I posted this question a couple of months ago but without any outstanding
success, so am reposting in the (feeble) hope that a Phillips 4CM4270
boffin has recently hooked up and is now reading this post :-)

Problem is:-
  
Intermittent loss of horizontal sync or no sync on boot up of PC.
  
Horizontal sync signal is erratic around transistors 7317 (BSV52) and 7320
(BSV52) on C.R.T. base P.C.B. - These have been changed along with ICs 7413
(TDA4850) and 7406 (TDA2595) on motherboard but no change in fault conditions.

All previous suggestions (for which I am suitably grateful) have been
investigated without success. If anyone else can shed any more light on
the problem then I may be once more able to utter the "P" word around my
house again :-)
