I have Microsoft Xbox 360 Universal Media Remote and can't get the TV codes to work on my Viewsonic TV. I tried manaully scaning for a code without luck. Can any one suggest a TV code for a Viewsonic N3760?

Just to be sure go thru the steps for the remote to scan properly:

If you already went thru these steps then I would suggest going to this page:

http://www.xbox.com/NR/exeres/3D295224-0688-4AFE-B6AB-0580AD69C86D.htm

It has all the codes for viewsonic tv's. If you go thru all these codes and you manually have the remote try to find a working code but to no avail, then the remote is not compatible with your TV, but there is always the last step of calling Microsoft support:

If they cant help then you know for sure the remote isn't compatible with your TV.
