Hello,

1. We are not samsung
2. Did you receive some type of coupon for the free glasses?
3. Did you ever consider that samsung sales millions of products and maybe a lot of people bought this tv with the same jibe you where going to get FREE glasses?

Listen, We are Fixya.com a do it yourself fix site for many products we are not the manufacture.

you might want to lodge a complaint with www.comsumerist.com, www.bbb.org www.ftc.gov about these sales practices.

1. if you have to received a coupon or some redemption code from the retailer then the likely hood that your going to get FREE glasses is a LIE.

You got a couple options:

1. Deal with it
2. take the tv back
3. or complaint until you have to check yourself into a hospital.

The fact is here you should have never took there word for it, FREE does not come with bows and ribbons nor in paper or plastic, you got to fight for FREE stuff do not believe me check out youtube and see what people would do for something FREE.

1. Stay calm (you think if i was samsung that i am going to give you free stuff yelling?)
2. Be polite (do not use all caps in your emails, or correspondence it gets you no where.
3. Relax talk to the people Nice even tho its a inconvenience using threatening behavior will get you no where but the door trust me I got kicked out of places for not being civil learned from my mistakes.

4. people have hearts,lungs,feet,ears, mouths, just like you do BE NICE, KIND, respectful, professional.

Put yourself in there shoes would you want to hear a angry client?

Thanks for using Fixya.com and not samsung.com you got the wrong people!! Please be considerate, NICE, take my advice


LIVE LIFE!!

God Bless!!

Caps can fail with no outward signs. It takes a special meter to test them. Your set may have a back light inverter that powers the back lights. When it fails, the picture cant be seen, but you have sound, to check this look for a picture on the screen using a flashlight

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should be troubles hooted. Contact any service technician. The circuit will differ with models and versions.

Hi, not sure if you have the same fault as i had, but our tv only had half the screen go off, after looking up on the internet i found a video for a fix, what you need to do is remove the back cover, there will be ribbons that go from the front screen to the main panel, i removed each one at a time and rubbed the contacts of the ribbon with a rubber on the end of a pencil, plugged them all back in and switched it on and it was now spot on, thats more than a year ago and its still working spot on, hope this helps
