I am using the Harwa tv MODEL NO:HW-2120 It makes a horizontal line on a screen so what is the name of the vertical IC

Hi Majid
Just contact any service technician to repair your TV. It will be best for you.

Vertical scan output section circuit fault.
Check and replace the damaged component/s at its main board. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

hi if only a horizontal line across with no video anymore, you have bad either vertical ic or no dc supply b+( vertical ic ) or no output dc coming from the ic. if it is not totally a horizontal white line and you can see a video you must check leak or bulged capacitors at the vertical section near the vertical ic. hope this can help good luck.

Hello
You haven't specifed nothing about the model number or brand name of your flat panel teleivison. i assumes that it to be a picture tube based one and posts this solution before you.
A thin horizontal line across the screen with sound output is OK, is the sympton of total failure of vertical sweep. This may be due to failure of vertical output IC or loose solder terminals of that IC. The vertical output IC will heat up while working, and repeated heating and cooling may make its solder terminals to get loose. Just open your TV, pull out the board that contains vertcial output section, turn it upside down, resolder all the solder terminals of that IC by applying a little more solder, without making any solder bridge in between terminals. Check the voltage to the vertical output IC also. If this resoldering method does not help you, replace the vertical IC itself with same type and number will solve your TVs problem. OK.

Your vertical IC may need resolder. You may have a bad capacitor or two that created an extra warm IC and create bad grounds. So resolder and check those caps near and around your vertical IC. If you continue to see this horizontal line you may have to replace the vertical IC. And you may as well check all grounds as well. Good Luck and be careful!

Hiii fairley,

You aren't specsificly dercribe yor tv set.
For common TV horizontal problem ;i.e : White line accross the horizontal screen, horizontal band,etc..it's can solved by replacing the IC Vertical/Transistor, and olso to replace the cap nearest the IC.

For common TV Vertical Problem :i.e : White line at the center of the screen (top to bottom),Vertical band,etc...It's can cure by Replacing the Horizontal IC/Transistor,and offcurse the cap's.

Tha's what all I know....

Hope can help you to solved the problem.

Thank's

Check for the cracked solder joints on the IC or dried capacitors on the vertical side

Horizontal line shows problem in Vertical Deflection area of TV, please check Vertical Output IC and its voltage supply. You didn't mention model and brand name so I gave you general information for that problem.

1. solder the vertical ic first. otherwise replaced the vertical ic.

2. solder the yoke wires.

3. replaced the vertical ic supply capacitor.

hi there, is the single line horizontally or vertically? if horizontal line, you do have a vertical section problem, check some parts at vertical section, the vertical ic, the power source of vertical section ie diode & resistors. ty
