Simple really, something either is loading down output from 5 volt regulator
Q3600 to 3 volts intermintley. (possibilities many) or their are many
surface mount transistors which are either in reset or turn on, and one of
them is leaky. Can't really tell with out scamatic.

I worked on a CTC170 a while back . It was shutting down. I changed the caps
in the regulator like the CTC169 and it fixed it. Don't know what your
problem is. This was a 36" set not a PTK.
