studio54, If the beam will not lock your problem is on the color convergence board. You can either replace it or contact a service shop tech to come out and take a look at your problem.

studio54, There should be a layout diagram in a pouch on the back cover. Locate the convergence board part number and post back with it. If no diagram in pouch you'll have to remove the bottom cover and look for a diagram inside the cabinet.

Sounds like the tuner is failing. The first thing i'd do is check the voltage sources at the power supply and at the tuner to make sure there not falling off due to cracked solder. If the solder joints are ok and the voltages are stable then replace the tuner.
