I'm most likely going to need a new 50" TV, since the fluttering electric supply fried mine yesterday. The other TV is a Vizio, so I want another similar one so the remotes will work on both. I don't want to go to a store and deal with teenage salesmen trying to up-sell me and then try to fit into my Honda Fit, so I'll be shopping online.

Amazon has a Vizio like mine, renewed, for $339. A new version of that one is $500. I've had good luck with refurbished cameras and hard drives, but I'm wondering about a renewed TV. Nope! The renewed has a 90-day return policy, while the new one has a 1-year warranty. In addition, the new one comes with a polishing cloth!

Vizio vs Samsung - 50"

Time to start looking for reviews!

Were you using rechargeable batteries?

If so, those have a limited life span. Often when they're a couple years old... or maybe after some number of discharge/recharge cycles... they may show a full charge, but under load in the device will actually fail quickly.

I've had some batteries "recover" after a series of charge/discharge/recharge cycles. At first they would only work briefly in camera or flash. But simply repeating the process a few times seemed to bring them back to life and they were usable again.

If not too expensive, new batteries are probably a better option than ones that have failed previously!

BTW: I found that rechargeable AA gave more shots and recycled faster than alkaline AA in my 580EX II and 550EX flashes. The cost of single use alkaline was also a problem. I have six flashes and three compact battery packs that hold additional batteries. It takes 48 batteries to fill them all, so I had more than 100 rechargeables when I was doing a lot of flash work.

It's also possible for a charger to go bad.... though I think that's less common.

You v**ed for chump, you support his ideology.
You sit silently by while he trashes the constitution that ALL Republicans hide behind, you are part of the problem.
You support Moscow mitch, you are part of the problem.

You stand idly by, while chump sends - NOT troops but, mercenaries into Portland to beat up on innocent and helpless protestors, you are part of the problem.

Get a backbone - STAND UP FOR WHAT THIS COUNTRY IS ALL ABOUT! It's NOT about the rich and the powerful.. it's about opportunity to live and let live.
