Question about Sony KV-27V22 TV
Hello, I turned the TV off at night and tried to go to sleep. Everything was working perfectly with the TV and it had been working perfectly that way since I bought it(9 years ago!). After I turned it off for no more than 5 minutes, I heard a loud sound like something bursted (sounded like "pak!") and there was burning smell coming out too. I believe there was a flashing light coming out too -- but not sure because my eyes were closed and the loud sound may have caused the brain to imagine the flashing light. It was late at night and I figured it must be a blown capacitor or resistor. In the morning, just by curiosity, I tried to turn it on with the remote controller and it didn't turn on. No sound, picture, red indicator light, or relay clicking or anything. I tried to push the ON switch on the unit directly and there was nothing -- complete quiet. Obviously there was no power feeding anthing. I opened the back cover, removed the circuit boards, and tried to find a blown component. I tried for a few hous but to my surprise, all circuit elements appear to be 100% inact! The only fuse in there is also not blown. There was no indication of what may have bursted at all. Everything looked clean or evenly covered with a thin layer of dust. The picture tube and the copper coil looked ok -- no burn, broken, or anything. Do you think it's the flyback transformer? Or anything else I should be looking at? I'm still wondering where the burning smell came from. Thank you!
Dude, i believe that your flux capacitor is blown

Yes what you discribe kind of sounds like a Flyback Transformer, like a light bulb at you house they've been known to go out when you least expected it. I am not sure what make or model your TV is, but many TV's use the Flyback Transformer to power other parts of the TV, so when they go everything goes. You might look for any cracks on the Flyback, this is a sure indication it is gone. Electrolytic Capacitors can fail causing a loud hum in the speaker.

You Probably have a bad flyback transformer(The HI VOLTAGE) and a defective horizontal output transistor. I you have training in the tv repair , then you can go to http://www.partstore.com and getthese parts. they arte soldered in so your gonna have to know how to solder and unsolder as well. You should also know all the safety issues regarding the HI voltage in these sets. If you dont I highly advise that you take this set to a pro for repair as theres hi voltage inside these sets even when they are unplugged. Good Luck
