Tektronics 464 - Sweep generator problem

My Tektronix 464 does not generate any sweep. X-Y is ok, voltages are ok.

Is it normal, that U980 (sweep control IC) is getting "hot"? I can hardly touch it for more than a few seconds.

I can see the trigger signal at pin1 of U980 but no other signal except DC-levels on any other pin.

Thanks for any hint, Falk
