This is a very interesting video to get a good view of the CLD-D502 inner parts, how to navigate the various parts, and how a single capacitor on the power supply was causing the whole player to go dead. Nearly no cut in the video, making it very practical to follow.
120V applied to primary, nothing was going to the secondary (various +5V, -12V, etc.) on the diodes.
Culprit was the PSU's capacitor (1uF/200V) on the primary stage of the inverter.
=> Player saved, well done!

If the two fuses were blown that means something after the fuses is pulling too much current. As for D105 that is not a diode, it is an arc suppressor, it should measure open. If it was bad your primary side input fuse would blow.
First power on the board isolated from the player. You should read +5volts on the EV+5V signal. Then short that to the power on pin and if the supply comes up with all voltages then the supply is good. If good then you need to focus on the other boards in the unit and measure for voltage line shorts. |

Well done!
At least, we know that the error code can be trusted.
=> H2 or A0 = Power supply abnormality error
