Troubleshooting dead board with multiple shorts

Hello, I’m an installer who’s done upwards of 40 DCHDMI/DCDigital installs, and I’ve encountered something strange with a unit that I installed. Everything tested fine and passed my 6 hour stress test, only to arrive with the customer and not be functioning. Specifically, the console turns on briefly and shuts off, what I suspected to be a short somewhere in the console.

After disassembly and various troubleshooting methods to track down the short, I found it to be on the DCDigital board itself (upon removal, the console powered up).

Now, I believed I tracked down the short on the board to the ESP module as I was getting multiple shorts on its pins. Replaced with a new module and the original indeed has shorts to ground. However there are still multiple shorts on various components on the board so I’m at a bit of a loss trying to track them down. I’m hoping Chriz or Dan might have some insight into solving this mystery and getting this customer’s board back up and running.

Thanks in advance for any insight anyone may have!

Multiple pins will have some type of shorts. Normally when a DC turns on then off its related to the fan. Can you confirm the fan spins at bootup and is plugged in tight?

Yeah I confirmed the fan is connected correctly, I’m testing for shorts against my known working test board and seeing inconsistencies when comparing with that board.
