The thing about these consumer tv's is that they use the most grossly cheap electronic components in them so that they wear out quickly. the main power board is faulty, could e several small capacitors or a transformer , but a electronics service tech will need to do the work unless you have used a soldering iron and are comfortable with it. A replacement power board may be found on ebay for your model tv.
and last purchase a backup power supply to condition the electricity so that the tv will get smooth electricity from now on. hope this helps you . good day

I think you chose a Westinghouse Lemon, go this site and read all of the negative reviews of this model;

http://reviews.cnet.com/flat-panel-tvs/westinghouse-sk-32h240s/4852-6482_7-32429419-2.html?tag=userReviews;page

Here's just one of the reviews;"best chunk of aluminum i ever had the fortune to buy"by stevecox25 on June 11, 2009-->
"Horrible customer service on a worse television" by westinghousecrap on March 20, 2009 Pros: Good picture once it is properly adjusted.
Cons: Low quality audio, had the TV for 10.5 months and the picture went out, sent the TV at MY expense to TX, and I've been waiting for 2 months, and customer service can only say that there is a "delay". And they don't send a new TV, it's a rebuild.
Summary: Please don't waste your money on this TV, spend a little more on a different brand and save yourself the headaches I've had. I'll never purchase a Westinghouse product again. Customer service has been no help, and their answers are vague at best. Learn from my nightmare, NCAA march madness on a old 19" TV because my Westinghouse quit working 2 months ago and they still haven't replaced it.

No picture, good sound


It's most likely the video board. The menu is injected at the output of the video stream right before the LCD panel. Having audio indicates the signals are getting from the inputs through the input switcher and audio boards. Unless you have electronics experience, I suggest having an experienced tech look at it.

Audio but no video


If the screen is not illuminated this can be from the screen power supply, the main screen driver board, or the screen itself has failed. The service rep will change boards to service this, and adjust as necessary.

The set will require factory level service.
