My tv sony kv-xa21m61 display too bright and many horizontal lines. no picture


Vertical retrace lines is the problem. Thin white lines runs across the entire screen, at about an inch apart to each other. Check its video output supply voltage. Reduce the screen voltage to a little bit down and check. If you still wish to know more about this fault, check this site. Pull up older posts there.

White lines on the screen.sounds ok.picture is coming behind white line.


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.

if the set has a previous vertical line problem and a white horizental line only comes in the cross of the screen and you turned the tv on for a time while the problem is solved that mean you have make a burnt line to the screen , but if you are the tv owner and nothing of that happens so you have a problem in faulty dried capaciter in the vertical live part search for 33uf 160 v or 22u 160 v and alter regards please don't forget to rate thx

SONY KV-27FV310: UPPER HALF OF SCREEN IS BLACK


You have a vert sweep problem and unless you know how to trouble shoot this cuircit bring it to a pro. I found out mostly in these sets that the vert output IC is bad.. Also sometimes the b+ filter cap off the fly is leaky and made the IC to fail. Another thing is Im surprised to hear you got a pic with the vert failure and a bright line in the pic!! This could be a big problem when the sets fixed so dont run it too long like this. It could burn a line all the way across the screen and you will see a dark faint line in your pic because of this. BE CAREFULL!!
