This again!

I finally got the transistor & replaced it.
Results same as before - OnScreenDisplay doesn't sync horizontally;
all else seems OK.

Since I now have the set apart, I checked the waveforms.
H pulses OK at base and emitter of Q4402 look just like what the manual
shows. Also waveform right at pin 23 of the micro is OK.

Micro pins 25 &26 (the passive components of the PLL) don't look so
great, but there are no manual waveforms to compare them with.
Any ideas - anybody??
