Sorry Sarge...this problem is not that simple...and for some reason these Sylvania tv's won't allow you to access game mode that easy. I think the best idea (assuming the universal remote doesn't work out)...just buy another ORIGIANL remote from the manufacturer! Hooowah!

is there a TV/Video or menu button on the front of the tv? if so try the tv/video button, that should scroll through the the components you have on your tv. dvd, game cable etc. If no tv/video, hit the menu button and then use either channel up/down or volume up/down to scroll through your component options.

did you try to switch the tv modes Ex. my tv has av 1 av 2 comp 1 comp 2 does it have those modes

hit menu and then hit the up volume button once and thn you should have it by the way i cant play games on mine how r you playing games on yours?

I have the same problem with a 6420ff sylvania tv with a xbox 360. I plug the red white yellow into the front of the tv and it wont come on.

you have to get the original remote or buy the RR0108UD Anderic Replacement. im betting you have a Sylvania Tv. go here to get the remote: http://www.replacementremotes.com/store/productdetailp.cfm?productid=27278

go up to your TV and go into the menu. Go to the channel selection and run the auto select for channels. This will take some time but the TV will end off the first channel found, the only thing is you cannot get back into video mode without the remote

The remote control has a "Game" button, which is how you select the external input. Since you don't have a remote you can select game mode via the front panel Menu button:

1) Press the MENU button so that the menu display appears on the TV screen.
2) Press the VOL(ume) ▲ button so that "PICTURE" is selected.
3) Select the feature you wish to adjust with the CH(annel) ▲ or ▼ button and adjust it with the VOL(ume) ▲ or ▼ button.

GAME MODE: Set to the most suitable position for TV
GAME. [+] : ON [ - ] : OFF

This will place your TV into Game mode and use the front panel video/audio jacks.
