Hello everyone. I am new to the forums.
I have an old Atari 5200 from my childhood.
I recently tried to hook it up to my LCD flatscreen TV.
I followed the instructions at http://www.atariage.com/howto/connect.html and purchased a "Coaxial (F-type) to Female RCA Adapter" and hooked this into a Coaxial switch box. This switch box connects my cable and Atari 5200 to the Coaxial input in the TV.
When the switch is activated, I am getting a blank screen and my TV reads "no signal". However, I am getting audio.
Even more odd, I have the 5200 to 2600 adaptor at http://www.gamepodunk.com/gallery/image/1882-atari-vcs-cartridge-adaptor-for-2600-games-on-5200/. When I place a 2600 game into the adaptor and into the 5200, the video and audio work.
I've seen a few other similar topics but not these exact symptoms.
Thanks for reading and any advice you may have.
Cheers!
