Need to find manual and remote for 50 inch phillips TV

Go to ebay.com or amazon.com or go to a local reatiler store like walmart or go to tevelsion store. Maybe some place have your remote.

What's the model number? Knowing that will help you greatly to find the manual, and possibly a replacement remote.

Otherwise you can try different universal remotes that seem to have all the necessary buttons. Before purchasing from the store though, find out what their return policy is, just in case it does not have the codes necessary to run your TV. For this obvious reason, I would not recommend purchasing the remote from online unless it is a factory remote and not a universal.
