There is a blue gun but no yellow gun -- that colour is from combining other colours. If convergence isn't the problem I'd check for input signal problems. Ghosting can come from the multiple signals being received (one image direct from the transmitter, second signal received a split-second later 'bounced' off a skyscraper). Check the antenna input with another "known good" TV -- could be the coax is damaged.
