    Not this time; this time it was widespread use of underrated capacitors:

    Thanks for all the links, ideas and letting me vent without clobbering my dignity. I have the POS torn apart and I'm waiting on two capacitors to be flown in from Minnesota. I'll keep ya posted on how the repair goes one way or another. If it works I might even take pics.

    You could post some of it now - is it bulge capacitor(s) ?
    Did you measure it ?

    Manufacturers were using 10V capacitors on a 12/13V circuit (which normally calls for 16V capacitors), which results in the capacitor running hot and failing early. This is going to cause a lot of people to throw away good TVs that need $5 (or less) in repair parts and a 20 minute fix.

    But TV companies generally don't replace individual components; they replace the entire board, which is part of the reason repairs are expensive. But this fix is simple enough that most folks who have used a soldering iron before could probably do it themselves. I've fixed a couple in 10 minutes (2 or so minutes working on the board), but I've been soldering stuff for 25 years (not professionally).

    A bulb in an LCD TV - 2 to 8 years, depending on the use and your luck. The LCD panel itself shouldn't fail in normal use.

    I know Panasonic plasma panels are rated to 100,000 hours, or 12 hours a day for 22 years. At that point, the panel should have lost no more than 50% of its brightness.

    CRT tubes? Most of them have a 10 to 15 year life.

    But the question is really moot. A plasma or CRT TV could well have a problem earlier with something small and inexpensive, like a bad capacitor.

    +1

    In general, our electronics is so reliable that we are suprised and disappointed when something breaks early. But there is one thing that I can absolutely guarantee you will happen with your electronics: it will break. I just can't tell you when.

    You bet! The way TVs are advancing right now, a three year old model is practically an antique.

    Too bad this wasn't a better capacitor failure. For years I watched TV on a Sony two piece projection unit from the early 1980's, with a large coffee table that housed the guns. One day there was a loud pop and flash, followed by a huge cloud of smoke. A few seconds later there was no red gun. After 19 years, it went out in a spectacular blaze of glory.

    I replaced 4 caps in my 40" Sammy LCD about 6 months ago, and it's still going strong. Local repair shop quoted over $800 to repair it (they claimed the entire display panel needed to be replaced). Since I could buy a new one for less than that, I figured I'd take a shot at doing it myself. Fixed it for under $7 with caps from Radio Shack.

    I hope your experience turns out as well.

    After replacing the 2 suspect capacitors (the tops were domed) with no change in results, I continued my online quest for answers. I'm now looking for a y board and a z board. Replacement costs vary new vs used and there is no guarantee that that is the problem. I've replaced the offending Vizio. When my urge to go postal on it dissipates I'll take up tinkering with it again. Thanks to all for the help and support!

    What did you replace it with? I ask b/c I have a Vizio with a March 2007 mfg. date, so I might be in the market soon...

    It sure looks as though it still applies.

    If you bought it from Costco it would be under their original return policy. I returned one I bought about the same time when the HDMI inputs suddenly stopped working. They gave me back $1370. I turned around and bought a 50" plasma (720P-->1080P).

    Vizio isn't the only one that has problems. I bought a $3K samsung plasma at the end of 2007 and 9 months later the techs where here replacing the panel and power supply. I called Samsung 3 months into ownership and questioned the excess amount of heat and said it was normal. Guess I was right. Now to this year, same issues come up again. I call and they authorize the repair out of warranty which was GREAT! Tech comes and replaces panel and power supply again. 30 mins after he leaves the whole screen develops a green hue and then it was attacked by the "black plague". The bottom of the screen started turning black and then progressing upwards until 90% of the screen was black. Oh yeah, with the first repair the techs had to replace the replacement panel because the replacement one sent the first time was bad. Thankfully Samsung was great with agreeing that there was way to many repairs on this set and agreed to replace it. Now I have a new 2010 plasma that is only 1 1/4 inch think and is tons cooler (heat that is) plus has some cool new features! So even higher end TV's can and do fail all the time.
