Colecovision Repair Part I

Fixing a Colecovision with a black screen. I didn't cut out anything so at times it may seem like I am wishy washy and not sure about what's wrong. I try to keep an open mind about the issues and in the end I figure out the issues. In part I, I find the first major issue that was preventing the Coleco from displaying anything but an angry black screen. 0:56 - Testing the Joystick 1:35 - Disassembling Colecovision 14:30 - Getting inside motherboard 17:13 - Initial Testing with Multimeter 23:57 - Looking at the CPU pinout and Reset pin 29:01 - Using Digital Infrared Thermometer Gun 29:27 - Using Logic Probe 30:48 - Testing CPU Reset pin with Probe 32:10 - Testing Video Ram Chips 35:17 - Spotting first issue 38:00 - Replacing faulty component 45:00 - Putting in new component 46:56 - Test after replacing it
