Is it possible to fix a working flip phone with no visual display?
The missing visual display is either a problem with the phone's monitor or a connection problem. you will need to call the phone company and ask them about repair options for the phone.
I do not think it is possible due to absence of Visual Studio for mobile platforms. You might be able to install SQL Server Management tools but not same one you are using on your PC. If such tools exist, they would be provided by 3rd parties only. You might want to check online store for you phone.
