Scope 54610B no response from time interpolator

Hi, I have a scope 54610b, when I turn it ON, display is ok but there are no waveform trace displayed and an error message "no response from time interpolator". In ROLL mode, trace is normal and amplitude and time measured are ok. All front panel button respond correctly and GPIB interface is ok. I checked inside SCOPE, TRIG signal from input CH1 or CH2, I followed TRIG signal through some gates and signal are OK. But I didn't find time interpolator IC....I don't have any schematics. Somebody have an idea or schematics to help me to resolve this problem. Thanks.
