it looks like lighting strike damage. lighting strike often damage final power transistor , or TX / RX switching PIN diode. surprisingly many time RX front end was fine. I guess lighting energy have to go through Low Pass Filter , TX, RX switch before get to RX front end. please keep up with radio repair video, it is very interesting, and many other will benefit from your video. 73 AG6JU
Thanks! The next video in line will be on an Icom IC-207H that I believe also had lightning damage. It damaged the filter caps, pin diodes, and the HI/Med/Low controllers for the RF.
I wonder how dirty the underpants are of the owner of this radio. You could at least clean your radio before handing it over to a repair man. Just as disrespectful as the way the power cord is cut.
REALLY GOOD JOB on this repair 👍
Looking forward on you repeater setup. I have some old public safety gear I need to do something with !
I really like the Yeasu FTM Series radios.

Exactly.. i would expect that finals would be damaged and not that smd parts.... so i think that it was lighning strike as well
