My Sony tech says it's most likely a bad cable box. Try a DVD and if the DVD is fine then it's for sure your cable box. Needs to be replaced by the cable company.

The processor of the tv locks up because it suddenly becomes incapable of correctly processing the signal data - it crashes.
Since this is an intermittent problem that appears when a big spike in power is required from the source that means that the problem is caused by a dip in the voltage powering the processor - the power source has aged and it's no longer capable of delivering a steady supply.
You must open the tv, locate the power source and refurbish it: start by replacing all capacitors, then check the rectifiers, then the zenner diodes and finally the stabilizers.

Did you checked tv picture by playing back dvd player?
Is tv connected with cable box, if yes, is it HDMI connection setup?
Let me know above info to diagnose cause of problem.
