Hi Roberta.

its the horizontal circuit fault in the Tv. Look back from the Yoke socket and from the two red and blue terminals and you you will get into the horizontal circuit

uusually its components starts with the number 4 at the Tv chassis

resold the components there good and this problem will be fixed

as its a solding loss or track cut at the tv chassis

you need to be familiar with tv repair to do this or get technician to fo thid for you

TV has a great picture but wont "hold it". Keeps going to a single flat horizontal line across the middle of the screen. Tapping on side of TV used to bring it back but now, nothing. Just a line.


Vertical scan output section circuit fault. Absence of vertical scan causes the single horizontal line on screen. Horizontal scan output section is OK. Contact any service technician to troubleshoot the vertical scan output section circuit. If you wish to get some details; check the site linked here.

My sony tv model no. kv-ha21m80 is on standby mode & its LED is blinking four times that means it has some problem in vertical section.But when I tried to check voltages of its vertical IC AN5522


Disconnect Vertical supply and so that your Horizontal system run check all voltages before connecting vertical again ...should the protection come in again when vertical connected ...replace Vertical Ic and safety resistor in line

Ive got a line down the left hand side of the screen when the tv is turned on the model number is panasonic viera tx-p42v20b


HI,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER

GOOD LUCK IN RECTIFYING THE FAULT, THANKS

DEAWOO TV Model no DTC 2975 vertical line i want to know that vertical ic number b,cos of that ic is burn & blast,i can't fine out.


If you have a bright vertical line down the screen you have an "S" correction fault. Usually there is a small choke that gets a dry joint under it.
Check for dry joints.

My tv is all blackexcept a wihite line through it and no sound


If the line is going across the TV the vertical deflection circuit needs repair. If its going from top to bottom the horizontal circuits are needing repair. Please post your model number and I will be better equiped to let you know which part is likely at fault.
