Picture goes off sound stays on

no picture is due to the vertical and horizontal ICs problem.

First when tapping changes the picture you have somewhere a bad connection; in electrical board or wiring.
When the screen goes blank after a while means some capacitor is bad/old.

Ouch! Ok... don't turn it on!!! If it's plugged in, unplug it. Get papertowels and clean off as much of the outside spill as you can. I would recommend taking the TV into a pro and letting them clean it out completely. A good TV repair shop can clean it up properly by taking the components out and reassmbling the unit. If you are electronic saavy or have a friend who is, you could possibly handle the clean up job yourself, but if the TV is still under warranty, you will want to have it professionally cleaned.

Hi:
If lighting struck the television then there may be a problem with the power supply, first thing to check for is the line fuse, if no standby light is lit on the front when you plug the set into AC outlet then the line fuse is blown and needs replacing.

It seems that your unit has some sort of Video side, PSU fault, or a problem to the Video section that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

Look for Bad capacitors on power supply board they will be vented or swollen on top 220uf 10v 330uf 1000uf 16v

My Westinghouse SK-32H240S television fails showing picture. Only sound can we hear but no picture.

Lines, and the screen going black are common among this particular T.V., but some solutions to a similar problem were posted here.
