If you use a dummy load and accurate wattmeter the internal meter is pretty close to the real power into a resistive load.
Any reflected power over a 2:1 swr will cut the output to half power. This should keep the finals from frying unless those bandpass filter relays are not working right.
The problems I had with my new/used TS440sat having low output seemed to be from intermittant push pins on the ends of cables connecting to the boards. I was lucky to get things working again.
I also have the common VCO problem where on the bands above 20 M I have an awful chirp on CW and unusable SSB mode. Using FM on ten meters works. CW on the lower bands is fine, so I will just let it go. It's a major pain to take all that stuff apart just for SSB and bands that are not open too often .
...I work on radio problems all day at the job so don't like to do much repair during my off hours for fun ! Maybe I willl after I retire.
