It sounds like you are having an issue with the resolution of your MacBook Pro's internal display when it is connected to your TV which corrects itself if you disconnect and reconnect the external display. Is that correct?
This article has a lot of useful steps for troubleshooting display issues - Apple computers: Troubleshooting issues with video on internal or external displays. In particular I suggest the sections titled Check connections, Reset the system, and Reset the resolution.
Thanks for using Apple Support Communities.
Sincerely.
