Try resetting the TV by unplugging from wall outlet for 3 to5 minutes then plug back in. If no fixya take front grill off and panel and adjust the screen controls, turn color off adjust for Black & White Picture. Good Luck, big IRISH.
You dont have to remove the aluminum heat sink. The ICs are attached with screws and then just unsolder the ICs from the circuit board and then replace the new ics into the pin hole locations after applying heat sink compound onto the back then screww the new ICs to the heat sinks then solder the pins. Very easy repair.

Most likely cause would be a loose solder connection that expands as the set warms up until it no longer makes a connection. You may get the blue to come and go by hitting the side of the cabinet after the set is warmed up awhile. (don't hurt your hand doing this, and don't keep doing it to "fix" the set. The connection will have to be located and repaired). Otherwise, there could be a component going bad, including the blue picture tube.
