1990 Zenith System 3

[karmaman]

Hey guys, a friend gave me a Zenith System 3 27" TV, with a manufacture date of January 1990. When I plug it in, a green LED labeled "Stereo" starts blinking nonstop. When I push the power button, nothing happens. If I hold down the power button, I hear a click inside the TV, the green LED stops blinking for a split second, then the LED starts blinking again and nothing happens.

Any ideas? I'm OK at soldering, good at following instructions, and have a multimeter. This TV is old to me (I'm only 15) but it's kinda cool-looking, but I'd love to fix it. It's sorta cool having a TV older than you.
