description of the fault you see on screen? google.com/+GopakumarGopalan

Hello
Check the smoothing capacitor to video output supply voltage, usually derived from any one winding of the LOT. It will come around 10uF350VDC to 47uF 350VDC range. If this capacitor is faulty, or gone less in capacitance with time, this type of fault will occur. Check the green volour output transistor on the video output card, can be located attached to the neck of the picture tube; for any loose soldering or leakage. OK.

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.

Lines means Screen Drive is overdriving, try adjusting the Screen control on the FBT flyback Transfomer, adjust it down. If that does not Clear out Problem then replace the CRT Board that is connected to Picture Tube.

U can't.Only horizontal lines on the top parts of the tv screen or the lower parts of the picture screen.Or very light horizontal lines mix in with the tv screen pictures.The "CRT" the picture tube is slowly dying of old age.Quicker than they supose to.The late 90" these problems case show up alot more in standard tvs using CRT tube.Because the CRT and analog design about to be faze out of the market place.The glass molding and those radiation matrials,they used to make those "CRT" picture tube materials,not as good as before.

sounds like a vertical problem, usually you'll see one white line across the screen, but one I worked on would come on and the bottom half of the picture was gone and there were lines across the top of the screen.

If you know how to solder & can find the vertical output chip then you could try resoldering the pins. If this doesn't fix it then it needs new parts.

this is a frame fault
the fact that you can still see the line when the tv is off is because you have been watching with the line and it has burnt into the crt.

time to buy a new tv

the problem of your tv is in vertical section, to be sure change all the capacitor in vertical section.

The half picture is a verticale problem. This is difficult to repair. Send to a repair shop.

Resolder vertical IC. (loose connections!!!), Ready!!!
