My TS450 had a similar symptom and Kenwood replaced an IF transistor to fix
it. This was about 10 years ago so I cannot recall which transistor was
changed.

Anyone encountered this: When placed into transmit mode by any means,
radio will not drop back into receive mode. Doesn't emit power unless key
is closed etc, but VOX does not disengage. The only way to get it back to
receive is to punch a front-panel button like PROC, RIT, etc. Other
problems that may or may not be related a no display on power meter but
unit produces 100 W; RIT doesn't function although light comes on. F.LOCK
is not on, the main tuning control changes the displayed frequency. If I
tune from 1501 kHz to 1500 kHz the receiver seems to fail. Retuning to a
frequency above 1500 kHz does not return reception; I have to punch one of
the above-mentioned buttons to get it back. There are no optional filters
or other accessories installed. When I can get it into receive mode there
is plenty of noise to indicate the receiver is working, but doing anything
to activate the VOX kills the receive. VOX DELAY, ANTIVOX and VOX GAIN at
full CCW, problem occurs with or without headphones plugged in, and
whether I key it with the XMT/RCV button or via a key, or the PTT button
on a mic.

This was an eBay purchase, supposedly working 100%. Nothing rattling, it
was double-boxed and the outer box doesn't show signs of rough handling.
It's probably going back to the seller but if anyone has a simple
suggestion I'd appreciate it. After the problem is resolved somehow I will
discuss the name of the dealer from whom I bought the radio.
