Hey I’m not sure how to get into the service menu on my zenith sms7247s and I don’t have the remote any way to get into the service menu?

Runnerman Gaming that is a CRT monitor correct? Are you looking for the Setup Menu or the Service Menu? The common way for Zentih TV (if yours even has one) service menu would be something like this:

Turn ON the TV and hold down the “Menu” button on the remote control, till “Welcome Message” appears on screen. Now release the “Menu” button and within two seconds press the following buttons in sequence. [9] [8] [7] [6] - [Enter]. The service menu will be displayed. You can press [9] [8] [7] [6] - [Display] too to get into the service menu. Use these buttons to toggle between menu items and adjust data values stored Menu ▲/▼ ◄/► To exit from service menu, press the Power button on the remote control. An other way to enter the service menu is Press and hold the Menu button on the remote. The on screen menu will disappear. Now press and hold the Menu button on the front panel control of the TV. Keep both button pressed, until the service menu is displayed. To exit from service mode, and save the settings, press Power button on the remote control. OR Press and hold the “Menu” button on the remote control till enter password screen is displayed. Now try the following codes. 0-0-0-0 8-7-4-1 7-7-7-7 OR Press and hold the “Menu” button on the remote control and “Menu” button on the front panel of the TV, until Service Menu is displayed. In all cases, to exit from service menu, press Power button on the remote (from here) . You will need a remote for this. Retro gaming I presume?
