For the image problem the first thing to do is replace your ICs

For simple instructions on how to do this, see the following link which basically applies to all tvs
http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm

Try replacing the ICs first and then we can work on the Menu problem

Is there any reason that you may have started to have these problems?

    Did this menu problem start happening at the same time? You will also have to look at the connections on the board to make sure everything looks fine

Your set uses the 195 series chassis, which has separate components for each of the 6 convergence channels and a separate power supply for the convergence circuits. If all 3 colors have drastically shifted, especially around the edges, then chances are your convergence power supply has stopped working. This is usually caused by the failure of the STK730-010 switching IC. If one of the colors has dramatically shifted by itself then something has stopped working on the convergence board. Sometimes I see CRT coolant leaking onto the convergence board as the cause. In either case this is something that should be repaired and realigned by someone experienced with RCA projection TV convergence circuits.
