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. :D 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. :scratch2: 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...

The sets that size have audio quality that is extremely poor. :sigh: |

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):

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

Damn i fell for this... I was about to open a truetone flatscreen that was given to me with a power up problem and start looking for batteries.....

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