SOURCE: 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!!!

SOURCE: The image is compressed into a thin vertical line

Sounds like the vertical IC has gone out. Possible with some capacitors. Usually, when you take the back off, Its located on the right side towards the front. It usually has about 10 legs. I can't remember off the top of my head.

How do I fix red vertical line on my crt t.v?

Horizontal scan out fault. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. Check the deflection yoke connector [connector pin to its socket at main board] for any loose solder terminal.

You haven't mentioned anything about your Sony TVs model number. Yet I'm answering to you, considering it as a general problem for Sony.
Your set's vertical output section has the trouble. Normally Sony uses a 9 pin Ic for this section for their 20 tvs, starting with LA' Series. This is a small IC vertically mounted on the circuit board,and screwed on to a heatsink plate. Just replace the capacitors around it first. Most of the electrolytic capacitors will go reduce in its capacitance value with time. Check the input voltage to that IC also. This input voltage is usually derived from the Line Output Transforemer's [LOT], secondary winding, and come upto 28VDC or so. If this voltage is very low, the retifier diode connected to the respective winding of the LOT may faulty. Replace it with same type and number.
When replacing electrolytic capacitors, keep a keen look on its polarity,as tthey ahve both positve and negative terminals, and should be coincide with the printed circuti board. otherwis it will burst off when supply is charged.
Replace all of them including the majn smoothing capacitor to the IC voltage. If these does not help, replace the vertical output IC. It will not cost too much. OK.

Vertical Hold circuit?

that is usaually a component in side the board called a capacitor that bursts due to high voltages passing thru it. so u will need a technician to replace it for you at a cost

Sony tv no picture only horizontal line

The probable defective part is the vertical IC. If changing that does not resolve the problem, check the capacitors in the same circuit. Also, check for the proper voltages at the vertical IC. If the IC is not being fed its power, it won't work either. I don't have a listing for your specific model. If you can post the vertical IC part number (LA7837 for example), I can list the voltages per pin.
