Sounds like the final transistors are toast to me. Maybe the driver transistor, too. Do you have the tools to replace transistors? If not, you're going to need to send it to someone.

Check the 2SB827 and the 2SA1869 right next to it. You'll find the 2SB827 mounted on the chassis on the same side as the audio chip. Those can fail also, causing no TX.
