Thanks for the reply. The 42 in the model number indicates it is a 42" screen.
How long have you had the set for and when did the problem occur?
Was it after a storm or power outage?
Please disconnect the set from AC power, then press and hold the power button on the TV itself (not the remote), for 10 seconds. After another minute, plug the set back in and press power once. Do you still have the same problem?
Glad to hear it worked! This is common for all flat panel TV's (not just Westinghouse), and like a computer they simply need to be rebooted sometimes.
