Vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch

JVC AV-27730: horizontal bright line across screen in the


it could be an electrolytic capacitor or the vertical output I.C. in the vertical circuitry,if you remove the rear cover tap on the board in different places and see if the picture fills out or atleast jitters like it might fill out,then it could be just a cold solder joint,then remove the main board and resolder all joints and this should repair the condition you have

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.

Bright horizontal line across black tv screen


Hi There,
If your picture has collapsed to just a horizontal line across the center of the screen, this indicates that your Vertical Output circuit is bad and needs to be serviced by a qualified technician. I hope this helps and thank you for using FixYa!

White horizontal, zig-zagging lines


It sounds to me like you're describing the re-trace of the unit. It is repairable, and more so the sooner you get it to the repair facility.

A bright line on the screen


A line running across the screen like that and then returning to a picture I would guess is the vertical IC has some poor solder joints. The vertical IC in that unit IC401 is an LA78041 a seven pin IC that is mounted to a metal heat sink. On the foil or under side of the board take a careful look at the pins of that IC and any that look suspicious carefully re-flow some solder over.. Careful not to keep your iron on the pin too long.. And if have to re-solder several take some time between them to allow the IC to cool so you don't damage it.. Good Luck Bill

Tv not working


this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!
