Horizontal white lines 27A43.


You have some bad capacitors. They are located very near and next to your vertical IC. I would guess you would have to replace maybe four of these! Thanks for asking!

I turned it on and just one line accross the screen appears. the audio is fine.Everything is normal except theres just a line on the screen.


You have a vertical problem. You may need to resolder the vertical IC, and check each cpacitor that is near the vertical IC. Your TV will be restored to full screen!

No picture. Just a vertical line accross the screen.


When this kind of set comes in for this problem, it is typically caused by a leaky/intermittent diode D402, located next to the heat sink for the vertical deflection IC. I will typically also replace the vertical deflection IC at the same time, just to avoid repeat failures.

White line horizontially through middle of picture


A repair like this is in the vertical drive/output section of the TV set. It could be a simple capacitor causeing this problem or a combination of the capacitor and the output IC. A repair like this should not exceed 120 to 150 US. Is it worth that to you? How much can you replace it for? Good Luck PS please dont forget to rate this thread.

No vertical sweep


You might be able to take care of it yourself,you are corret when you said no vertical sweep,if you can identify the vertical IC it will be easy,you are looking for loose conections but by now it might have a bad vertical Ic and it needs to be replaced along with the safety resistor that power the IC,the ic should be mounted on a heat sink and the resistor should have low resistance,very straight forward repair and while you are there make sure and check for overheated areas and loose conections specially in the power supply , horizontal drive circuit and convergence IC's.Be careful you still have high voltage witch can be dangerous.
