Thanks again for your assistant. I tried to measure some voltages and they appeared almost the same with my other t66. I am running out of ideas, what can cause the IC601 not to show the waveforms it should? what do you suggest? Thanks.
The sync signal originally from IC601 CXD1125. Pls check crystal of the IC, VCC and reset signals. The IC301 with 16.9344MHz crystal outputs clocks to pin53 of the IC601. Pls check the IC301 as well.
