No vertical output, but vertical ic workng fine,vertical supply ok,

Touch the input pin of the vertical IC, by the blade of the screwdriver, and see whether there is a tendency to change with width of the horizontal line on screen. If so, check and replace the horizontal, video if, vertical oscillator jungle IC. Check the frequency to the input of the vertical scan IC, with a frequency meter. If there is frequency, and still no vertical scan output, check the yoke connection, and make sure that it has no open circuit. If you wish to get some details, Pull up older posts.

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

When i turn it on the screen has lines in it and it shuts off

That symptom is called vertical problem.The problem is located at the vertical section of your television.Maybe there's a leak capacitor around the vertical ic,or loose connection of vertical ic.or no B+ supply in vertical ic,and finaly the vertical output ic is deffective maybe it is shorted that why the power shutoff. So its the cause of the problem and need to repiar by the repair technician.Thanks...

Vertical line in center have replaced vertical output ic

If the line is vertical then the problem is no horizontal deflection. The vertical chip is probably fine.

Check connections around yoke (thats the connector with at least four wires that goes up to the coils around the neck of the tube)

Maybe that TV has two horizontal output transistors. One for deflection and one for high voltage? Check both of them. Look for bad solder joints!!!

Vertical line in center

If the line is "vertical" then the vertical circuit sounds OK. The problem would be in the horizontal deflection.

Check yoke connection and solder around horz defl circuit.

If the line is horizontal then I would suspect the vertical IC.

Vertical deflection went out and now HV is going into shutdown

Get service manual / schematics from HERE and find why vertical uotput IC is blown in your TV.
Service Manual will also give you info how to perform vertical adjustments.
Hope this info will help you to resolve problem.

Screen only showing single line of video in center.

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

Veltical is not open wade the hole peature

if it is not showing whole vertically means your problem is in vertical output section.

  • any capacitor or low value resistor failure in vertical output section
  • loose contact in vertical output section
  • vertical output ic failure.
  • hope this will help
