If you did not have vertical drive, changed the IC, and now you do but the screen is green with retrace, you probably had two separate problems. In many cases these kinds of problems are caused by bad solder connections. It would certainly make sense. First I would resolder all connections on all boards (or at least all suspicious looking ones) and see what happens. If you're lucky this will solve your problem. Good luck.

Have you vertical deflection circuit checked for bad Vertical IC, and or Bad vertical Capacitors in the vert output section for the deflection board. Also have Vertical output Pump up Capacitor replaced, also have B+ voltage check coming from flyback transformer, for any open fusible resistors

No video on my JVC AV-30W475 30" flat screen.

It sounds like you have bad solder connections in the Vertical circuit or the horizontal circuit. The Vertical IC may need to be replaced if resoldering does not help.
You will need to call a good TV Tech for this repair.

Sanyo DS27880 TV, vertical sweep is gone, sound ok

Check for cold joints on the vertical chip. DS27880 sets use a la7841 typically.

If soldering doesn't fix it, simply replace the vertical as well as the 1ohm 1/2W resistor and
the fast recovery general purpose (nte556 equiv) near the flyback.

Flickering multi-colored line in the middle of the screen.

You have a failure in the vertical deflection circuit. This could be either a bad vertical chip, the power supply that runs the chip or a bad capacitor in that circuit. This is usually a repair best left to a professional. There is a small possibility that it could be bad solder connections. If genlty tapping the unit temporarily solves the issue you can try and resolder the pins on the vertical chip LA7841 is the part number. There is also a resistor 1 ohm 1 watt. If that resistor is open you can assume the IC is bad

No vertical sweep on my Sanyo DS31590

This is a fault in the vertical circuit. It can be either a bad solder connection of the vertical IC or a defective IC. If you can solder, you can fix this yourself. Open up the back and locate teh vertical IC. It willbe a small flat IC attached to a heat sink and be marked LA7841. Resolder the pins first. If that fails to resolve the problem, replace the IC. Please note that there may be capacitors in the circuit that need to be changes as well, but without the chip working, it will be difficult to determine which ones. Update this once the IC has been resoldered or replaced with the results and we'll continue if necessary.

Sanyo DS31590 31" TV vertical deflection

If the vertical is not defective or shorted there is a possiblity of bad solder connections on the vertical ic. If connections are good and has b+ voltage to the chip replace chip which is IC 501 LA7841 or LA7845 and change c511 (decimal point 1 film capacitor)

Sanyo TV model DS25710 or DS25730

Set has a bad vertical sweep IC. Also This Sanyo has a tendancy , when the IC blows out , to take the fusable resistor in the sweeo supply that feeds the vertical IC. This set should only be serviced by a trained technician because of ther high Voltage that lingers within. This repair should run you antwhere from 85.00 to 150 bucks. Good Luck
