It still won't switch on. I Googled around and it seems this has happened to a few people but I haven't been able to find many answers short of "send it back to Yaesu for repairs". Any advice is appreciated. Schematic attached. It attaches to a heatsink which mounts in the case with a cooling fan. Assembled weight is about 7 pounds. This one had parts that had literally exploded while the supply was running on standby. They have a reputation for being unrepairable - they are very complex - very dangerous V on MFD of electrolytics - can evaporate a scope probe - BUT I have repaired close to 50 of them.

This radio is in good shape. The right side features a carry handle making the radio easily moved in a pick up and go environment. Included with the radio is the original box , manual , new MH hand mic and power cord. It mounts in place of the battery the bottom-inside of the radio. There was actually 4 of them in a square pattern. After removing the one closes to the ground symbol, it appears to be one of the 4 short screws that hold the transformer inside the box.
I went ahead and placed my grounding wire outside the box fasten to the screw with the washer and tighten it. I've used the power supply for a couple of hours and it has not moved from The instruction stressed the placement of a grounding wire and I remembered the old Drake power supply for my TR-5 had one built in and a 3 prong plug.
