After recapping my Macintosh classic I was still getting the checkerboard pattern and while I was probing for voltages the screen went out and there was no High voltage on the CRT. I did check the fuse, replace the mofset, and after checking the voltages the connector from the logic board to power supply everything was connecting and a perfect 5V and 12V with logic board plugged in. I know there is no high voltage generated when the power supply detects no logic board so does anyone know what could be holding it back from powering on? I haven't checked my cap job too well so I will check that tomorrow morning to see if anything is shorting. Thanks, anything helps!
