Failure of cheap Coby 15"
Toward the end of 2012 I reported the purchase and brief life testing of very inexpensive Coby hdtv:

Turns out that one of the original King Kong brand AAA cells had failed...0 volts (the other was fine). Such poor quality control... I guess that I didn't expect much anyway. jr |

Were you able to get the TV working again by replacing both batteries? I think those are backup batteries, so if they fail the TV won't work. The backup batteries keep the memory chips and others from losing their programming when the TV is off; if the batteries fail, the chips lose their programming (including stored channels, etc.) and can cause all sorts of other problems, including shutting down the set completely. (I will remember this if my own flat screen TV suddenly refuses to turn on or if I start losing my stored channel lists, etc.; same with my Roku streaming video player and my LG Blu-ray player, all of which I think also use at least one battery for system backup.) BTW, now I'm wondering just how many flat screens are discarded every year just because these backup cells have failed. After the TV has been working well for some years, the owner discovers the set won't power on, so in the trash (or to the recycler) it goes, when the problem may be simply dead backup batteries.

I doubt the majority of flat-panel sets will outlast the (in)famous 1990's Zenith CRT"s !!

I think he's joking about the remote batteries...

It wasn't the remote batteries that the OP was referring to! It must have a set of cells, that maintain the memory, channel presets etc.
The sets that size have audio quality that is extremely poor. |

I'm just saying, I worked on literally thousands of flat screens for over 5 years, and have never seen a battery inside a TV. TVs nowadays use NVRAM that doesn't need backup power to retain data.

Bingo! Coogar nailed it... a little tongue-in-cheek post about a *trivial* failure of the cheapest bottom of the line flat screen set that I have ever seen, after over three years of operation.
After all, it is a well reported "fact" here that these things can't possibly operate past the end of the waranty, or two years, which ever comes first. jr |

Drat those King Kong batteries! You need some of these batteries that I found in a remote (sorry for the crappy cell-phone pic):

My Insignia 19" FP has been working extremely well for five years. As I said in a previous post, the very first flat screens may have lasted just two years or less, but the technology has improved greatly since then. The only sets that will work for just two years (!), if that long, would be the under $100 no-name (Craig, et al.) sets available at CVS or Rite Aid. Those TVs, as another poster mentioned, are very cheaply made, with bargain-basement capacitors and such, and cannot be expected to last very long. I don't use my flat screen that much, anyway (perhaps three hours a day), unlike sets that are on all the time or are used a lot, so I am expecting mine to last somewhat beyond its current five years (the TV was manufactured in May 2011, according to the sticker on the back which also has the model number and software revision code). When it quits, I will replace it with my 20-year-old 19-inch Zenith Sentry 2 CRT set, so I am not concerned about the FP's eventual failure in the least.

I can't wait till super capacitors replace AA and AAA cells in remotes, wireless mice, etc!

I thought Truetone--the Western-Auto brand went out of business in the 1980'S?
Maybe this post is just another "red herring" ? |
