I'm having a very hard time finding the wall mount for my Sharp 37" LCD TV. No info on Sharp's site. Some online stores package the TV with an Omnimount, but I can't tell what model it is. Can't find a definite answer from Omnimount itself either. Also, so far I can't find any store (I live in NYC) who will install it on the wall for me (because I didn't buy the TV from them). Any advice will be appreciated. Thanks.
