Atari Lynx No Power Repair

Today I show a problem I've not seen on an Atari Lynx before and I can't find any information about this either but it's definitely something to check before throwing in the towel.
For reference, if you DO have a faulty MOSFET in your Lynx, the original part is Q12 on the PCB (Q13 on the Lynx 1 I think) and the part number is MTD3055E. The modern replacement for this would be STD12N06. Of course as this video shows, it's not always this part at fault so try everything you can before you go hunting one of these down!
