How do you adjust the vertical lines going across my screen?

The vertical deflection circuit of your tv has a problem.
First, try to replace the vertical ic. This ic can be found near the plyback or horizontal section. It is a linear ic with heatsink.
If nothing happens after replacing the ic, replace all the polarized capacitor near the ic and resolder the components at the vertical section.

Panasonics will usually need the 2.2 ohm 2watt resistors replaced with the ICs , as usually at least one will blow possibly two when the ICs fail. If you didnt replace the resistors you will also most likely need to replace the ICs again as a bad resistor will ruin new ICs usually

Did you chane your ICs recently? If so did you replace the resistor near the ics? These resistors often fail and if you replace the convergence ICs without replacing them they will take out the new ICs quickly.

Convergence adjustments

did you use the proper STK IC's Do the replacement IC's have SANYO on the face of them? If they do not, this could be your problem. You must use the IC that the manufacturer recommends. All IC's are not alike. Go to MCM electronics and enter your IC number and they sell original SANYO IC's. Good Luck
