It has no sound, channel do not change with remote control. Try to reset a few times but no avail. Is it power supply board defect?
Hello Yong, for what you say, your Westinghouse DW50F1Y1, would need a firmware update, look at www.westinghouse.com for the updates available for your model and the downloads in an empty USB memory, without any file and then place it in the TV and update the Firmware

The most common failure are the two convergence integrated circuits part # 267P173010. The two pico fuses may be open as well, which come from the power supply and provide +24 volts and -24 volts.

The above fix, listed by Tom saved us!! We did as instructed and took off the back of our 50 inch Magnavox plasma tv. We were not sure what we were looking for so we googled capacitator (image) & there was a photo of a fried capacitator! Sure enough we noticed ours were "fried", we took out the board and went to an electronic supply store, bought the 2 capacitators ($2.00 each!!) and then found someone who did tv repair to sauter the new capacitators onto the board. (It is important someone who know how to sauter and recognizes polarity do do this for you) All in all we fixed this following the above instructions for $34.00 and our time. For a month we were told to spend hundreds getting a new power board!
Kudos to you Tom & thanks so much!!

The problem is cause by the transformer on LIPS inverter (Power supply + Inverter board). You could see an obvious burn on the 1 of these transformers ( There are total 3 black transformer on this board). The part number is 4302H. It is available online at http://www.lcdparts.net/TransformerDetail3D.aspx?ProductID=2775
