I originally found this at a Flea Market, and had to replace the power jack on it. When I installed the new power jack, I accidentally cold worked the upper lead until it came off - the lead from the old jack was still intact, so I was able to replace that as well. When I went to test it though, the screen was black with some white flickering, before it went completely black, with no power light turned on. I've checked the Fuse, and the Fuse is able to to pass a continuity test. I'm confused at this point, since the fuse is the only thing I can think of that could be preventing it from turning on, especially with the power light off. Any suggestions? Could the polarity be getting mixed up somehow? I did have to remove the RF module temporarily in order to get the power jack on.

Edited 8-28-2016: The Power light does turn on when the switch is on - I took it to the local professional tech, and he thinks I may have accidentally fried something when I removed the RF module to put on the power jack. (apparently you can bend the RF module to some extent without desoldering it in order to fit on the new backplate/power jack.) He tried using a different RF module, Power Jack, and Voltage Regulator (if I'm remembering correctly) with no response. When I test it, I put in the cartridge, turn it on, and nothing appears on screen.
