There is a remitter resistor between the base and collector. You will probably see that it's blackened on the side of it. Before replacing, look directly into the blue crt and you will probably see that it's cracked.

Don't see many because there isn't a philips dealer in this area. The high voltage O/P transistor is shorted. All power supply voltages appear normal, deflection aand audio is working. Question: there is 130V on the collector of the HV transistor 2DS1556 which is shorted so there must be a fuse or fuse resistor somewhere in the emitter line, could someone tell me the location and value of the fusable. Found tips on ptv620 and a .0019uf cap was mentioned as possible cause and to check the blue crt, does this apply to the 630 as well? Any suggestions welcome, may save an extra trip as I have to work on this on site. Al G Al's TV-Electronics Pembroke Ont.
