Home TV Repair, Part I
Got a flat screen HDTV in your home? These days, almost everyone seems to. There's just one problem: Unlike the CRT TV's of old, HDTV's simply don't last very long -- maybe 5 years at best before something goes wrong.
This has happened to me now. My nearly 4 year old Samsung started to cycle on and off when attempting to turn it on. If we left it alone, eventually, after maybe 5 minutes, it would finally turn on and stay on. Then 5 minutes became 10, became 15.... One day I came home from work about 6PM, and I noticed the TV cycling on and off. I asked my wife, "What time did you turn on the TV?"
"About noon," was the reply.
"You left the TV to cycle for 6 hours? I think it's safe to say it's not going to turn on."
"Well, it won't turn off."
"I can't reach the plug."
Sighing, I went into the den and unplugged the thing. At this point, I figured the TV was a loss. It was well past warranty, and I did not purchase an extended warranty because extended warranties are usually a waste of money. I could well imagine a service call would cost nearly as much as simply buying a new TV.
Then I starting doing a little research Googling the symptoms, and discovered:
- This is a common problem with Samsung TVs.
- The cause is one or more capacitors on the power supply board going bad.
- This is not just a Samsung thing. In general with modern electronics, if something goes wrong, it is usually a bad capacitor.
- Capacitors are dirt cheap and readily available at electronics supply stores.
