The control panel, or the circuit area that reads the control panel, or the uPC is not functioning properly for reading the control command. The service tech will try a new control panel assembly, or the module(s) that have the related circuitry. Once the defective modules are replaced, the tech will leave in the new modules.
When under warranty and these sets are exchanged under warranty, they give you back a set that was serviced from someone else. That is the drawback with having the set serviced under warranty.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
