Call Panasonic National Parts and request a price on the service manual of your TV which I beleive it shouldn't more than $ 50.00.
In that manual you will find any type of allignments and oscilloscope waveforms your hart desires, like service codes for accessing service modes, crosshair allignment, purity allignment, convergence allignment geomtry allignment, sound allignment and so on.........
