Default Philips N4450

This has confounded me.

When you switch on the forward play and forward wind buttons light up.

Sometimes the machine goes into play, once or twice the capstans wouldn't start up unless you pressed stop.

I've changed the transistors on both flip flop boards and found a duff CB148 on one of the tension boards which I've replaced using BC547's & BC640's correctly orientated.

No improvement except I can now get the RH motor to turn.

Can anyone shed some light on this?
