Got a Galaxy 33hp2 stuck on one frequency. change bands and channels but still transmits on one frequency. Any ideas?

Umm, is this frequency around 25 MHz?
Or is it higher than that? When a radio loses control of its frequency, this can suggest where to look first.
Has anyone been twisting the radio's adjustment slugs with his/her eyes closed? Years ago we would see a lot of radios that had been "adjusted" off the air, but not so much these days.
For that matter, has anyone tried (without success) to fix it? We find that every unsuccessful attempt at fixing a radio will introduce at least one new fault it didn't have before.
That little fact can have a LOT of importance.

it’s stuck on 27.495
Not sure if anyone tried messing around with it or not I bought it used. A-d bands it won’t key, e and f it will key that frequency and swing plenty of power. Selector switch isn’t bad

The PLL is out of alignment somewhere. Or possibly the VCO frequency is off.
It sure sounds like it's had the golden screwdriver in it...........
Yes, sounds like PLL/VCO problems.
I had a few radios just like this.
to start:
at IC-5 pin-1 check for around 7.5 volts.
check the voltage at TP2 and measure if it changes
when going from CB ch 1 and jumping to ch 40.
check signal at TP3

Pin 1 on ic5 has 3.5v on band d, the rest of the bands have around 7.5. Voltage at tp2 channel 1 is 3.4v Channel 40 is 2.9v. Im guessing I have a faulty component causing the low voltage on band d
me drinking some hot strong coffee all early morning here.
but you probably have this:
check the signal freq at TP-3 the PLL OFFSET OSC section.
do you have a signal at IC-5 pin 2 ??
CB ch. 1 should be 2260 kHz
the binary code to IC-5 11100010 (226)
