A:AnswerNot through Best Buy but if you contact Sanus, the manufacturer, they might be able to because they usually have replacement parts for their products. If they don’t, then unfortunately no.
A:AnswerI don’t know about your specific tv but it is a universal mount, so it should work. When we bought it we did not check to see if it would work with our tv We just bought it and it works/fits just fine
A:AnswerI doubt that you can get brackets seperately, but you may be able to take the original to a fabrication shop and they may be able to make more.
A:AnswerTilt can be adjusted if that is the problem. Also, make sure screws used to attach supports to the TV are not too long. If they are too long, they will feel like they are tight but the support will not be firmly against the TV.
A:AnswerDepends on how much you want to raise the TV. If it is a 1/4 to 1/2" you might try adjusting both level adjustments down. More than that you will need to detach the supports and reattach using different holes.
