Vertical line in center

Line, faults & possible causes to TV screen are given with illustrations. You can get an idea about the fault to an extent.

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. http://electronicshelponline.blogspot.com/ Check the deflection yoke connector [connector pin to its socket at main board] for any loose solder terminal.

hi..hope this help you....a horizontal line in the center is an indication of defective vertical IC...its looks like a tab w/ 10-12 pins and has heatsink...your TV would works out fine when you replace the IC....but its better if let a technician replace this....pls. don't forget to rate and vote....thanks...

This is a common problem with the vertical output IC and vertical section. (if the line is from left to right in the center of the screen)
Most shops will repair ths problem for under $100

It happens when Vertical deflection stops as Vertical Out IC becomes hot or does not get vertical signal.
Please check electrolytic capacitors and dry solder joints in vertical out section in TV.

vertical ic fult or vertical section supplys missing

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!!!

Sanyo makes a fine TV. You have a problem in the vertical circuit causing the line. You should not play the set in that condition because you can dammage the picture tube. Call a few local shops to get an idea of what they charge to fix a vertical problem on a 20" TV. If the cost of repair exceeds about 65% of replacement, toss it. In my opinion the newer sets are lacking in quality compared to older ones. In short , they break more often. If you choose to buy a new TV stay with a known Japanese brand.

Plug it in.

It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
