American DJ V2000 amplifier repair

Here is a video of me documenting my repair of an American DJ V2000 power amplifier. Because a schematic was unavailable, I had to rely on my electronics knowledge and experience in order to perform the repair.
This is not intended for unqualified or inexperienced persons to use as reference for troubleshooting - please be careful when attempting to repair high power amplifiers. I fix and design power supplies by profession, therefore, I possess sufficient knowledge and experience to know what I'm doing.
In other words, I'm not responsible if you electrocute yourself, burn your house down, or damage thousands of dollars of test gear.
