Some things that would help in recomending a remote:

1. Post question in correct forum here -> [Link: remotecentral.com] or [Link: remotecentral.com] . A $4.00 remote ([Link: cgi.ebay.com]) is generally not considered a pro remote, so the people lurking in this thread probably won't help you out.

2. Give more details, like what model TV. Just saying it's a Sharp doesn't cut it, there are alot of Sharp models out there. There should be no reason that your model remote shouldn't control your TV. What code are you using?
