IF your TV is not one of the real old ones, you have a problem with the automatic tuning system. Some component in this circuit most likely a capacitor or coil is changing its electrical properties due to temperature which in turn causes the set to be off frequency until it warms up. A capacitor (condenser) can do this quite often. Stargazer
