Solution to these problems:

2.

-It was discovered that the transformer T1007 was damaged. The case was broken off from the board and was held on only by two soldered wires out of five. Possibly damaged due to shaking while driving off-road.

I restored this part by hand, rewound it with a new wire and soldered it, then secured it with glue.

After this repair my transceiver FT-857D started working like new again!!!
