My nice little 19" Westinghouse TV lasted just over a year before it died. It had been working beautifully until one day, it refused to turn on. The little power LED wouldn't even flicker. I called Westinghouse and they said that I was out of luck because it was no longer under warranty. Shoot.
After some Googling, I discovered that my particular model (SK-19H210S) is notorious for this exact problem. Every review I read told the same story: "It lasted a year and then died! Westinghouse told me I was S.O.L.!"
Time to break out the ol' screwdriver and take a peek under the hood.
My first suspect was the power supply board. Possibly just a blown fuse? After taking the TV apart, and inspecting the power supply, I found the culprit: a bad 2200uF capacitor. One lousy capacitor goes and the whole darn TV is useless! Sheesh...
I have a sneaking suspicion that Westinghouse bought a got bad batch of capacitors that only lasted for a year. If I am correct, than replacing this one little part could revive your poor little TV!
These instructions are intended for only this specific model of TV. Even if you do have the same model, it is still possible that the problem is something completely different. It might be worth a shot though. The worst you could do is break it. If its already broken then whats the difference?
A word of caution: You may encounter high voltages! Capacitors can store a lot of electricity. It is a good idea to discharge capacitors by shorting out their leads with a plastic handled screwdriver. Wear safety glasses while doing this!
Skills:
Basic soldering
Tools:
Safety glasses
Multimeter (for checking faulty components)
Phillips screwdriver
Plastic pry bars (For getting the case apart without scratching it. An old credit card might work too. Try a butter knife if you don't care about scratches)
Pliers
Tweezers
Soldering Iron
Towel (to keep the screen from getting scratched)
Hammer (for if it doesn't work and you get frustrated)
Materials:
Solder
One 2200uF 16v Electrolytic capacitor
Aluminum foil tape (duct tape or Gorilla tape might work in a pinch)
Cost:
FREE (if you scrounge, $3 at the most if you don't)
If you have all the tools, then all you need is the replacement capacitor. I scrounged one from my pile of electronic junk.
If you don't have one on hand, try a local hobby shop or RadioShack. I did a quick search on eBay and found a lot of 5 for $2.50 including shipping.
Just make sure that the one you're using is a 2200uF electrolytic capacitor with a 16v working voltage.

Signing UpStep 1: Case Disassembly
Getting the case open can be tricky. Just pay attention to how it all comes apart because you will have to put it back together when you're done! Pay attention to which screws came from which holes.
If you are an experienced TV-disassembler, skip to step 7.
Tips:
It helps to keep small parts in a dish or a cup.
Taping screws to a piece of paper and writing notes helps you remember where they go.
Marking or labeling parts and wires as you take them apart is helpful when it comes time to reassemble.
First, remove the front speaker cover by prying it downward. It is just snapped on, no screws.

i replaced the bulgingcapacitorr , now i turnTV on an the screen lights up an then off ?have sound but no picture after start up .
Now, I need to find in which box I stored my soldering iron in as I recently moved as well as a place to get the replacement capacitor. Can't thank you enough. If it was not your article, I wouldn't figure out how to disassemble this monstrosity and most probably chucked the whole thing into trash. Yay...
By the way the 2200 mfd cap is bad on my tv too. Your help will be very much appreciated. If I can't reconnect the flat ribbon, then all my efforts are in vain.
Thanks
Push the cable back into the slot until it feels like its gone all the way down. Just don't force it and make sure its facing the right way.
Good luck!
Thank U
Happy to help! I hope it works
