Looking for Answers about samsung 3D Active Glasses?

Although it can't be said for certain, it's unlikely that they will. Currently there is no set standard for the method of communication between the glasses and TV, so the chances of two companies using the same technology is unlikely.
Never say never though!

Currently, there are two different types of glasses available from Samsung which are not interchangable between the 2010 and 2011 series TVs. Although the glasses are supported between different display types (LCD, Plasma etc) they will not work with different generation TVs.

As for future models, it's currently uncertain. It would seem that Samsung have really nailed it with the 2nd Generation glasses technology though, so i wouldn't see why they would change the design unless they see a product, or financial, benefit in doing so.

it takes about 2 hours to fully charge the battery via USB but should be good for 30 hours of viewing content.

The glasses come with a USB cable.
You charge them from your computer or any USB source.
There are two USB ports on the back of the television.

No- there's no need for firmware upgrades in what is considered to be pretty standard IR (or bluetooth depending on the glasses) technology; in the same way your TV's remote control doesn't need firmware upgrades.
Any issues which would possibly warrant a firmware upgrade would more likely be something that is a hardware defect than an issue which is resolvable by soft-updates.

Not that we're openly aware of- the root cause could be many things from a faulty LCD lens, to simply some broken wiring.
If you bought them recently, you could try dropping down to the retailer to exchange the faulty pair.
Else, your best bet is to register a Samsung support account from the main page, and file a support ticket for assistance.

Which model number?

If the glasses still function, then your best bet is to "DIY" fix it. Superglue or whatever. For the cost of repair, you could probably easily buy a new pair.
For a more definitive answer, you'll need to register for a support account from the Samsung main page and file a support ticket; else give Samsung a call, or contact an authorized reseller/repair centre for assistance.

Could you provide us with a model number of the product you require assistance with?

YOU WONT BE ABLE TO SEE THEM SHUTTER THEY SHUTTER 10 TIMES AS FAST AS YOUR EYES CAN , ITS YOUR CHARGER, TRY USING A DIFFERENT CHARGER OR BENDING THE ONE YOU HAVE AND THEY SHOULD CHARGE FINE

THERE ARE SOME GLASSES THAT ARENT ACTIVE GLASSES , BUT DEPENDING ON THE MAKE OF YOUR TELEVISION , ITS HARD TO TELL YOU WHERE TO LOOK

The red light remains lit until fully charged.
Then, while in use, the light shuts off,
even though they are still on, to conserve power.

That manual can be downloaded from the support section here on samsung.com. I recommend taking the time to REGISTER all your Samsung Products via samsung.com. When you are registered via the site you can access drivers and other updates for your particular products from THE MY ACCOUNT link while on SAMSUNG.COM.

Sounds like a fault. You could try and obtain a replacement pair from your retailer, or register on the main Samsung website for a support account, register the glasses by serial number, and request support that way directly to Samsung. Samsung should then be able to arrange for an RMA for you if the product is faulty.

The glasses need to be charged from an ACTIVE USB port. I was turning my TV set OFF, therefore the USB ports were NOT active and my glasses were not charging. Leave the TV ON or use USB ports from another source, a computer, for instance. men

WELL , I HAVE 2 PAIR AND WHEN THEY ARE DEAD ITS A RED COLOR AND WHEN FULLY CHARGED THEY ARE GREEN , I WOULDNT BE TO WORRIED IF YOU GOT THEM AT A REPUTABLE DEALER

no it turns off to conserve power

a standard MICRO-USB cable will charge the glasses, but make sure it is a micro-usb cable and not the regular usb cables that you normally get.

In the menu is an option for 3D depth, you could potentially try adjusting this setting to avoid "ghosting" or "crosstalk". On the basis that you don't have this issue normally, i could simply be a problem with whatever input format you're using (ie. Digital Content vs Original Bluray media)

I assume you're referring to the DreamWorks Animation 3D Blu-ray Disc titles currently available exclusively on a "bundled" basis with Samsung products. Although you can of course call Samsung and make your case as an already-existing owner for being entitled to a copy of (one of) the DWA 3D BDs, the idea behind the promotional bundle is to incentivize *new* sales. The movies were--and to a certain extent still are--available on a redemption basis in the "starter kits" available online and at retail which contain two pairs of Samsung glasses and a voucher to be submitted via mail or online to receive the BD via mail. Unfortunately, the MONSTERS VS. ALIENS promotion has concluded. There is still time as of this writing, however, to purchase a kit, sell the glasses if you don't need them, and submit your voucher for HOW TO TRAIN YOUR DRAGON, the SHREK films and, in a promotion that just started, MEGAMIND. Of course, many of these discs are also available through the standard third-party, used outlets as well.
