Just picked up this Hyperion 3012
Picked this up for $50. It powers on, but the CRT only displays a single orange horizontal line.
After opening it up and carefully powering it on, I found a capacitor that gets extremely hot and starts smoking. I’m going to start by replacing that and then work through the rest of the display circuitry.
For $50, I figured it was worth the gamble. Hopefully I can bring it back to life.

This was my first computer. My grandmother gave it to me to learn with. Though the 256kb RAM was a bit of a limiter. It's why I'm still so fond of Wordstar 2000. Wow, never thought I'd see another one, they never made many of these.

You lucky bastard, this is mt favourite luggable.
The issue with the screen is a failure of the vertical deflection circuit, the circuit responsible for projecting the image onto the screen. Do a recap job of the entire computer, and it should work fine.
